Growing Information
How to plant:

Propagate by seed, division or separation - Seed germinates best at 70 F to 75 F in humid conditions. Will self-seed under favorable conditions.

Divide in spring or fall, separating new plantlets from the crown.

Maintenance and care:
Keep soil moist but not soggy.

Cut flower stems back to lateral bud when stalks begins to fade, then cut flower stem off entirely down to basal rosette after blooming has ceased.

Pinched plants will not develop large flower spike, but will produce several smaller ones that aren't nearly as spectacular.
