Answer: This plant can be difficult to grow. It needs soil that is very well drained and somewhat alkaline, and would do well in a gravelly alpine bed. It is listed for full sun, but in hot summer climates sun all morning is usually ample. (Afternoon sun would be too warm.) Since it needs such good drainage, take care not to plant it any deeper than it grew in the pot. It also appreciates a gravel mulch so moisture will not sit under the foliage or around the crown. This seems to help with the "melting" problem as well. In my experience, it is not very happy when the humidity is high, so try to make sure it is in a spot with good air circulation and avoid wetting the foliage whenever possible. Finally, although it needs good drainage, the soil should not actually go bone dry. As I said, it is not an easy plant unless you happen to have the ideal site for it. Good luck with your lithodora!
