Oxalis deppei 'Iron Cross' on balcony 23rd May 2022

Now this brings back a childhood memory for me as my Nan had this growing everywhere! Well, it seemed that way to me when I was very young ... :o)

Glad it brought back some lovely memories from your childhood, Shirley! :)

It's true I grow it in pots but I don't find it invasive at all! However some little tubers must have made it into some pots of Daffodils that I later planted out in the gardens of my old church as I saw several leaves in different places! But they can't have liked the soil or whatever because they didn't seem to multiply & I never did see any flowers on them.

I was taking a few pictures the other day of the plants growing & flowering in the gardens but I didn't see any sign of this plant - probably because it is very early in the year yet & they don't show their heads before the start of May on the balcony.
