We bought these flowers from the Suttons stand on the last day of the Edible Garden show last year (when they were selling off their displays).
I've not had much success in the past growimg primroses so I am very pleased that these have returned with lots of blooms this year.
So far, they seem to be reliable, grown as a perennial.
Seen here are Primula Balerina 'Nectarine' & 'Valentine'.
Ours are in a partial shady spot grown directly in the ground, but I think they would look gorgeous grown in pots.
