Hi Potty, welcome to Goy.
I got some from J Parkers but that was earlier in the year. They were very small plants & took a lot of looking after so I would'nt recomend them.
They are selling them more in the GC now, so I would keep an eye out there, then you can choose your plants :-)

Sorry i have no advice but i follow a popular blog and she has grown them with success this year.

They look very tempting.

Sensei that is where I first saw them! Nice little blog, it has been giving me inspiration and a few smiles for the past few months.
By the way your cat matched my newest greyhound!May I have her???? LOL!
Seriously though, both my greyhounds love my cats. I sing the praises of well chosen, rescued, racing dogs whenever I can

I have a staffy and she treats my cat ike her own born. Though my cat treats her like hes the king lol.
Your dog has a very cute "innocent" face :D
