Hedgehogs, Floral Tapestries, and Design Inspiration from Harlow Carr

Hedgehogs, Floral Tapestries, and Design Inspiration from Harlow Carr

One of four public gardens run by the Royal Horticultural Society, Harlow Carr is set in the beautiful English countryside near Harrogate, Yorkshire, so of course I just had to visit while I was there a few weeks ago. I wasn’t sure what to expect but found myself totally charmed and impressed by the varied displays that were both inspirational and educational. These are just a few highlights from the 200 or so photos I took!

Hedgehog Street

Openings at the base of the walls allow hedgehogs to pass from one garden to the next

The British love their hedgehogs. I have fond memories of setting out a saucer of milk for night-visiting hedgehogs when I was a child, but sadly their numbers have been in a rapid decline as hedgerows have been lost and their natural food sources destroyed. A national campaign called Hedgehog Street has called for greater awareness and pledges to make gardens more hedgehog friendly by:

  • planting nectar-rich flowers that encourage insects that the hedgehogs eat
  • leaving piles of dead wood and compost for nesting sites and foraging
  • Avoiding chemicals on lawns to protect earthworms – a major food of hedgehogs
  • Avoiding the use of molluscicides and pesticides
  • Including a 13cm (~5in) diameter hedgehog highway between gardens for greater connectivity

I loved this example of a hedgehog-friendly design, designed by Tracy Foster and installed by First Light Landscaping. Truthfully, I stopped because I thought what a great example it was for ‘small space design‘ – it was only on closer inspection that I realized it had been designed to be equally beneficial to hedgehogs!

Embracing the Earthworm

Throughout the gardens there were fascinating willow displays including a huge stegosaurus protecting its eggs and this  wiggly worm that made me smile.

Floral Tapestries

Expansive beds were richly planted in a matrix of colorful perennials, an exciting take on the New Perennial Movement and a twist on the traditional English cottage garden style.

Mature trees added punctuation points to the intricate displays

Each block of color was clearly defined in most areas…

…yet rivers of certain perennials were allowed to flow more organically through other beds

Edible Ideas

The kitchen garden display was especially interesting.

Apples were espaliered on wide steel arches

English gardens are often small so making the use of vertical space is always a priority.

A gourd tunnel is created around a pathway using pruned branches

Rather than growing a traditional tall bean tepee where one has to get a ladder to reach the top, I thought this was a clever idea:

Growing beans at a 45′ angle makes harvesting easier and shade loving crops can be grown beneath

These twig prunings were put to good use as “pea staking”, preventing chard and nasturtiums from sprawling onto the path

Traditional “pea staking”

A thrilling moment

Harlow Carr also has a wonderful library that is open to all: students, researchers, and everyday gardeners. The collection includes practical gardening, garden design, wildlife gardening…and MY BOOK!! Yes, Gardening with Foliage First (Timber Press, 2017), my second book co-authored with Christina Salwitz, was proudly displayed on their shelves. This was one of those moments that I would have loved to have been able to share with my Mum. I know she’d have been as proud as I was.

What does deer-RESISTANT mean?

What does deer-RESISTANT mean?

If you share your garden with deer, you’ll be familiar with the term, and when shopping for plants have undoubtedly asked nursery staff for assistance in choosing things that are deer-resistant. Yet what does that really mean?

Let’s be clear: it does NOT mean deer-PROOF.

With that out of the way let’s dive a bit deeper so you can make informed choices when choosing plants and strategic decisions when siting them.

Start here:

My go-to reference for whether or not a plant is deer-resistant is the Rutger’s website. The great thing about this site is that it is backed by considerable professional experience and observations and lists a plants LEVEL of resistance (more about that in a moment). The downside is that they are based in New Jersey, so there is some significant variation in their observations and mine here in Washington state. It is, however, an excellent place to start.

Understanding levels of deer-resistance.

It isn’t black or white – there are levels of resistance that it is helpful to understand. The Rutger’s website site uses the following grading system:

A = Rarely Damaged
B = Seldom Severely Damaged
C = Occasionally Severely Damaged
D = Frequently Severely Damaged

They recommend selecting plants that fall into categories A or B if you share your garden with deer, unless you are willing to protect plants with fences or sprays.

But what does “seldom severely damaged” look like?

Let me share a few case studies from my own garden to give you an idea.

New Guinea impatiens (annual)

Although this species (Impatiens hawkeri) is not listed on the website, both Impatiens balsimina and Impatiens walleriana are listed as level C, so one could assume a similar rating for New Guinea impatiens.

I have one New Guinea impatiens in a container design along the primary deer route. It has been there for 8 weeks without any damage whatsoever.

How it USED to look!

Two nights ago this happened…

So, yes the damage is occasional, and yes it was severe – but they haven’t destroyed the whole plant, just taken off about 90% of the flowers! One squirt with the deer repellent spray would have avoided even that but it has never been eaten before this year and I’ve grown them for at least three years in containers exposed to the deer… (i.e. ” VERY occasional damage”….). The good news is that everything else in the pot was untouched! Knowing (and seeing) that, will you include these and spray them – or avoid them entirely?

Sekkan-sugi Japanese cedar (conifer)

We began to develop a large privacy screen about 7 years ago. It includes conifers, deciduous trees, broadleaf evergreen shrubs,  and grasses.

The privacy screen acts as a buffer between ourselves and the neighboring property

In the center of the photo above you can see a beautiful golden Japanese cedar, (Cryptomeria japonica ‘Sekkan-sugi’). When it was still quite young the deer did one of their nightly stealth raids and this was the result:

Rutting damage

They didn’t eat the tree – but they did damage it by rutting against it. Thankfully the conifer coped with the damage and seemed to grow out of it over the next year, so I’d agree with the rating of B. I would advise also fencing the tree when young to get it established.

Corkscrew hazel (deciduous shrub)

I love the twisted foliage, stems, and catkins on the Red Majestic corkscrew hazel (Corylus avellana ‘Red Majestic’)

Nibbled stems on my corkscrew hazel

If you only saw the above image, you’d be tempted to think the entire shrub was a loss, but that isn’t the case. See it in the broader context:

Bigger picture – NOW can you see the damage?

The shrub is at a turning point in the path – and on the major deer-highway. It was easy to taste a few convenient leaves but they clearly didn’t deem it tasty enough to devour more.

That being the case, I’d agree with the Rutger’s rating of B (“seldom severely damaged”). Plus the shrub has been here for three years and I think this is only the second time I’ve noticed any damage at all. So will you choose to grow it?

Now what?

Now you can make informed choices about the plants you select, assess your level of tolerance for damage, and decide where to place these plants in the landscape. For example, I’d suggest any major focal points and specimen plants are always selected from A or B. If you really want to try something listed as C or D then at least set it farther back into the border so damage is less noticeable and don’t use that plant for an entire hedge!

Footnote 1 – Rutgers vs. Karen

Where I differ from Rutgers:

Heavenly bamboo (Nandina domestica cvs..) are totally decimated by deer in my garden (D+!). Rutgers lists it as C – which I think is a change as I swear they used to list it as B! (In Texas and North Carolina it is actually considered at least B)

Gold dust plant (Aucuba japonica) – in WA they are C or even D. Rutgers lists it as B.

Footnote 2 – What Rutgers misses

Arkansas bluestar (Amsonia hubrichtii) is not on the Rutgers list – I would rate it as A, never having had any damage whatsoever in 7 years. It is also my favorite perennial of all time!

Telekia (Telekia speciosa) is a large, shade-loving perennial with steroidal foliage and yellow daisies. It takes a few years to outwit the slugs here in the PNW but mine now reliably grows to 5-6′ tall each year despite deer, rabbits and our over-abundance of molluscs. I’d confidently rate it as A since the deer walk past it every day. (Not listed on Rutger’s)

Gaura (Gaura sp.) is also conspicuous by its absence from the Rutgers list. Most definitely A++ here.

A special gift for you!

Deer-Resistant Containers: Before & After

Deer-Resistant Containers: Before & After

I thought you might like to see how some of my summer container designs have grown in. All three designs are planted in full sun, are deer resistant, and low maintenance.

The “After” images are approximately 6-7 weeks after planting. They all had Osmocote added as a slow release fertilizer when first planted but have not had additional fertilizer since then. Nothing has been deadheaded or cut back except where noted.

Contemporary and Monochromatic

May 19th 2018 – just planted

You may recall helping me design this container! It has looked good from day one, although the ornamental oregano I originally planted did not do well for some reason and has since been replaced with a similar variety called Kent Beauty.

August 1st 2018

I’m really enjoying this! I love how the colors continue to work with the surrounding landscape and how full and luscious the design now looks. Notice though the discrepancy between  the size of the two silver leaved plants (Senecio ‘Angel Wings’). That is because they were purchased from two different vendors and is a reflection of their varying fertilizer and growing regimes. Both plants are gorgeous and healthy, but one is much bigger. Lesson learned….

Plant list:

Platinum Beauty lomandra

Angel Wings senecio

Kent Beauty oregano

Quicksilver hebe

Red Threads alternanthera, Joseph’s coat (hidden in this image but you’ll see where I added it in the original post)

Quick, Easy and Colorful

June 1st 2018 – just planted

The Orange Rocket barberry has been in this pot for several years – I just prune it a little for shape as needed. Truthfully there was zero effort or thought put into this design – I just grabbed three each of three different annuals, focusing on foliage and reliable performance.

July 31st 2018- on a hazy summer day!

I didn’t use any long trailers in the design but I like the ruffle of white euphorbia blooms and that blue fan flower is a rock star! Non-stop color and zero maintenance. (I ought to trim away (or move) the barberry at the base of the container as it is visually interfering with the design). In the photo at the head of this blog post you can see how it looks in the context with the cabin and surrounding landscape.

Plant list:

Orange Rocket barberry

Glitz euphorbia

Fairy Blue fan flower

Walkabout Sunset lysimachia

Demonstration pot

This was the container I planted in the demonstration video for my online course Designing Abundant Containers . It has evolved beautifully as the perennials have changed personality and the annuals have grown. Initially the false indigo and Ascot Rainbow spurge had blooms, but the annual verbena was just waking up. Colorful foliage helped to bridge the gap.

May 14th 2018 – just planted

Just over four weeks later and the Ascot Rainbow spurge is still flowering but the false indigo  blooms are now small seed pods – and look at that verbena!

June 19th 2018

By the beginning of August I had trimmed off the spent Ascot Rainbow blooms and was surprised to find another flowering stalk already emerging. The verbena took a two week break from full bloom, although it was never without color. As flowers finished I cut off the developing seed heads…. and then this happened! I struggled to photograph it in the same location as it is now so much wider!

August 1st 2018

I was pleased that although the silver Angel Wings senecio has got taller it hasn’t become “leggy” and that there is still a wonderful density to the abundant, felted foliage. I also like the the way the lemon thyme fills in the front and the verbena mingles unapologetically through it all yet never overwhelms.

Plant list:

Cherries Jubilee false indigo

Ascot Rainbow spurge

Tequila Sunrise mirror plant

Mexican feather grass

Diamond Frost spurge

Purple Queen

Angel Wings senecio

Lemon thyme

Royal Romance verbena

 

I’m about to head out of town so won’t see these again for a while. My daughter is in charge of watering while I’m away…..I wonder if they’ll look past their best when I get home again or still be photo-worthy?

I hope this series of images helps you see the value of designing with foliage first (I do believe there is a book about that!), and encouraging you that a deer-resistant design can still look both colorful and interesting.

If you’d like more help designing with deer in mind, stay in touch via my newsletter. I’ve been busy creating a special online course Designing a Deer-Resistant Garden that you won’t want to miss, as well as my new book Deer-Resistant Design; both will roll out in June 2019. And as a thank you for signing up for my newsletter I’ve written this FREE guide just for you. Enjoy!

Last Needle Hanging

Last Needle Hanging

Seen above in better days….

The conifer is failing

…but sadly a key plant in this scene has now become an embarrassing eyesore.  Time to take action!

Out with the Old

My Feelin’ Blue deodar cedar (Cedrus deodara ‘Feelin’ Blue), carefully placed to the left of the cabin, started to feel a bit “off” last year – and turned a dull olive green. This year she is decidedly brown. I could wait  until the last needle drops or just face the inevitable and dig her out. This is a prime location, visible from the home, the patio and even when driving onto the property so it’s not place for a Charlie Brown. I also painted the door of the cabin to match the conifer….. Geez, did she not understand that before she started with her chameleon attitude?

Not the look I was going for!

But what to replace her with? I like the idea of a conifer still, it needs to be low and spreading (so the cabin and orange container behind it are not obscured, it needs to be deer resistant, tolerate full sun, be drought tolerant once established – and be BLUE. The soil isn’t great in that spot. The native soil is clay and while it has been amended I suspect the water table is quite high which may mean soggy winter soil and be the reason for the demise of the deodar cedar whose sensitivities were upset by the short-term foot bath.

In with the New

Love the visible white stomata on the needles of the Spreading Star Pacific fir

I’ve chosen a selection of a native fir – the Spreading Star Pacific fir (Abies amabilis ‘Spreading Star’). I love the deep blue-green needles that radiate around the stems and the distinctive silver-white undersides which add a shimmer effect. It will grow to 6′ wide x 3′ tall; about the same size as the failed cedar that is being removed.

Regarding deer resistance, I’ve been fortunate with deer and fir interactions so far, the only casualty being rutting against a Korean fir, so I’m fairly optimistic on that front but may spray the first couple of winters to give it a chance to get established.

I’m not sure how it will fare in my soil, except that I have two other fir in the same border that are doing well so again am cautiously optimistic.

Temporary Design Assistance!

Silver Falls dichondra is often used as a trailing silver-leaved annual

 

The only problem is that while it will eventually grow to fill the space, right now it’s tiny! It would be easy to fill up the space with a wild assortment of bits and bobs but I want this to be a distinct focal point to anchor this bed and not get lost in a cacophony of botanical treasures. I’m therefore going to surround it with a temporary silver carpet of Silver Falls dichondra.

I like the silver color echo between the fir and the groundcover, and also the difference in leaf shape and texture

The small, metallic silver leaves will accentuate the color of the conifer and act like a series of floodlights lighting up the star. I know this is only an annual for me, but it’s a fairly cheap, short-term solution that won’t spoil my overall design.

Early results

The new look – day 1

Yes it IS small, especially when I’m used to seeing the larger conifer, but I like the direction this is going in now. Framing the fir with the silver groundcover really sets it off as I’d hoped. And I love it with the door!

Mission Impossible? Petunia Conversion!

Mission Impossible? Petunia Conversion!

“Oh boy,” was my less-than-enthusiastic reaction when I opened the box of plants to trial from Proven Winners and saw several petunias. PINK petunias at that. I can’t stand petunias. They get sticky, messy, don’t deadhead politely, get covered in aphids, don’t tolerate rain – and pink is NOT my color…

As I donned my gardening gloves and pushed my pride to one side I tried to focus on the fact that I was being asked to test these plants as a real gardener so that YOU would have an unbiased review of their performance. Sure it was going to be unbiased. I hate petunias. Did I mention that already? And I don’t especially like pink. I’m not completely averse to pink – I just wouldn’t choose it.

I hastily shoved them in a couple of spare pots adding whatever I could round up to work with them (did I mention that I don’t “do” pink?) and set up the drip irrigation system.. I then left town for 10 days – for 8 of which it poured with rain. When I got back home did I rush out to see how they were doing? Noooo. I hunkered down in my office for another 8 days to finish writing my book, during which time it rained – a lot.

When I eventually emerged and ventured out to check on them I anticipated a sticky, molten mess. I kid you not – they were stunning. No sticky goo. No aphids.

I didn’t even primp them before taking these photos – this is as real as it gets!

Et Voila: Supertunia Vista Bubblegum

Of the two, so far, I’d say Vista Bubblegum has a tidier habit – no awkward sprawly bits – and it is playing beautifully with the delicate, silver Artemisia ‘Makana Silver’. And although I don’t go for pink as a rule I could honestly be tempted by this one. It’s a lovely clear shade of pink with deeper veins- not too bright and not too pale. I think it will hold up well to bright summer sun come August. And just one little plant is really giving a lot for the money.

….and Supertunia Vista Paradise

Supertunia Vista Paradise is a little more sprawly but not excessively so and I am deliberately not going to pinch it back as I want to see how it performs on its own. Chances are it will even out and have a similar habit to Vista Bubblegum.

Supertunia Vista Paradise with a blue fanflower (Scaevola), Sedum ‘Lemon Coral’ and a lovely new Angelonia called Angelface ‘Steel Blue’ that will be available in 2019. All except the fanflower are from Proven Winners

It’s a really deep shade of neon pink that looks stunning with bolder shades of yellow and blue-purple so is a little closer to my usual color tempo. This one will be available in nurseries in 2019

Stay tuned for a late season follow up but dare I say I am impressed? By a petunia! Proven Winners  you have achieved the impossible.

Although the plants were from Proven Winners I have not been paid to give my endorsement. Opinions are my own and unbiased. (I DID tell you that I hate petunias, right?)
