I looked up Buddleia Blue Chip. I want one! It looks smaller and neater than the Buzz ones, but the Buzz ones come in different colours. I haven't heard of any of them. Perhaps they haven't arrived in Dordogne yet. Think I'll go to Jardiland (GC) tomorrow!
I've got a two year old Buzz and I can definitely say that they grow to 5ft and not smaller as some say in their write ups on this new variety. Blue chip looks like it actually grows to 2ft so would be perfect in a tub on a patio. Would be nice to have feedback from gardeners on how the plant grows when it becomes more established. Just to say that buzz just keeps on flowering constantly but I do dead head the spent flowers on a regular basis.
