The flowers are a blue-purple color with a funnel-shaped corolla and white or pale spots at the base. The plant blooms in the spring and summer.
Growth Conditions for Veronica chamaedrys L. subsp. chamaedrys
Veronica chamaedrys L. subsp. chamaedrys, commonly known as germander speedwell, is a herbaceous perennial plant that often grows in rocky and wooded areas throughout Europe and western Asia. It is often cultivated as a decorative plant in gardens and is also known for its medicinal properties.
Light Requirements
Germander speedwell plants prefer partial to full sunlight exposure, although they can also tolerate some shade. In winter, they require full sun to bloom. These plants need at least 6 hours of direct sunlight per day to grow and thrive.
Temperature Requirements
Germander speedwell plants prefer cool temperatures between 60°F and 70°F (15.5°C – 21°C) during the day and slightly lower temperatures at night. They can tolerate heat up to 85°F (29°C), but they prefer cooler temperatures. During winter, they can tolerate temperatures as low as -20°F (-28°C).
Soil Requirements
Germander speedwell plants require well-draining soil rich in nutrients. They prefer slightly acidic to neutral soil with a pH between 6.0 and 7.0. These plants can grow in various types of soil, including loamy, sandy, and clay soils. However, they will not tolerate wet or poorly-draining soils.
It is important to note that germander speedwell plants do not require frequent fertilization, but they do benefit from an annual application of balanced fertilizer in the spring.
Cultivation
Veronica chamaedrys L. subsp. chamaedrys, also known as Germander Speedwell, is a herbaceous perennial plant that prefers well-drained soil. It can be grown from seeds or root cuttings, and planting should be done in the spring or autumn.
The plant requires full to partial sun exposure and can tolerate moderate winds but not strong gusts. It can grow up to 30 centimeters tall and spread up to 45 centimeters wide.
Watering needs
Germander Speedwell requires moderate watering, usually once a week, but this may vary depending on the weather conditions and soil type. The plant prefers moist soil, but it should not be waterlogged as this can cause root rot.
If grown in a pot, ensure adequate drainage to prevent waterlogging, which can cause the plant to wither and die.
Fertilization
Germander Speedwell does not require regular fertilization, but it can benefit from a balanced fertilizer once a year in the spring. Organic fertilizer such as compost is ideal for this plant.
Over-fertilization can cause excessive growth, which can reduce the plant's resistance to diseases and pests.
Pruning
Pruning Germander Speedwell can help maintain a compact size, promote healthy growth, and prevent the plant from becoming too leggy. Pruning should be done in the spring or autumn.
Use clean and sharp pruning shears to remove dead and damaged stems, as well as to control its size. Avoid cutting the plant back too hard as this can cause stress and weaken the plant.
Propagation methods for Veronica chamaedrys L. subsp. chamaedrys plant
Veronica chamaedrys L. subsp. chamaedrys can be propagated through several methods, including:
Seed propagation
Seeds of Veronica chamaedrys L. subsp. chamaedrys can be sown in either spring or autumn. The seeds should be sown thinly on the surface of a well-drained compost and then covered lightly with additional soil mixture. Subsequently, water thoroughly and surrounding temperature should be about 15°C to 20°C. It's important to keep the soil damp and protect the seedlings from direct sunlight.
Division propagation
The plant can be propagated by division in late winter when the plant is dormant. Dig up the whole plant and then using a sharp knife, divide it into several sections, each having a few roots and shoots. Each section can be planted in a well-drained soil mixture separately.
Cuttings propagation
Another easy way to propagate Veronica chamaedrys L. subsp. chamaedrys is through softwood cuttings in early summer. Take healthy, non-flowering shoots and cut them to a length of about 5-7 cm, remove the bottom leaves, dip the stem into rooting compound, and plant it in a compost and perlite mixture. Keep the soil damp and make sure that the cutting is placed in a place that receives indirect sunlight.
Disease Management
Veronica chamaedrys L. subsp. chamaedrys is susceptible to several diseases, including:
- Powdery mildew: This disease is caused by fungi and appears as white or gray powdery growth on the leaves and stems. To manage powdery mildew, prune infected parts of the plant and dispose of them properly. Apply a fungicide to the remaining healthy parts of the plant.
- Leaf spot: This disease is caused by fungi and appears as brown or black spots on the leaves. To manage leaf spot, prune infected parts of the plant and dispose of them properly. Apply a fungicide to the remaining healthy parts of the plant.
- Canker: This disease is caused by fungi and appears as sunken, discolored areas on the stems. To manage canker, prune infected parts of the plant and dispose of them properly. Apply a fungicide to the remaining healthy parts of the plant.
Pest Management
Veronica chamaedrys L. subsp. chamaedrys is also susceptible to pests. Common pests that may affect this plant include:
- Aphids: These pests are small, soft-bodied insects that suck sap from the plant. To manage aphids, spray the plant with a strong jet of water to dislodge them. You may also apply insecticidal soap or neem oil.
- Spider mites: These pests are tiny arachnids that feed on the plant. They are difficult to see with the naked eye. To manage spider mites, spray the plant with a strong jet of water to dislodge them. You may also apply insecticidal soap or neem oil.
- Caterpillars: These pests are the larval stage of moths and butterflies. They feed on the leaves of the plant. To manage caterpillars, inspect the plant regularly for eggs and remove them. You may also apply Bacillus thuringiensis, a natural bacterial insecticide.
