Asian virginsbower: complete guide

Overview

Clematis florida, commonly known as Asian virginsbower or Florida clematis, is a graceful climbing vine originating from South China. This member of the Ranunculaceae (buttercup family) distinguishes itself with elegant, fully double flowers featuring prominent staminodia (inner petal-like structures) in the center.

This climber is quintessentially elegant and ornamental, typically reaching 3-5 meters in ideal conditions. It is popular with flower enthusiasts for its refined blooms and extended flowering period from May through October.

Appearance & Bloom

Clematis florida produces elegant, largely double flowers of 5-10 centimeters diameter. The primary petals are white to pale green, with striking central staminodes in purple-red to dark purple. This color contrast makes each bloom a work of art.

Flowers appear in June and continue into October, with multiple flowering waves throughout the season. They are pleasantly lightly fragrant. The seeds develop feathery tails that are also decorative.

Ideal Location

Clematis florida grows best with warm, sheltered microclimate. In warm-temperate climates (zones 8-10), it thrives against south or west-facing walls. In cooler climates, it can be grown in a greenhouse or against very heated walls. The plant needs 5-6+ hours direct sunlight for optimal flowering.

Roots must have shade - plant other low-growing plants at the base to keep roots cool.

Soil

Clematis florida prefers well-draining, nutrient-rich soil with pH 6.5-7.5. It cannot survive waterlogged ground. Work generous amounts of compost or rotted manure into planting holes, and provide slow-release fertilizer during the growing season.

Heavy clay soils must be amended with sand and compost for proper drainage.

Watering

Once established, this clematis is fairly drought-tolerant, though regular watering stimulates flower production. Water deeply and regularly during the growing season (May-October), but ensure drainage is perfect.

In very hot, dry summers, daily watering may be necessary. Mulch around the plant base with 5 centimeters of compost for moisture retention.

Pruning

Clematis florida belongs to "group 2" clematis (pruning to prevent congestion). After flowering (October-November), cut back to approximately 50 centimeters height to maintain shape and encourage density. Remove dead or diseased tissue.

In early spring (March), you can prune lightly to refine shape, but avoid heavy pruning.

Maintenance Calendar

March-April: Light pruning for shape; fertilizer application. May-June: First flowering period; regular watering; support/training work. July-August: Second flowering period; water support; deadheading for more blooms. September-October: Third flowering period; reduce watering toward month-end. November-February: Heavy pruning; winter dormancy.

Winter Hardiness

Clematis florida is not fully winter-hardy in temperate climates. It is recognized as USDA zones 8-10 plant (to about -7 to -12 degrees Celsius). In zone 7 or colder, it must grow against a very protected south-facing wall or even in a greenhouse. In the Netherlands and Belgium, it does not overwinter outdoors without protection.

Companion Plants

Companion plants for Clematis florida:

• Solanum (ornamental): yellow to orange fruits give contrast
• Forsythia: yellow spring bloomers give supporting color
• Rosa: pink or red climbers combine gracefully
• Jasminum: white night-blooming jasmine combines with light

Closing Thoughts
