Geraniums and cranesbills are often used interchangeably, but there are some differences between the two. Geranium is a genus of flowering plants that includes both annual and perennial species, while cranesbill specifically refers to the perennial geraniums, which are also known as hardy geraniums.
One main difference between geraniums and cranesbills is their growth habit. Geraniums, including the popular annual geraniums (Pelargonium), are often grown as bedding plants or in containers. They have a more compact growth habit and are commonly used for their vibrant flowers and decorative foliage. On the other hand, cranesbills have a more natural and spreading growth habit, making them great groundcover plants.
Another difference lies in their botanical classification. Geraniums belong to the family Geraniaceae, while cranesbills are a specific group within the Geranium genus, known as Geranium macrorrhizum or Geranium sanguineum, among others. Cranesbills are often referred to as the “true geraniums” because they are the original wild species of the genus.
In terms of appearance, geraniums and cranesbills have some similarities but also some distinct features. Both have lobed leaves and produce flowers in various colors, including shades of pink, purple, white, and blue. However, cranesbills often have more delicate and intricate flowers, with a more natural and wildflower-like appearance.
One of the most notable differences between geraniums and cranesbills is their fruit. The fruit of cranesbills is long and slender, resembling the beak or bill of a crane, hence the name “cranesbill.” This fruit is actually the seed pod of the plant and is often used for dispersal.
In terms of care and cultivation, geraniums and cranesbills have similar requirements. They both prefer moderately fertile, well-draining soil and perform well in full sun to partial shade. However, cranesbills are generally more tolerant of different soil conditions and can thrive in drier and poorer soils compared to geraniums.
While geraniums and cranesbills are related, cranesbills are a specific group within the geranium genus, known for their perennial nature, spreading growth habit, and distinctive fruit. Geraniums, on the other hand, encompass both annual and perennial species and are commonly used for their showy flowers in garden beds and containers.
