Its a native here in my part of Texas, grows in part shade and is a good nectar source for Monarchs and other butterflies. I was intrigued by its form last year and blocked off 2 areas and let it grow naturally. I'd say last year I had about 50 or so. Saved some seed and hope to have at least that much next year. On a hard freeze, the sap oozes out and makes these "ice crystals" with different shapes.
