Recommended Temperature Zone: sunset: 5-24, 28-31 USDA: 8-10 Frost Tolerance: Hardy to 10°F (-12°C) Sun Exposure: Light shade to shade Origin: Southern Europe Growth Habits: Evergreen trailing perennial to 10 inches tall (22.5 cm), can become invasive Watering Needs: Fairly drought resistant, fast grower with regular water Propagation: grows roots whenever a stem touches the ground

This plant may become weedy or invasive in some regions or habitats and may displace desirable vegetation if not properly managed.

The species name "minor" comes from the Latine for "smaller".

Cultural Practices:
Common periwinkle is adapted to mild climates. It usually requires part shade and ample moisture, but will tolerate full sun if it is adequately watered. It is more hardy than big leaf periwinkle. Moisture and exposure are often more restrictive than soil type on determining adaptation.

Common periwinkle is adapted to a wide range of soils. It is found on well drained to poorly drained soils that can be calcareous, alkaline to slightly acidic, and medium textured to fine textured. The plant should be used where there is adequate moisture.

Blooming Habits:
Small blue flowers occur indeterminately from April to September. Blooms better with more sun.

Propagation:
Plants may be established from rooted cuttings produced in flats or from plant division. Plant on a spacing of 18 inches x 18 inches. Fertilizer should be applied for vigorous establishment. Mulch critical areas immediately after planting. Planting can be done any time of the year when moisture is adequate for establishment. This should ordinarily be planted on areas that can be sprinkled or otherwise irrigated or on sites where average annual precipitation is over 20 inches.

Common periwinkle can be affected by blight, canker, leaf spot, and root rot.
