Overwintering Persian Shield (Strobilanthes) in Zone 5

Overwintering Persian Shield (Strobilanthes) in Zone 5

A reader in Omaha (Zone 5) planted Persian Shields outdoors in a sheltered, sunny spot with deep snow drift. Asks if they survive winter or should be propagated.

Answer

Strobilanthes needs Zone 8–9. Will not survive Zone 5 winter outdoors.

Propagation

• Take several cuttings (not best time of year, so increase odds).
• Use rooting hormone + moist sand.
• Keep in sunniest window, water sparingly (dry side) all winter.

Good luck!
