Gentian speedwell Veronica gentianoides 'Barbara Sherwood'

Water

Speedwell 'Barbara Sherwood' prefers consistently moist soil, so it should be watered regularly. Typically, it should be watered once a week, but this can vary depending on climate conditions such as temperature and humidity. During the growing season, ensure it receives about 1 inch of water per week, which equates to about 0.623 gallons per square yard of soil. In hot, dry periods, you may have to water more frequently, but always allow the soil to dry out slightly between waterings to prevent waterlogging. During winter, reduce the frequency of watering as the plant's growth slows down and it requires less moisture.

Light

Speedwell 'Barbara Sherwood' thrives best in full sun to partial shade. This means it should receive at least 4 to 6 hours of direct sunlight daily, with some protection during the hottest part of the day if grown in regions with very intense sunlight. A spot that enjoys morning sun with dappled afternoon shade or vice versa is ideal, ensuring the plant gets enough light without being scorched by the midday sun.

Temperature

Speedwell 'Barbara Sherwood' is cold-hardy and can withstand temperatures down to about -30°F, making it suitable for many temperate climates. The ideal temperature range for this perennial is between 60°F and 75°F, which promotes healthy growth and flowering. While this hardy plant can survive temperature extremes, it's best to protect it from harsh winter winds and extreme summer heat above 85°F to maintain its vitality.

Pruning

Speedwell 'Barbara Sherwood' should be pruned to maintain its shape and encourage bushier growth. Deadheading, or removing spent flowers, will promote a longer blooming period. Pruning should be done in early spring or after flowering, cutting back the plant by about one third to stimulate new growth. Additionally, older foliage can be removed in the spring to make way for fresh leaves.

Cleaning

As needed

Soil

Gentian Speedwell thrives in well-draining soil with a pH range of slightly acidic to neutral (pH 6.0-7.0). A mix with equal parts garden soil, compost, and coarse sand or perlite will create a conducive environment for root health and growth.

Repotting

Gentian Speedwell does not require frequent repotting and can typically be repotted every 2 to 3 years. Choose a pot only slightly larger than the previous to avoid excessively damp soil, which can lead to root rot.

Humidity & Misting

Gentian Speedwell prefers moderate humidity levels and can adapt to the humidity found in most outdoor garden environments without needing any special adjustments.

Suitable locations

• Indoor

  Place in bright, indirect light and ensure pot has drainage.

• Outdoor

  Plant in full sun to partial shade; mulch and moderate watering.

• Hardiness zone

  4-8 USDA

Life cycle

Veronica gentianoides 'Barbara Sherwood', commonly known as Gentian Speedwell, begins its life cycle as a seed, typically planted in well-draining soil in early spring or fall. Upon germination, the seedling emerges and develops into a vegetative stage characterized by a low-growing rosette of oval leaves. As the plant matures, it enters the flowering stage, usually in late spring to early summer, producing delicate blue to violet flowers with white centers on erect stems. After pollination by insects, the flowers develop into capsules containing numerous small seeds. Once mature, the seed capsules release the seeds, completing the reproductive cycle of the plant. In colder climates, Gentian Speedwell may die back to the ground in winter, but it is a perennial and will regrow from its rootstock when conditions become favorable in spring.

Propogation

• Propogation time

  Spring to summer

• Veronica gentianoides 'Barbara Sherwood', commonly known as Speedwell, is typically propagated by division, which is one of the most popular methods for multiplying this perennial plant. The best time to undertake division is in the spring or early fall. To propagate by division, carefully lift the parent plant from the ground and using a sharp knife or spade, divide the plant into smaller sections, ensuring that each section has a good amount of root and a few shoots. Replant the divisions promptly into well-prepared soil, maintaining the same depth as they were originally growing. Water them thoroughly to help establish the roots in their new location. This straightforward method fosters healthy new plants that will start flourishing right away and often bloom within the same growing season.
