Iris ‘Tropic Night’

Velvety, violet flowers with veined yellow throats appear in May and June among bright green, slender, strappy leaves. Like all Siberian flag irises, this is a clump forming plant that needs space to spread out and prefers a moist, neutral to slightly acid soil in sun or partial shade. It looks best planted in bold drifts beside water and allowed to naturalise. It is particularly useful on difficult banks where it will help to prevent erosion and over time will form large clumps. It can also be planted in a pot as a marginal plant for a pond.
