Geranium JOHNSON BLUE (BAREROOT) ‘
Johnson’s Blue’ is one of the most popular blue-flowered geraniums. It first appeared in English gardens in the 1950s. It is reportedly a hybrid between G. himalayense and G. pretense. It is a rhizomatous perennial that typically grows in a dense spreading mound to 12-18” tall and to 24-30” wide. Large, saucer-shaped, sky blue flowers (to 2” diameter) bloom in clusters (cymes) above the foliage from late spring to early fall. Deeply cut dark green foliage.
Hardy and will grow in most areas of the United States. Listed as hardy in zones 3-10, it will tolerate the dry heat of the southwest but does not like the humid heat of the southeast. Some hardy Geraniums are also notorious self-seeders, but Magnificum is a sterile hybrid that will grow only where you plant it.
Planting Instructions: Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. Propagated by seeds and division of roots. Should be transplanted from the seedbed in early spring. Prefers full sun and well-drained soil.
