Has anybody any tips for growing these things outdoors?
When I transplant them outdoors, they huff and puff and really dont live up to their common name.
I saw a fantastic display in a garden in Dublin once, where the plants formed a lovely 2ft (60 cm) spreading mat of pale pink at the edge of a border along a path. At the time, I assumed it was one plant which had spread, but now I'm thinking it must have been a mass planting of plants of the same colour.
Ive tried a number of times to recreate this effect, but no luck so far. Ive 2 attempts again this year, with the plants set out about 6in apart.
