Planting
From Early Spring TO Mid Spring
These plants have a long tap-root, and because if this they don't transplant easily. The best chance of a survival rate when transplanting is to do it in Spring. Generally speaking, though, it is better to sow in situ, to avoid the need to transplant. Sow in a sunny sheltered site.
Propagating by seed
From Early Spring TO Mid Spring
Sow in Spring in situ - in a sunny, sheltered site. The seeds can be sown in Autumn, but need a chilling period first (three weeks or so in the fridge would suffice)
Flowering
From Early Summer TO Late Summer
Milkweed - both the leaves and flowers -is the food source for monarch butterflies, and as such is an important plant for anyone interested in supporting the monarch butterfly population. The flowers appear in Summer
