Lobelia pedunculata, commonly known as matted pratia, trailing pratia or blue star creeper, is a perennial herb from Australia.[1]
It has sky-blue starry flowers, and can spread by underground stolon. In a garden setting some gardeners have found its ability to spread to be a nuisance.[2] [3]
One variety, Lobelia pedunculata var. Almanda Blue, was found in Scott Creek Conservation Park in 2013 by John Wamsley. It has a dense weeping habit and small, female-only flowers.[4] Wamsley registered it as intellectual property under Australia's plant breeders' rights and as a US patent.[5] Clones of this plant are sold as garden plants, and royalties go toward preserving biodiversity in the park it was found in.[6]
