But you may want it even if you are not that into the "weird" (I am), because it is a preferred food source of the Pipevine Swallowtail Butterfly. It's said to attract them. Arrowhead Alpines, who sell the plant, note, "One of the high points of last summer was sitting around talking ferns with Dr. Storer, only to have him spot a 5th instar Papilio (Battus) philenor larva come crawling by, an event so unlikely that at first I thought it a joke. I've collected for years and never seen it in this part of Michigan; I figured Herb Wagner must have given him a larva or something. When I went to the garden to find it something to munch on there they were, 1.5” purple black, with magnificent fleshy tentacles like something out of the rainforest, devouring my Aristolochia ... read more |

Pre-soak stored seed for 48 hours in hand-hot water and surface sow in a greenhouse. Germination usually takes place within 1 - 3 months at 20°c. Stored seed germinates better if it is given 3 months cold stratification at 5°c. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant out in late spring or early summer after the last expected frosts. Division in autumn. Root cuttings in winter. |
