    Asclepias tuberosa - Butterflyweed

    SKU: C11580



    One of the most striking of all wildflowers, the brilliant orange flowers of the Butterflyweed appear in mid-summer and are a real magnet for butterflies. Reaching up to three feet tall, this is one of the last plants to come up in the spring as it requires warm soil conditions before it will grow. Butterflyweed is fantastic in borders paired with Prairie Dropseed or Little Bluestem. Start some Asclepias tuberosa seeds this year to attract butterflies to your garden!

    Indoors: Cold, moist stratification. Start at least 5 weeks before outdoor night temperatures are reliably in the 10 C (50 F) range. Mix the seed with a slightly moistened, sterile, soil-less growing mix. Put this in a labelled, sealed plastic bag and store in a refrigerator for one day. The next day place this in the freezer for one day. Repeat this for one week, alternating between the fridge and the freezer. After stratifying, plant seed 0.64 cm (1/4 inch) deep in pots. Keep moist but not soggy and very warm (21 C - 70 F). When seedlings are 5 cm (2 inches) tall or more, transplant into the garden spaced 30 cm (1 foot) apart.

    Outdoors: Plant seed 0.64 cm (1/4 inch) deep in a prepared seed bed in late fall so that the seed overwinters and germinates naturally in spring.

    Outdoors Alternative: In late fall through to mid-winter fill plastic pots with a slightly moistened, sterile, soil-less growing mix. Plant seed 0.64 cm (1/4 inch) deep in pots and label the pots. Place them outdoors in an area where they will experience the snow and cold of winter. The seed will germinate in the pots in spring as the weather warms up. Be sure to water the pots regularly in spring and once the plants are 5 cm (2 inches) tall, transplant them into your garden.
