Virginia Dayflower: A Charming Native Groundcover for Shady Spots
Looking for a delightful native plant that thrives in those tricky shady, moist spots in your garden? Meet the Virginia dayflower (Commelina virginica), a charming perennial that might just become your new favorite groundcover. With its distinctive blue flowers and easy-going nature, this native gem deserves a spot in every wildlife-friendly garden.
What Makes Virginia Dayflower Special
Virginia dayflower is a native perennial forb that produces lovely blue flowers throughout the summer and fall. True to its common name, each flower typically lasts just one day, but the plant keeps producing new blooms over an extended period. The flowers are uniquely structured with two prominent blue petals and one smaller, less conspicuous petal, creating an asymmetrical but appealing appearance.
This native beauty reaches about 3.5 feet in height and spreads via underground rhizomes, making it an excellent choice for naturalizing larger areas. The heart-shaped leaves are medium green and create a lush, tropical-looking backdrop for the bright blue blooms.
Where Virginia Dayflower Calls Home
As a true native of North America, Virginia dayflower naturally occurs across much of the eastern and southeastern United States. You’ll find it growing wild in Alabama, Arkansas, Delaware, District of Columbia, Florida, Georgia, Illinois, Indiana, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, West Virginia, and Puerto Rico.
Perfect Spots for Virginia Dayflower in Your Garden
Virginia dayflower shines in several garden settings:
- Woodland gardens: Its shade tolerance makes it perfect for naturalizing under trees
- Rain gardens: Thanks to its facultative wetland status in most regions, it handles both wet and moderately dry conditions
- Native plant gardens: Adds authentic local character and supports regional ecosystems
- Naturalized areas: Excellent for low-maintenance, wild-looking spaces
- Groundcover applications: Spreads nicely to fill in bare spots
Growing Conditions That Make Virginia Dayflower Happy
One of the best things about Virginia dayflower is how adaptable it is to different moisture levels. Here’s what this easy-going native prefers:
- Light: Partial to full shade (it’s quite shade tolerant!)
- Soil: Adapts to fine and medium-textured soils with medium to high fertility
- pH: Prefers slightly acidic to neutral soils (4.7-6.7)
- Moisture: Medium moisture needs, though drought tolerance is low
- Hardiness: Thrives in USDA zones 5-10
The plant requires at least 165 frost-free days and can handle minimum temperatures down to -18°F, making it suitable for a wide range of climates.
Planting and Care Made Simple
Virginia dayflower is refreshingly low-maintenance once established. Here’s how to get started:
- Planting: Best grown from container plants or seeds (about 175,000 seeds per pound!)
- Timing: Plant in spring after the last frost
- Spacing: Allow room for spreading – plant 2,700-4,800 plants per acre for larger areas
- Establishment: Water regularly during the first season; seedling vigor starts low but improves
- Maintenance: Very little needed! The plant has a long lifespan and moderate growth rate
Keep in mind that this plant spreads rapidly through underground rhizomes, so give it space to roam or be prepared to manage its spread in smaller gardens.
Wildlife and Pollinator Benefits
Virginia dayflower isn’t just pretty – it’s also a valuable wildlife plant. The morning blooms attract bees and other small pollinators, providing nectar during the summer and fall blooming period. Large animals occasionally browse on the foliage, though it typically makes up only 5-10% of their diet.
The plant produces red seeds that add a subtle splash of color in fall, though they’re not particularly showy. These seeds help ensure the next generation of plants while providing some food value for wildlife.
