Here’s another close up of a plant I mentioned in the post about my roof garden’s back wall, Oxalis squamata.
Oh how I love this plant. Even more-so than I thought I would. The flowers sort of remind me of the Oxalis corymbosa I saw in Dominica and St. Lucia, but smaller. The leaves are smaller, too and cuter still.
The growing requirements are certainly different. Oxalis squamata is native to the Andes Mountains in Chile. It grows among rocks and scree and therefore requires very good drainage. Despite that it also seems to need water every day or so, but that could just be the size of the pot and conditions on my roof.
I’m not sure what I’m going to do with it come winter. I’ve read that the plant can survive outdoors in my zone if the soil is extremely free draining and it is protected from excess moisture. Neither of these are conditions I can provide in-ground so I’ll have to wait and see what I can do when the time comes.
