    You've written out the pronunciation of 'oxalsis' wrong. As is the case with many nouns, the accent is on the first syllable - OK-se-liss; however, when using the verb form of the word, as in 'oxalic,' then the accent is on the second syllable - ok-SAL-ik. (Case in point: syllable=SI-le-bel and syllabic=si-LA-bik) I hope you take my comment as much in the spirit of friendship as I offer it.

      We in Canada pronounce Oxalis exactly as it was indicated. What country are you from?

    Anyone know what zone this will grow in? I want to try it in the garden. I am Zone 5b in the US.
