This listing is for 4 Ludwigia alternifolia, Rattlebox Pods. These pods have a lot of tiny seeds in them so 4 pods is more than enough to get you started. The plant is beautiful through summer, and again when the pedals fall revealing a pretty red calyx. Then, the seed box is something everyone should see. What a strange looking cubical seed pod with a single little hole on top for dispersal. There isn't much information on this wild native in terms of uses as of yet. Though its known the Rattlebox are a host plant for the banded sphinx moth (Eumorpha fasciatus). Good gift for your Lepidoptera gardeners. Thank you for looking!
