I got this cute little ground cover last Fall at Matilija Nursery out in Moorpark. It's worth a visit. The plant has been flowering since I got it. I am not kidding! What a fabulous plant! It's a Western US native called Calylophus berlanderiera or Sundrops. I can never remember what it's called and always have to look it up. It was in a 1 gal. can and is now 2' across. Here it is in my garden next to my bottle border and a Mum, an Iris and a Narcissus. Research says it will grow up to 1' tall and 3' wide. It likes full sun and well drained soil. It must love my sandy soil.
And I just had to share a pic of me in my new Matilija t-shirt! What a great design and I love the mint green shirt color! Thanks Bob!
