Full sun, very sheltered spot, needs protection from frost, so either start of under glass in a pot, or in the house. Plant out at end of May.

Takes frost okay--it grows in the northern Plains States--but it hates saturated soil and endless gray weather. Try giving it a south-facing slope, and mixing a lot of sand and a little organic matter with the soil.

Blimey, take your pick there, Guest, lol! Information I gave comes from Encyclopaedia of British Garden Plants and Flowers, so specific to Britain.

And I was going by what my aunt in Cleveland, Ohio does with hers! Guess that's why gardening is still considered half an art.
