Clustered Broomrape

Aphyllon fasciculatum

Clustered Broomrape (Aphyllon fasciculatum) is a parasitic plant species native to the Western United States. It typically grows on the roots of desert shrubs, and can also be found parasitizing other plants such as alfalfa and milkweed. It is a yellow, flowering plant with many pointed stems, which branch off into clusters. It has no true leaves or roots, and absorbs nutrients from the host plant, making it a true parasite. Clustered Broomrape blooms in summer and is drought-tolerant, making it an excellent choice for dry climates.

watering

Clustered Broomrape generally requires less frequent watering as too much water can cause root rot and other problems. When watering, the soil should be allowed to dry out between waterings. For best results, water only when the top 2 to 3 inches of soil have dried out. During the summer months, it's recommended to water the plant once or twice a week. During the winter, the plant will need less water and should be watered only when the soil is completely dry. If the area experiences extreme temperatures or dryness, more frequent watering may be needed to ensure the plant receives enough water. It's important to keep an eye on the soil to make sure it is not drying out at a faster rate than expected.

sunlight

Clustered Broomrape (Aphyllon fasciculatum) prefers a location in full sun as it needs 6-8 hours of direct sunlight each day to stay healthy and promote flowering. The sunlight should be evenly distributed throughout the day, so it is best to locate the plant in a spot with as little shade as possible. The plant also requires regular watering, so access to a water source like a hose or a sprinkler system is beneficial. Avoid placing the plant in a spot where it might suffer from heat stress, such as in areas that have intense afternoon sun.

pruning

Clustered broomrape should be pruned in late winter or early spring, before new growth begins. To prune, remove any old or dead stems and leaves, and selectively remove new growth that is unproductive or thickening the center of the plant. Allow the plant to remain woody and open, avoiding over-pruning, as this can weaken the plant. Additionally, prune flowering stems no longer than half their original length. Prune 1 or more times per year to encourage air circulation, reduce crowding, and allow for additional flowering.
