Asclepias

Asclepias Growing Information

Asclepias
Tuberosa

Planting:

Set plants 12 to 15 inches apart. Choose a sunny location where the soil, which need not be particularly fertile, is well-drained. Plant the crown 2 to 4 inches deep.


Maintenance:

Asclepias is late to break dormancy in the spring, so take care not to remove it accidentally during cultivation. Because of its extensive taproot (which helps account for its drought-tolerance), avoid disturbing established plants. Newly set out plants may benefit from a winter mulch; otherwise no special care is needed.


Zones:

Zones 3 to 9
