Growth Conditions of Lessingia germanorum Cham. var. tomentosa (Greene) J.T. Howell
Lessingia germanorum Cham. var. tomentosa (Greene) J.T. Howell, commonly known as woollyhead lessingia, is a perennial plant native to coastal regions of California and Baja California. This plant is a member of the Asteraceae family and is valued for its attractive, woolly grey-green foliage and showy clusters of lavender or white flowers that bloom from summer to fall.
Light Conditions
Woollyhead lessingia thrives in full sun to partial shade conditions.

In the coastal areas where it is native, woollyhead lessingia can tolerate temperatures as low as 20°F (-7°C) and up to 100°F (38°C). However, it may struggle in areas with prolonged heat waves or extreme cold temperatures.
Soil Requirements
Woollyhead lessingia prefers well-draining, sandy or loamy soil with a pH range of 6.5-8.0. This plant is adapted to coastal soils that are often nutrient-poor, so it does not need heavy fertilization. However, it may benefit from occasional applications of organic fertilizers or compost to promote healthy growth. Woollyhead lessingia is drought-tolerant once established but benefits from occasional deep watering during prolonged dry periods.

Propagation of Lessingia germanorum Cham. var. tomentosa (Greene) J.T. Howell
The plant Lessingia germanorum Cham. var. tomentosa (Greene) J.T. Howell, commonly known as San Francisco lessingia, can be propagated through various methods including seeds, stem cuttings, and division.
Seed Propagation
This plant can be propagated through seeds which can be collected in late summer or early fall. Once collected, the seeds can be cleaned, dried, and stored in a cool, dry place until it is time to sow them. Sow the seeds in late fall to early winter, or in spring. The seeds should be planted one-eighth inch deep in good quality soil that is moist and well-draining. Keep the soil moist until the seeds germinate, which typically takes several weeks.
Stem Cutting Propagation
Propagation through stem cuttings is another viable method for propagating L. germanorum var. tomentosa. Take cuttings from healthy plants in spring or early summer. Make sure the cutting is about 3-4 inches long, and remove all the leaves from the bottom half of the stem. Dip the cut end in a rooting hormone and place it in a pot filled with moist, sterile rooting soil. Keep the soil moist and place the pot in an area with bright, indirect light. The cutting should develop roots in about 4-6 weeks.
Division Propagation
Propagation through division is usually done in spring or early fall. Dig up the plant and gently separate the roots into smaller sections. Each section should have a portion of the crown and roots. Replant the divisions immediately in well-draining soil, and water them well. Keep the soil moist until new growth appears, and then continue to care for them as you would for mature plants.
Disease management
Lessingia germanorum Cham. var. tomentosa (Greene) J.T. Howell plants may encounter various diseases. Here are some common diseases that could affect the plant:
- Root rot: This disease happens due to excessive moisture. The roots of the plant start to decay and consequently, the plant's growth slows down. To control this disease, ensure proper drainage and avoid overwatering the plant.
- Powdery mildew: A fungus causes powdery mildew. It becomes evident with whitish spots on the leaves. To manage powdery mildew, apply fungicide and prune the infected leaves to prevent spreading.
- Leaf spot: This disease is caused by bacteria that lead to uneven spots on leaves. Remove the infected foliage and apply fungicide to save the plant.
Pest management
Lessingia germanorum Cham. var. tomentosa (Greene) J.T. Howell is prone to attracting pests. Here are some common pests that could affect the plant:
- Spider mites: It attacks the plant's leaves, causing yellowish spots. To manage this pest, rinse the plant with water frequently and apply insecticidal soap.
- Aphids: Aphids suck the sap from the plant's leaves resulting in stunted growth. Control them by applying insecticidal soap and regularly pruning the affected foliage.
- Thrips: This pest causes deformities in the flowers of the plant. Spray insecticide and remove the affected leaves to control thrips' growth in the plant.
