Product Description
Iris pseudata 'Kimboshi' - Pseudata Iris, Pond Marginal Plant
Iris 'Kimboshi', sold as Iris × pseudata 'Kimboshi', is a pseudata iris: a hybrid between the yellow flag (Iris pseudacorus) and the Japanese iris (Iris ensata), bred by Hisaharu Ueki. Its name means 'golden hat'. Early in the iris season it carries pale yellow flowers with a dark yellow signal patch and fine brown lines, above upright, sword-shaped leaves.

Can it grow in water?
Yes. Plant Delights says it can grow as a marginal aquatic, as well as in damp to wet soil, including heavy wet clay. UK and US aquatic nurseries give up to 10 cm of water over the crown.
Will it spread like yellow flag?
No. It is sterile and sets no seed, so unlike its parent, the yellow flag, it will not seed around. Plant Delights says it is not a weed risk.
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.
