Can anyone ID this Oxalis?
I have had this Oxalis, which grows from small bulbs, for well over 10 years and although it has 'spread' it is far from invasive. Its best characteristic, by far, is the fact it is totally dormant all summer before bursting into life mid to late autumn and then grows and flowers continually all winter, before dying down again in mid spring. Winter temps here can get down to -8C but normally I would expect to see -4C as the lowest. This would make it equivalent to Zone 9 in USA, I guess.
