|For the second year, I am having trouble growing Cupid's Dart from seed. I get what look like healthly, small plants with the long skinny green leaves, but they don't seem to take off after that. Only one of the seedlings I started last year has survived to this year, but it never got big or bloomed. I cannot find much in my books about its soil and water needs. Before I moved this year's seedlings from the pots to the garden, I thought I'd check with you. (I have had success with other seedlings. And I don't find anything specific about Cupid's Dart in the NGA library, although I did find a lovely list there of other blue flowering plants--thanks!)
|Catanache caerulea is usually considered an easy plant to grow, but it does require full sun. A hot sunny spot on the dry side suits it perfectly. It kicks into growth when the weather and soil warm up, and will self sow where it is happy. Some sources suggest a sandy soil, but a well drained soil should be adequate. If you have a heavier clay soil, that might explain the problem.
