Jewelled Crown is a Siberian iris with rich, contrasting color. Its 3 to 5-inch flowers are wine purple, with lighter blue-purple style arms and semi-flaring falls marked by white and yellow signals and purple veins.
Plants grow 28 to 34 inches tall with narrow, disease-resistant foliage that looks good all season. It is especially pretty massed around ponds and water features, and it makes a fine cut flower.
What it looks like
Flowers 3 to 5 inches across with rich wine-purple standards and semi-flaring falls, lighter blue-purple style arms in the center, and prominent white and yellow signals on the falls lined with purple veining. Flowers are held on slender, upright stems above narrow, grass-like green leaves. The plant forms an upright clump about 28 to 34 inches tall and 18 to 24 inches wide. At peak the dark wine flowers with bright centers stand out sharply above the foliage.
Growing it with lavender
Siberian iris prefers steadier moisture than lavender, so it fits best in a moister border or rain garden nearby, where its early-summer blooms can open just before the lavender begins.
Care
Grow in full sun to part shade in average to rich soil and keep it well watered through the season, especially in spring and early summer. Hardy in zones 3-9. Cut back the foliage in late fall or early spring, and divide crowded clumps in late summer; Siberian iris is not bothered by black walnut.
