Sowing seeds for cauliflowers

Am I to late to start cauli's.

I tried some in March but they just went leggy and with all the other jobs never got around to them again.

Yes I think they were too warm.  I will have another bash, but will also look out for the ones you suggest,

My cauli went a bit leggy so popped it in my salad box for protection against wind and banked them up a bit, they are transplanted out now and just getting their heads.I did see some plants in my local garden centre that looked good or maybe try swap shop.My psb got eaten but some lovely lady on there who lives locally is letting me have 6 of her plants !! worth asking.
