What's going on here (Oxalis)

I have had the same experience as Mary Sue with some O. compressa which came from BX . It is shy to flower and very similar to O. pes caprae, but for me it is shorter and more likely to have maroon spots on the leaves. I had kept it in pots, and it is a prolific increaser. I have some in the ground as well ( the oxalis escape ship sailed a long time ago) and there it spreads slower that O. pes caprae and is possible to distinguish the two.

During the oxalis wars I have found that it can send a shoot  a long ways in search of sunlight when trapped under weed cloth, cardboard etc. So 2 feet is not surprising. The stem is really the root system for these plants, the new bulblets form along it.

Happy gardening,
Chad Schroter

Dear Friends,

	I truly appreciate all the responses. Just a bit more back ground info:

	This is a self sown plant, but I do recall getting an O. compressa ( lost the terminal ‘a’ along the way somewhere), but after the responses, I can find no hint of compressed ‘anything’ leading me to believe it is O. pes-caprae which also gives more sense to its weedy proclivities. 

	This is NOT a small plant. Th entire length of plant from bulb to tip of flower scapes is around 32 inches- over 2 and 1/2 feet long. Individual flowers are over 1 in across.

	Although I seem to have pulled plenty of these out of the gravel floor of my greenhouse, I just donj’t recall this odd stolon.

	I gather that it is far from uncommon and others have seen this.  I do not grow many Oxalis purposely and pull almost all seedlings eventually.

	Perhaps this has shared the odd structures with other Oxalis novices like me. Thanks for the input and expertise.			Jim W.

looks like a 'keiki' on a 'stolon',  all ordinary behaviour for many Oxalis....
