Hi Looking for a bit of advise, have just ordered another Crambe Cordifilia this year as last year tried unsuccesfully for my first attempt at growing one. It lasted approx 1 week and wilted and passed away. This was just as the rains began so no shortage of water. We have a heavy ish clay based soil, I would be greatful of any ideas to keep this young beauty. Or are they notoriously difficult to grow? It will be positioned in a SW border.
