Evolvulus

Description

Evolvulus is a genus of flowering plants in the family Convolvulaceae. It consists of around 100 species that are native to tropical and subtropical regions, primarily in the Americas. The most commonly cultivated species is Evolvulus glomeratus, also known as blue daze or Hawaiian blue eyes.

Taxonomic Information

Appearance

Evolvulus plants are known for their attractive, small, funnel-shaped flowers that come in shades of blue, lavender, and white. The leaves are small, simple, and alternate, with a slightly hairy texture. The plant grows in a low, spreading mound, and typically reaches a height of 6-12 inches. Blue daze, in particular, is a popular ornamental plant that is often used as ground cover.

Care Guide

Evolvulus plants are relatively easy to care for, making them a great choice for both novice and experienced gardeners. Here are some tips for keeping your Evolvulus healthy and thriving:

Water: Evolvulus plants prefer consistently moist soil, but be careful not to overwater them, as this can lead to root rot. Water deeply once a week, or more frequently during hot, dry weather.

Fertilization: Feed your plant with a balanced, all-purpose fertilizer once a month during the growing season. Avoid fertilizing during the winter months when the plant is dormant.

Soil: Evolvulus thrives in well-draining soil that is rich in organic matter. A mix of peat moss, sand, and perlite is ideal.

Sunlight: Evolvulus prefers full sun but can tolerate partial shade. Make sure the plant gets at least 6 hours of direct sunlight per day.

Hardiness Zones: Evolvulus is hardy in USDA zones 8-11, but can be grown as an annual in cooler climates.

Common Pests & Diseases

Evolvulus plants are generally resistant to pests and diseases. However, they can occasionally be affected by spider mites, aphids, and whiteflies. To prevent these pests, keep your plant well-watered and avoid over-fertilizing. If you do notice an infestation, treat the plant with an insecticidal soap spray.

Habitat

Evolvulus plants are native to tropical and subtropical regions, primarily in the Americas. They are commonly found in open, sunny areas, such as fields and roadsides. Blue daze, in particular, is native to Brazil and Paraguay.
