- Some species are grown in gardens for their bright, annual blooms.
- Clarkia supports native pollinators, including bees that rely on it exclusively.
What does Clarkia look like?
Clarkia plants are annual herbs that can grow upright or spread along the ground, reaching up to about 2 metres tall depending on the species. Their leaves are simple and small, between 1 and 10 cm long. The flowers have four petals and four sepals, with petals that are usually white, pink, or red, and often marked with spots or streaks. After flowering, they produce long, grooved seed pods filled with tiny, cube-shaped seeds.
Where does Clarkia come from?
Nearly all Clarkia species are native to western North America, with one species, Clarkia tenella, found in South America. The genus was named after Captain William Clark, known from the Lewis and Clark Expedition. Some species were once placed in a separate genus called Godetia, but this is no longer used in modern classification. Clarkia species have long been part of their native habitats and are important for local pollinators.
When and how Clarkia blooms
Clarkia species are grown as annuals, meaning they complete their life cycle in one year. They are usually started from seed, sown directly into the soil. The plants thrive in well-drained soil and sunny locations. Gardeners often grow species like Clarkia unguiculata and Clarkia amoena for their colourful flowers, which bloom in late spring or early summer.
How Clarkia is used
Several Clarkia species are popular in gardens for their bright, showy flowers. They are valued for adding colour to flower beds and borders. In the wild, Clarkia flowers provide food and habitat for native bees and caterpillars, making them important for supporting local ecosystems. Some pollinators, such as the clarkia bee, depend on these flowers.
Kinds of Clarkia
The genus includes over 40 species, with some of the best-known being Clarkia unguiculata (mountain garland), Clarkia amoena (farewell to spring), Clarkia speciosa (redspot clarkia), and Clarkia bottae. Cultivated varieties have been developed for gardens, offering a range of flower colours and forms.
What Clarkia means
