Mine died
But they're not supposed to be difficult to grow.
But I know they like a cool soil, they seem to have no problem with clay, preferring this to a sandy soil (that has a tendency to be warmer and drier).
My Father used to grow them near the north-facing side of a cabin (in a fairly heavy clay soil (I should know, I had to dig the oeoeoe stuff) in the North West of England). Here they grew very well. A mulch of compost will not only feed them, but keep the soil cool.
They do not like a water-logged soil.
Good luck.
