What I mean is... what you can do with a 'planting depth' of 19"..:)
I like to design and replant the side of my driveway every few years. Here are a few design ideas of what you can do with a shallow depth of planting space. My first design was with Light pink/coral Knock Out Roses and Blue Switch Grass, Panicum virgatum 'Heavy Metal'.
I enjoyed the early growth of both the roses and the grasses. Later in the season, I had to snip the roses to keep them from spilling out too much, while still retaining their free-flowing look. The switch grasses made a nice compliment to the roses with their soft breezy movement. In the Fall, however, the grasses started to flop a bit, so I had to prune here and there. I kept the grasses up through the Winter, so that I'd have some structure in the bed with their tan colored seed heads. I usually prune grasses early Spring. I love the lush look. I might do this again, maybe with deep red roses...:)
Another design idea: Euphorbia 'Blackbird' with the Variegated Reed Grass Calamagrostis x acutiflora 'Overdam' and the ground cover Sedum rupestre 'Angelina'. The euphorbia and sedum are evergreen, so you'll have something in the bed during the Winter.
In the Fall, I planted the dark purple/black 'Queen of Night' Tulip. They made a dramatic statement the following Spring. I wasn't happy with the reed grass because the location was too hot for this grass. It can't take the heat as well as its parent 'Karl Forester'. So, if I was to recreate this combination again, I'd use 'Karl Forester'.
Here's my current 'look'. I started with finding the right evergreen plant. I decided on the columnar Japanese Holly, Ilex crenata 'Sky Pencil', which gives a linear upright structure and great for tight narrow spaces. This year, I decided to go more vibrant in my color selection, so I planted Canna 'Tropicana' with the sun tolerant red/orange Wax Begonia and the dark purple/blue Lobelia to bring out the colors of the canna foliage. For added interest and strengthening the tropical feel I planted the Dwarf Fountain Grass, Pennisetum alopecuroides 'Hameln'. So far everything is growing nicely. I should be getting vibrant orange canna blossoms in the next few weeks. I've been making sure everything is watered deeply, especially since we've had many days in the 80's and 90's.
Anyone else have a shallow planting bed design you'd like to share?
