The clump forming Iris germanica ‘White Knight’ have ruffled white flowers with white falls and yellow beards. The upright petals have a different colour than the drooping petals. This gives a nice colour contrast within one flower. On the lower petals is the so-called ‘beard’. That is why these Irises are also called ‘Bearded Iris’. These stunning flowers bloom May to June and gain a height up to 50cm. Iris germanica ‘White Knight’ is a hardy perennial and grows well in the garden, pots, and can be used in indoor flower arrangments . The plant has thick rhizomes. These thick roots should be planted shallowly and almost horizontally as soon as possible after receipt. First loosen the soil well. Improve heavy garden soil by mixing in sharp sand. Make a mound in the planting hole. Place the thick rhizomes of the bearded Irises about 1 cm below ground level on the knoll. Fill the planting hole with soil and press firmly. Water immediately after planting. The planting distance is approx. 25-30 cm. These Irises grow and flower well in full sun or partial shade in well-drained, fairly dry soil. The sword-shaped, grey-green leaves die off at the end of summer, but new leaves appear in the fall. In winter, cover the plants with a layer of fallen leaves or some branches. Cut off all the leaves in the spring. Soon new shoots will appear above the ground.
