Description
Alectra is a genus of parasitic flowering plants that belong to the Orobanchaceae family. They are commonly known as the witchweeds and are widely distributed in tropical and subtropical regions around the world. These plants grow by attaching themselves to the roots of other plants and extracting nutrients from them. The Alectra species have no chlorophyll and thus rely fully on their host plants for survival. They are considered harmful to crops and are responsible for causing significant damage to agricultural yields.

Fertilization: Alectra plants do not require any fertilization as they do not have chlorophyll and cannot produce their food.
Soil: Alectra plants grow on the roots of other plants and thus do not require any soil to grow.
Sunlight: Alectra plants require partial shade to full sun exposure.
Hardiness Zones: Alectra plants are hardy in USDA zones 9-11.
Common Pests & Diseases
Alectra plants are not commonly affected by pests and diseases. However, they are known to be hosts for several plant viruses that can affect the health of the host plant.
Habitat
Alectra plants are widely distributed in tropical and subtropical regions around the world. They grow on the roots of other plants and can be found in various habitats such as forests, grasslands, and agricultural fields.
