DETAILS

Care Instructions
Verbascum blattaria is relatively easy to care for. It prefers full sun and moderate temperatures. The plant is drought-tolerant and does not require frequent watering. It thrives in well-drained soil and can tolerate a range of soil types. Humidity levels should be moderate, and the plant does not require high humidity to thrive.
Soil
Verbascum blattaria prefers well-drained loamy soil but can tolerate sandy or clay soils. The soil should be allowed to dry out between waterings to prevent root rot. Good drainage is essential for the plant's health.
Fertilizer
This plant does not require regular fertilization. If desired, a balanced, slow-release fertilizer can be applied in the spring to support growth, but it is generally not necessary.
Repotting
Verbascum blattaria can be repotted if grown in containers, although it is more commonly grown outdoors. Repotting should be done in the spring when the plant is still in its rosette stage. Use a well-draining potting mix and ensure the new container has adequate drainage holes.
Propagation
Propagation of Verbascum blattaria is typically done by seed. Seeds can be sown directly in the garden in the fall or early spring. They require light to germinate, so they should be sown on the soil surface and not covered. Germination usually occurs within 2-3 weeks.
Pruning
Pruning is not generally required for Verbascum blattaria. However, deadheading spent flowers can encourage more blooms and prevent self-seeding if that is not desired. Cut back the flower stalks after blooming to maintain a tidy appearance.
Toxicity
Verbascum blattaria is not known to be toxic to pets or humans. All parts of the plant are considered safe, making it a good choice for gardens where pets and children are present.
