'Rozanne' Geranium I fell in love with this plant at first sight. It offers gorgeous lavender-blue flowers from early summer all the way to frost, attractive variegated foliage, and it's a cinch to care for. 'Rozanne' is definitely a winner! Name: Geranium 'Rozanne' Size To 1 foot tall and 3 feet wide Zones: 5-9 Plant it with: White shrub roses, yellow coreopsis, or perennial hibiscus
Geranium - This is not your typical annual geranium that fills window boxes everywhere… in truth, those are Pelargoniums. True geraniums are a perennial that does well in partial shade, and blooms pink or blue all summer. In addition, many varieties’ foliage turns bronze or red in the fall. We love Geranium “Rozanne”. Its blooms are big and blue, and the plant grows to 20 inches.
Cranesbill, aka Perennial Geranium - This pretty, flowering plant comes in pinks and blues, and realm when cut back after blooming. They love partial shade, but will grow in deeper shade. Rich soil and regular fertilizer, regular water and room to spread 24-36 inches per plant, depending on the variety. Some varieties grow close to the ground, and others to 3 feet tall.
