Hardy Geraniums (Cranesbill)

Hardy geraniums, also known as cranesbill geraniums, are a group of perennials under the Geranium genus. Not to be confused with the annual geraniums of the Pelargonium genus, these plants are known for their toughness, vigor, and extended flowering period.

Habit: Ranging from tiny alpine geraniums to large, bushy varieties, hardy geraniums display a wide variety of growth habits. Typically, they form low mounds or trailing forms, with heights ranging from 6 inches (15 cm) to several feet. They make excellent ground covers and can also thrive in containers and rock gardens.

Foliage: The foliage of hardy geraniums is broadly lobed to finely cut, often becoming vibrantly colored in autumn. The leaves offer a beautiful backdrop to the delicate, saucer-shaped, five-petaled flowers that bloom from spring to fall.

Flower: Flower colors span from white, pink, and purple, to blue, and certain varieties showcase intriguing veining or a contrasting center. Most bloom profusely over a very long season, extending from spring to late fall (if cut back hard after the first flush of blooms starts to fade in early summer).

Hardiness: Hardy geraniums are robust plants, adaptable to a wide range of conditions. They are typically hardy in USDA zones 4-8, with some varieties tolerating colder or warmer conditions.

Culture: Plant hardy geraniums in a location that receives full sun to partial shade, depending on the variety. Many geraniums appreciate some afternoon shade in hot summer climates to prevent leaf scorching. While they prefer well-drained, moderately fertile soil, they can tolerate a variety of soil types, including clay, loamy, or sandy soils. Some can even tolerate periods of drought once established.

These perennials provide excellent value in the garden, offering long-lasting floral displays, attractive foliage, and a robust nature. Some species even display good resistance to rabbits and deer. Whether as a border plant, in rock gardens, or cascading over walls, hardy geraniums can add beauty and resilience to various garden settings.

There is a broad array of colors and textures to choose from. If you are looking for a beautiful, low-maintenance, hardy geranium that will sail through the challenges of the seasons, you may want to review these guides.
