'Blue'
Geranium
Geranium 'Johnson's Blue' is a classic hardy geranium known for its abundant sky-blue, saucer-shaped flowers that bloom from late spring to midsummer. Its finely cut, deep green foliage forms a dense, spreading mound that remains attractive throughout the growing season, turning red and gold in fall. This vigorous perennial thrives in full sun to part shade and adapts well to various soil conditions, showing drought tolerance once established. Resistant to deer and rabbits, it is ideal for borders, cottage gardens, and ground cover, providing reliable color and texture with minimal maintenance.
