Not only will you benefit from the natural beauty, but by growing milkweed, you will also be helping a very fragile butterfly species. Asclepias is a genus of herbaceous, perennial, flowering plants known as milkweeds, named for their latex, a milky substance containing cardiac glycosides termed cardenolides, exuded where cells are damaged. Silky white hairs attached to each seed facilitate wind dispersal. Choose insect-free seeds. Choose seeds from other bug-free milkweed plants. Emphasis is on theoretical and empirical work aimed at generalization and synthesis across taxa, systems and ecological disciplines. The seeds can also float on water. Laboratory studies, using methods developed by Sheldon and Burrows, revealed that seed trait variation can influence variation in a plant's dispersal profile. © 1987 Nordic Society Oikos It is very water repellent. Milkweed seeds can be collected from existing plants or purchased from commercial suppliers. The seeds have a crown of … Both laboratory and field results suggest that coma length variation is more strongly related to variation in seed dispersal than is seed mass. Request Permissions.
