Does it spread?
It is less vigorous than the plain green sweet flag and easy to keep in check, but divide it every few years to keep clumps healthy.
How to plant and care for it
Plant in an aquatic basket in spring or summer in full sun. Cut back old leaves in autumn. Watch for powdery mildew in dry spells.
Is it poisonous?
Yes. Like the green form, it contains toxic beta-asarone and should not be eaten.
