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

California Broomrape typically requires little to no supplemental watering during its dormant period, which is typically from late Fall to early Spring. During the active growth period, which is typically from late spring to early Fall, it should be watered about once a week, or when its soil is dry 1-2 inches deep. When watering, provide approximately 1-2 gallons of water for each mature plant. It is recommended that watering be done in the morning or late evening.

sunlight

The California Broomrape (Aphyllon californicum subsp. californicum) is a plant species that thrives in sunlight. This plant enjoys full sun to partial shade, with 6 to 8 hours of sunlight per day being ideal. It is important that the California Broomrape is not exposed to any extended periods of direct midday sunlight, as this can result in wilting or scorched foliage. It is best to place the plant in a position where it will receive several hours of direct sunlight in the morning and a few hours in the late afternoon or evening.

pruning

Pruning for California Broomrape should occur in the late spring and early summer after the plant has bloomed. Prune back spent flower stems and thin out areas with excessive growth. Pruning should be done selectively, as there are densely-packed, branched stems which may be sacrificed for a more open, structural look. Avoid cutting stems too short, or too drastically, as the plant may not respond and could be damaged.
