Appearance
Thesium plants are small in size and typically grow up to 20-30 cm tall. They have slender, branching stems and small, narrow leaves that are usually less than 1 cm in length. These plants produce small, inconspicuous flowers that are either green or white in color. The flowers are usually arranged in tight clusters, and they have no petals. Thesium plants are distinctive due to their parasitic nature, which means they rely on other plants to obtain nutrients.
Care Guide
Thesium plants require minimal care, and they are relatively easy to grow. They prefer well-draining soil and a sunny location. These plants do not require frequent watering, and they can tolerate drought conditions. Fertilization is not necessary for Thesium plants, as they obtain their nutrients from their host plants. Thesium is hardy in USDA hardiness zones 5-9.
Common Pests & Diseases
Thesium plants are not commonly affected by pests or diseases. However, they may be susceptible to root rot if they are overwatered. It is important to ensure that the soil is well-draining and that the plant is not sitting in water for prolonged periods.
Habitat
Thesium plants are found in a variety of habitats, including heathlands, grasslands, and woodlands. They are typically found growing in sandy or rocky soils, and they are often associated with other plant species. Thesium plants are distributed across Europe, Asia, and North America.
