I first fell in love with oxalis, when I discovered all the variety in this genus. The purple three-leaf Oxalis triangularis is the one pictured here. This post was inspired by a comment from Tatyana about my deep purple leaf. I am enchanted with every aspect of this plant. It's leaves have a number of different shades of purple on their leaves. Each leaf is a triangle and they close like an umbrella when the sun shines on them or night comes.
The genus hails from Mexico, South Africa, and Brazil, but has spread to many countries. It grows year round here, but doesn't flower in the heat. It is also called wood sorrell and is edible, although I've never eaten it. Perhaps it would do in a salad, having a somewhat bitter taste. I love looking at it so much, I've never thought to eat it.
Its blossom is lavender, although it's a little hard to tell in this photo. The blossoms also close at night and in the sun. Mine is so used to Southern California now that only a week after a heat wave and temperatures now in the 80s, it has started to bloom again.
This is the small bed they live in with a cyclamen, impatience, and heather. As it gets cooler I'm going to add more oxalis to this bed, but two different varieties. I'll share those with you after they're up.
