What to plant in lava rock

genghisbunny(9)April 24, 2013

I have a narrow bed between my house and patio that I would like to utilize. I am imagining an edible low growing perennial. I have considered blackberries, which do well in my area. But they all seem to get very tall. I have also considered blueberries. But I'm not sure if they would like the environment in the lava rock. The rock goes about 4-6 inches down. There is black plastic below that. I'm not excited about taking the plastic out, so I would like something that wouldn't mind. I certainly can (and have in the past) add gardening soil on top of the rock. But it eventually filters down into the rock. I am successfully growing Wandering Jude there right now. But I would like to replace it with an edible. What are your suggestions?

That's a good suggestion, but what are the dimensions of the bed? How coarse are the rocks?

The bed runs along my house and is roughly 18 inches deep. I looked at the Emerald Carpet, but it seems to be non-fruiting. Is there a variety that I have missed?

Oh, and the rock is about 1.5 to 2 inches wide. It is the standard size you would see as an ornamental ground cover.

Do you have sun there or is it shaded most of the day?

The rock is too coarse for planting for planting ground cover-type plants. It could remain if used as a single-layer topping on the soil.

Thank you, melikee. That looks very interesting. It may be just what I am looking for. I wonder if I could do a test patch.

milehighgirl, it does not get sun until afternoon.

Thanks for all the help!

That Rubus will do fine with partial sun.
