I need more plants.
One of the joys and frustrations of starting a new garden is watching it grow. For once I'm trying to be restrained and allow room for the trees, shrubs and perennials to expand to their natural shape and size without jostling neighbors yet that means I can see bare soil -definitely not my usual garden design style.
The main problem exists in a large island border where all plants have to thrive in full sun, be reliably drought tolerant and deer resistant. I also need BIG plants that make an impact due to the scale of the border as well as its setting within our 5 acre property. No wimpy pansies here! Even though the deer have so far ignored the trees and shrubs I've planted they still seem to think that it is acceptable to walk through my new border rather than go around. (It seems my dog was easier to train in that regard).
So to eliminate the deer-freeway, reduce visible bare ground and to fill the gaps between immature plants I have decided to use annuals in a few spots. For budget reasons I have grown these from seed but most can easily be purchased as plugs from the nurseries.
'Fireworks' Globe amaranth (Gomphrena) – This one is new to me ; a good enough reason to include it! It quickly grows to form a full, dense, landscape sized specimen, eventually reaching 3-4' tall and 1-2' wide which equates to a lot of plants for a $3 packet of seeds. Tons of strong, tall stems are topped with exploding bursts of full, large 1" blooms in hot pink tipped with bright yellow. A showstopper in the garden and conversation piece when cut for a mixed bouquet. Should be gorgeous.
Hibiscus 'Mahogany splendor' – A beautiful foliage plant, this attractive variety has shiny, maple shaped leaves in deep, dark burgundy giving the appearance of a choice Japanese maple at a fraction of the cost. Every part of this plant is dark, making it a good choice for contrast with silver foliaged plants such as wormwood (Artemisia). Grows 3-5 feet.
Love-in-the-mist (Nigella) – I have a love/hate relationship with this pretty annual. It self-seeds which means free plants next year BUT they will undoubtedly re-seed where I don't want them! Thankfully the extras are easy to identify and pull out. Dainty, multi-faceted blossoms are followed by striped fairy lantern seedpods over delicate feathery foliage. Blue is the usual color but I have selected white and simply scattered the seeds amongst 'Walker's low' catmint (Nepeta). This soft color scheme will break up areas of bolder colors and is anchored by my favorite narrow conifer; false cypress 'Wissels' saguaro' (Chamaecyparis l. 'Wissel's saguaro').
'Violet queen' spider flower (Cleome) usually comes in shades of rose or white but this variety has unusual purple flowers which intrigued me. What really got my attention though was its promise of heat and drought tolerance and ability to survive neglect! It is also a butterfly and hummingbird magnet – my kind of plant. At 4' tall and with a succession of blooms all summer long this may become a 'regular' even after the garden has filled out.
'Carmencita' castor bean (Ricin communis 'Carmencita') –The deep red maple like leaves make quite a statement on stems that can reach 5' tall. Flowers resemble red pompoms held high on bamboo like stalks. All parts of these plants are extremely poisonous so do not include in the garden if you have small children or pets who are likely to eat fallen seeds or leaves. I'm planting a large mass of these near some Canna 'Tropicana' which I saved from last year, with the burnt orange 'Flasher' daylilies in front and a wave of feathery blue star (Amsonia) to one side which will turn bright yellow in fall.
You don't need to have deer in your garden to choose these plants! If you are looking for an inexpensive way to fill a large sunny space with color that doesn't need deadheading and is remarkably drought tolerant then these top 5 picks could be perfect for you too.
Other sunloving, drought tolerant, deer resistant annuals you light like include;
snapdragons, poppies, helichrysum (great for foliage), sage varieties, zinnia, ageratum
