I've just re-potted my scotch bonnets which I grew from chillies bought from tesco. Coming along nicely, the largest have good leaves and are about 6 inches high. 6 varieties all told:
Scotch Bonnet
Anaheim
Demon Red
Tabasco
Hungarian Hot Wax
Jalapeno
Just used a couple of Jalapenos on a litlle pizza, delicious! The flat is now overrun by chilli plants!
