This full sun collection is curated with 5 wildflower varieties that are beneficial to monarch butterflies. Common, Butterfly, Showy and Swamp Milkweed are the host plant of the monarch butterfly caterpillar, while Dense Blazingstar is a favourite nectar source for adult butterflies.
Note: all varieties in this collection require moist stratification. See instructions below. For those interested in seed saving, also note that Showy Milkweed will hybridize with Common Milkweed. In order to produce seed that is true to parent, it is necessary to plant these varieties a sufficient distance apart (2,500 feet or more).
Cold, moist stratification required. Mix seeds with moist substrate (vermiculite, perlite or moss) and place in a plastic bag and refrigerate for 6-8 weeks. Sow seed at 1/8 inch depth. Do not let seedling dry out while it is establishing.
Sow directly outdoors in late fall to overwinter.
