I've got small plants in a pot ready to plant out.

I bought the seeds online from Seeds-by-Size for a fellow allotmenteer so I thought I'd give them a try. Because they're going to be in the ground for about 3 years I'll have to be very careful where I plant them. Aparrently they make quite a substantial plant similar to a PSB so they'll need a good bit of space as well!
I already have Jersy Walking Stick cabbage planted up my allotment edges which will be in there for a couple of years so I may interplant the cauli's inbetween them!
PS I haven't tried them before but the guy I got the seeds for says they are really good, producing up to seven cauliflower heads per season from each plant!
