Matt, I would gladly have a lawn of bulb Oxalis vs. grass, but it's dormant too much of the year to function that way, disappearing during the coldest & hottest weather here. Beloved ground cover around/under shrubs when it's "up" though! If your summers are less hot, might be something to investigate, a test patch. The 2 I've encountered so far are definitely hardy here, O. crassipes & O. triangularis.

I have oxalis. All around. The green with purple flowers. If they weren't so annoying, I would probably like them. and wait a minute! While I was trying to figure out my other hated weed, I found out it, too, is oxalis. It's a much smaller leaf, with small yellow flowers. I also fight with rattlesnake weed (Florida Bettony). It grows much like the previously mentioned, only it's roots and tubers grow further down and are much more fragile. We also have vines. Lots and lots of vines. Many of them have thorns. Fun stuff.

I feel your aggravation! I tipped some Dyckia plants out of their pots yesterday to remove the Oxalis corniculata, it actually went pretty quick, and was certainly easier than trying to tease the weed out from all that spiny foliage. Doesn't it always seem that this weed grows best where it is most difficult to remove? The red leafed version is actually somewhat ornamental on its own merits, but still a weed! One Oxalis that I actually do plant a lot is not a bulb, and not invasive, and comes from high elevation Costa Rica, Oxalis spiralis volcanicola. The different foliage forms of this Oxalis spiralis such as Velvet Sunset and Burgundy are also beautiful and well behaved. It seems in the past 5 years this Oxalis has taken the country by storm, used as an annual in hanging baskets and mixed container plantings back east. I first became interested in landscaping with this species some 20 years ago when I first saw it at Strybing Arboretum, and there were no commercial sources for the plant. It also looks spectacular in mass, as I've used it here: Here is a link that might be useful: Oxalis spiralis volcanicola

Lovely bouquet for winter jkom. I have some purple reblooming irises as well and even though it is winter and we had snow the week of Christmas, I have one plant that has sent up a bloom stalk. I am sure it is frozen by this stage but it is amazing how plants can put up bloom stalks at such weird times of the year!
