Iris missouriensis

Plant Details:

Plant Type: Perennial
Plant Family: Iridaceae
Plant Description: A variable, beardless iris with narrow leaves to 20 inches, overtopping the flowers. Each branched stem bears 2-4 flowers 2.5-3 in. across. Blossoms are pale to deep blue or lilac/purple having larger falls with deep purple veining. Blooms from May-June. Best grown in full sun and well drained, slightly acidic soil.

Maintenance:

Maintenance Type: Perennial - Herbaceous
Plant Care: Perennial - Herbaceous (soft-stemmed plants that die back in winter and regrow in spring): Remove spent blooms to promote rebloom later. Some plants tend to flop over after the first bloom and attempt to regrow from the base; in these cases, the old stems can be cut away in summer. As plants become dormant in the fall, remove dead leaves and stems.
