Ask the Expert: An annual flower
I grow a twining plant, an annual, the has a very thin stem, with soft feathery leaves shaped like individual pine needles, and very small magenta star shaped flowers. The seeds are small and individual with each flower, black and about the size of coursely ground pepper. I saw it at the Missouri Botanical garden, but it was mislabled as penta lanceolata. The plant grows up to 15 feet up the side of the greenhouse, and reseeds readily. Gail
