The hardy perennial geranium is a good ground cover plant with many varieties to choose from. Do not confuse hardy Geraniums with Pelargoniums which are also sometimes referred to incorrectly as Geraniums.
Geraniums are one of the easiest and most versatile low growing plants. They are not fussy, but given a reasonable level of care they will reward the gardener with ground cover and 1 or 2 extended flowering periods.
Care for Geraniums
- After flowering cut back geraniums to their base. Feed and water and you will get a second flush of leaves and flowers later in the year.
- Geraniums are easy to divide. It is best done after the growing season is over in October. Just use a spade and divide their crown into two or three. If cut back, Geraniums can be divided at any time of they year but they will need more attention with watering.
- Geraniums grow best in full sun or partial shade but they are versatile and in our experience not that fussy.
- The great thing about Geraniums is that the mature plants seem relatively resistant to the most common pests – slugs and aphids. However, plug plants will need the usual protection from slugs and snails.

G. Johnsons Blue pictured is a strain of G. pratense and is a strong growing, self spreading plant. Mrs Kendall Clark is another clear blue but Rozanne has a longer flowering period from early summer to late autumn.
A pink geranium G. sanguenium is commonly found in many cottage gardens with it profuse pink flowers that have two flushes if cut back after the initial show. G Anna Folkard with lime green leaves has a trailing habit and needs some control in my garden.
Along with Johnsons Blue and Anna Folkard, Kashmir White has an Award of Garden Merit but I recommend you see plants in flower if you are looking to acquire it for a special colour or habit so that you make sure you are getting a good base stock that is worth the AGM.
The black Mourning Widow G. Phaeum like shade and self seeds profusely. My stock is also a weedy short lived flowering example that I am trying to throw out.
Greanium renardii has sage green leaves and delicately purple-veined flowers.
Geranium himalayense ‘Birch Double’ is vigorous and versatile. this superb cranesbill tolerates almost any situation; even full shade. A mass of double purple-pink blooms stand above the delicately serrated foliage which turns to shades of burnt red and orange in autumn. will quickly blend with other herbaceous perennials to create colourful groundcover and looks equally attractive in herbaceous borders and shady woodland gardens. Height: 25cm (10”). Spread: 60cm (24”).
Geranium wallichianum ‘Sweet Heidi’ have rich purple, cup shaped blooms with clean, white centres that are decorated with distinct maroon veining. Forming loose mounds of attractive lobed foliage, this robust hardy geranium makes excellent ground cover through the front of informal borders
