Johnson's Blue Geraniums

Geranium himalayense x pratense


Johnson’s Blue is a hybrid of Geranium himalayense, a native of China. It happily weaves between other plants, pumping out cheery periwinkle blossoms for weeks on end. It makes a good ground cover and border perennial. Easy to grow, it is a good choice for beginning gardeners. As an added bonus, it attracts bees and butterflies.


Plant the crown, the place where the shoots and the roots meet, level with the soil surface and 12-18” apart in a sunny location. Plant with the roots horizontal in the soil. Water well. Although Johnson’s Blue is drought tolerant, it prefers well-drained soil.


Cut the flower stems and any rough-looking foliage to the ground after flowering to encourage plants to produce fresh foliage. Beginning in the second year, plants often produce a second flush of flowers later in the season, especially if they are cut back after the first flowering.


Johnsons’ Blue is quite hardy and will overwinter well, except in the coldest areas. Lay down a 2” layer of mulch to retain moisture and provide protection during the winter months, especially in zone 4. The foliage will turn beautiful shades of orange and red in the autumn.
