Last month, Margy and I were talking about the crabgrass that has overrun the lawn in so many places, including the strip between the sidewalk and the street. This strip seems to be referred to by many names–from “hell strip” to “esplanade.” She is working on other strategies for other places, but I had the idea (after some internet research and an appreciation of what someone in our neighborhood had done to theirs) to see if hardy perennials might eventually outcompete the crabgrass and solve the problem. Then it truly would be shifting from a hell strip to an esplanade!
I started off by moving some turkish rocket from our backyard garden to the front. Turkish rocket is a fast growing perennial vegetable with beautiful yellow flowers. I had planted some last year, excited to try it, but this spring discovered that I didn’t really like the taste of the greens–they were too sharp and bitter for me. But the flowers were amazing. So I decided that I’d move it from the food forest to the strip. Another friend came by and transplanted some yellow day lilies and blue cornflower that needed a new home!
I put out a call on our permaculture meet-up, and was gratified when another member, Sandi, responded by saying she had a lot of perennials that needed dividing and we could have them. That’s the thing–so many wonderful perennial flowers multiply of their own accord and expand out of the area they are originally planted. So why not use that spreading habit to achieve a better use of the roadside space–for pollinators and for beauty. So I went out to her house and we dug up a whole bunch of plants.
That weekend, our friend Lisa was visiting, and she jumped in to help me with the transplanting effort. And it was a big effort! In the end, we had 24 new plants along the strip, mostly with blue or yellow flowers, which we tended to alternate. Several patches of Siberian iris and several patches of allium; anise hyssop, heliopsis, calendula, white ruffled iris, goats beard, astilbe, mallow, and lady’s mantle. The other day, I added some catnip–another plant that can spread, but hey, maybe it will outcompete the crabgrass, and we’ll also have catnip for the cats. The whole thing doesn’t look like much yet–a bunch of scraggly transplants, only a few with any flowers right now–but we’ll see how it goes next summer. If we can get a load of wood chips, we may put down some cardboard and wood chips between the plants. But that can happen later too. I will let you know how it goes.
Oregano. It speads, great groundcover, long blooming. I was surprised it was hardy here in Zone 5. Also thyme. And they both smell great when you are weedind. And they both stay green here for months after first frost.
Hey, great ideas–I have both in our food forest around trees, so it would be easy to transplant patches of it.
