Planting:

Plant in a 5- to 6-inch pot to allow the roots to continue to develop and place in a sunny window for about a month. Water once every 5 to 7 days to keep the soil damp but not overly wet. Young plants that are not well rooted can be easily over watered, which can cause root rot and death.

After about a month, transplant into a larger container (10 to 15 inches in diameter) and place in full sun or plant into the garden, 3 to 6 feet apart in a moist to boggy soil that contains plenty of organic matter. Water every 3 to 4 days to keep the soil damp. Larger plants (especially those in pots) may need to be watered daily in hot areas.


Maintenance:

In the colder half of zone 7, small plants are best moved indoors for the first winter; larger plants should be mulched heavily with pine needles, salt marsh hay, or shredded leaves.

In areas north of zone 7 where it is not hardy, move indoors to a bright room in the fall and grow as a houseplant. If space is not available, it can also be cut back close to the soil line and stored as a dormant plant in a cool, dark basement. Check the soil every 4 to 5 weeks to keep it barely damp.


Zones:

Zones 7-10
