Dracaena marginata,Triangle Oxalis and Purple flowered Oxalis

This plant is super common in the landscape here because of its drought tolerance. My neighbors have large ones that never get any water (except for rain water).

Heck,I've been told that the Triangle Oxalis (purple) grows like a weed in the UK. I work to get it to thrive here. Even then,it seems first plant to go dormant in summer.
It might need MUCH watering to do well.

The purple one grows wild here, also. I don't like any of them.

I think I've posted photos of the purple one all over the yard several year back...when we used to get some real rains.

a lucky plant :-)

I don't think Delonix we are talking about the same Oxalis.
This is. Q.triangularis....not a Oxalis with purple flowers.
But,I also have a purple flowered- more violet- green Oxalis in the photo so I can see how confusing it came out-lol.
Glad I made that perfectly clear..

Stan:

Oh I know which one you're talking about now. It can become a pest here, also. I've seen it. Not as much of a problem as Bermuda buttercup and the purple flowering one, though. Thank God! :>)

There's plants and trees in San Diego that have naturalized that in a million years I never would think would be naturalizing here. African Tulip trees grow wild in some of the districts in San Diego. Even on the grounds at San Diego State University they grow wild (which is a mile from me). It's because there's so many African Tulip trees there.

I also have Redwood Oxalis in my back yard. For once I can say a choice plant turned up on its own..and I do my best to encourage it. The Redwood Oxalis seems to flux..sometimes doing great..then when I think its died off...comes back a year later. Its supposed to be evergreen.
I would love for it to be a carpet but too much leaf litter,cat paws and me I guess.
