I have to smile when I prepare this post. Oxalis were considered a pest where I grew up in Australia. My father would spend hours weeding oxalis – a purple species – from our gardens. He is probably spinning in his grave as I respectfully document Oxalis spp. as wildflowers.
All plants appeared similar
Oxalis stricta. The petals are yellow with little or no red color. If the red color is present, there is just a suggestion of red
Oxalis priceae. The red color is unmistakable; concentrated and distinct
Oxalis grandis. The red color is unmistakable, in clear patches and somewhat diffuse
These Oxalis spp. are native to the United States. Oxalis stricta grows widely in the United States and Canada; notably this species does not grow in the southwestern states. Oxalis grandis and Oxalis priceae are limited to the southeastern U.S.
