Mine are in full bloom (thanks Zeedman for the seeds). I had one plant grow much faster then the rest and put on flowers 4-5 weeks earlier. The majority of the flowers fell off since there wasn't a pollination buddy, but strangley it did set 3 fruit. I'll be saving seeds from them with the hope of getting self pollinating offspring. Now that I have 10+ plants blooming they seem to be polinating easily.
I had some leftover soil from my raspberry pots so I have some growing in normal soil and some in acidic soil. They seem to be growing at the same rate, I was curious if it would affect growth and flavor.
Bumblebees love these things, I'd probally grow a couple just for the flowers even if the fruit wasn't edible.
