Hi Jay--these are pretty easy to propagate (but not the same as their african cousins). Sorry I don't have pictures. Every fall when the foliage dies down, let the undisturbed pots dry out, and place them in a dark, cool spot for the winter, but not frozen! When you're ready to start them, remove the contents of the dormant pot, and remove the bulbs. Plant them in fresh medium ~1" deep, place in a warm, sunny spot, and water them lightly. You should be all set. If the 'pine cones' are extra long they can be snapped into sections, but it's not necessary. You should have plenty to give away if you like. Just a few in a 8" pot will fill it up. If you keep these warm and watered over the winter, they won't go dormant. Happy growing! --Rick in CT

I have Oxalis regnelli as well as triangularis and Iron cross. I would like to trade for other Oxalis or other bulbs (see my wants list), if you have any. Susan

Just chiming in to this 7 year old thread to say that I bought a plant called "Oxalis Triangularis" on Etsy last month that fits exactly this description. It came in purple and green varieties. I was curious if the red/purple undersides were a sign of stress or just part of the plant, which is how I arrived here. There is very, very little information about the green version of this plant and I was so happy to learn more.

Lori, no offense taken... read below and you'll see why I think zone 5 (and that is only a "maybe"). In earlier posts I quite clearly said I have not tried to winter crassipes. I don't like it as it is just plain green... LOL Iron Cross O. Deppei foliage is much more attractive. If you don't have any in your garden I recommend Iron Cross as an annual ground cover. I have seen Pink Sorrel O. crassipes locally in other gardens here... I looked on several different websites (plant databases and googled it not just once) but you are absolutely right about the zones, thats why I started the other thread... I expect that they can likely make zone 5 not just because of the websites but because of the mass amounts of bulblets these little guys put out in a year. My experience with O.deppei and my familiarity with crassipes locally leads me to believe it won't winter in zone 4, I said "maybe zone 5". After winter is over here both deppei and crassipes bulbets turn to mush if they haven't completely gone rotten or become compost. I had too many O. deppei last year and this year I grew quite a few (but not too many, I know better now) LOL All the bulblets I left in the ground last year were mush. We had lots of snow this last year so it wasn't like they weren't protected. One of my relatives has a mixture of deppei (I gave him) and crassipes (same problem, mush). The bulblets all form about a half an inch below the surface and don't even take the first frost too well. I'm actually hoping to see more posts in the Zone-Pushing thread... I was surprised when a miniture rose made it through the winter and I'm hoping others will be surprised when they see what the rest of this group gets away with every year :-) I've tried a lot of new things this year in my garden... and leaving plants in the ground is one of the easiest new things I'm attempting this year LOL - Andrew
