Wow, those are some very cool plants! I don't have any semps at all. I keep intending to branch out and venture into some new types of plants, but then fall hits, and I panic at the thought of winter, and plant a ton more spring bulbs and iris rhizomes.
I can't tell you the horror I felt when I first read The Lion, the Witch, and the Wardrobe, and they said that the White Witch made it be always winter, but never Christmas. I live for spring!
