I bought one lithodora last year and it lasted a week. The one I bought this year only lasted for 4 days. Every other plant in the same area is doing wonderfully.

Are you getting these plants from a reliable source? Sounds like they're coming to you with problems already. How does a plant die completely in four days? Could it have been something that happened to it before you bought it? Too bad you've had no luck because they're one of the few true blue flowers that we have. I posted a couple of pictures of mine that I took today on this forum in the "Show us your gardens" thread.

Did anyone else's Gelsemium 'Margarita' seem to bloom more profusely than
usual this year? Sure wish there was a way to effectively combine these two
plants. . .hmm. . .maybe the Gelsemium scrambling up a high wall, and then
the Lithodora cascading down from atop the wall. Now let me see: where can
I build an 8' wall in my garden? NOT!
