Geranium (Cranesbill) 'Johnson's Blue'
Rhizomatous, spreading herbaceous perennial, forming a dense mat of 7-lobed, mid-green, basal leaves, 2-8 inches long, each lobe itself lobed and toothed. Saucer shaped vivid blue flowers, 2 inches across, tinged pink at the centers, are produced in loose cymes during summer. Generally long-lived, versatile, and undemanding plants. Spring and early summer bloomer. Winter hardy and shows good tolerance to drought. Excellent for a weed smothering groundcover. Minimal care and free from pests and diseases.

CULTIVATION: Grow in humus rich, sharpley drained soil in full sun. Remove flowered stems and old leaves to encourage fresh leaves and flowers. May cease flowering during the heat of summer.
PROPAGATION: Divide in spring. Increase by basal cuttings, taken early or mid-spring, and root with bottom heat.
PESTS AND DISEASES: Prone to bacterial blight, downy mildew, powdery mildew, gray mold, and leaf spot in most locations. Leaf miners, slugs, and other pests of pelargoniums can be problems.
