Bermuda buttercup (oxalis)? The invasive weed that has tiny bulblets that fall off every time you pull one? Trash 'em. I compost almost everything, including dryer lint and dog hair (we brush a handful a day), but I send few things off to the city's greenwaste bins (or trash!): noxious weeds such as bindweed and bermuda grass, thorny plants such as rose canes, and weeds that have gone to seed that I don't enjoy pulling out, such as most grasses. Plants that are toxic to people are, in general, no problem. Exceptions would be skin irritants such as poison oak/ivy or anything with big prickles/thorns -- they *can* all be composted, but for me they wouldn't be worth the trouble just in case they didn't fully compost. On the other hand, comfrey and borage (which have irritating hairs) make great compost and compost tea, they quickly compost, and the hairs do not survive composting. If you did want to compost those noxious little bulblets, I'd pretreat them: smash with a hammer, leave out in the sun to dry out, soak in water for a long time until it turns to slime, etc. For the very small amount of noxious weeds I find, it's not worth the trouble to make sure they're nonviable. I got some "potting soil" on freecycle that turned out to be infested with these noxious weeds, and little by little I'm getting rid of them as they appear. Most of the time, they go in the trash.

I had great success with the gomphrena last year, and didn't do anything special. I was kind of surprised that my results were so dismal this year. Funny, in looking back at my records just now, the ones last year were sown in mid-February and did great. This year I sowed them in the first week of March, and got three seedlings. Hmm. Well, as every gardener says, there's always next year! :) Dee

There are no species found in this area (SE GA coastal plain). I have read that they do not grow in tropical and semitropical lowlands. I suppose it's the heat and/or humidity. that they can't tolerate or absence of a cold dormant period. They seem to multiply with abandon in the northern climates, as does many other Genera/species in the Ranunculaceae Family (Actaea, Anemone, Hepatica, Helleborus, Aquilegia, etc.), that are not found in this area and does not establish in cultivation. On the other hand, the transplanted native Oakleaf Hydrangea loves the perfect drainage of sand and once established, best get out of it's way!

Hi Hardy little devils aren't they. ?? lol You will never get rid of them lol. I always whack them down whenever they get too tall. .and pull them whenevr I see new ones. Watch your pots and raingutters they'll grow quite happily there too lol They can get at least 6 feet tall but get very leggy. If you give them some good soil and a shot of fert. they'll flower like crazy and twice as big. They seem to die out after a while so wouldn't be too good a shrub. There is a pale yellow type with a black eye ,much shorter and more prostrate .Also a hybrid between the two . gary
