Can it grow in water?
Yes. Louisiana irises like reliably damp to wet soil and grow at pond margins. No depth has been published for 'Heather Stream' itself; 0–10 cm of water is the figure given for other Louisiana irises.
How to plant and care for it
Plant in damp, organic-rich soil in full sun or part shade. Watch for slugs, snails, thrips and grey mould.
Is it poisonous?
Yes. Irises are harmful if eaten by people or pets, so wear gloves when handling it.
Which size should I buy?
Bare-root plants (7 cm, 9 cm, 1 litre and 3 litre) arrive without a pot or compost and are the most economical way to plant a group. Potted plants (9 cm, 1 litre and 3 litre) arrive growing in our peat-free compost and give a faster display. Packs of 3 come in 7 cm, 9 cm, 1 litre and 3 litre bare-root sizes and cost less per plant. The 2x Pot & Compost option is two plants supplied with pots and compost.
