Origin
Perityle staurophylla (Barneby) Shinners var. homoflora T.K. Todsen is a member of the Asteraceae family and is native to North America, specifically to the southwestern United States and Mexico.
Common Names
Perityle staurophylla var. homoflora is commonly known as crossleaf brickellbush or simply brickellbush.
Uses
Perityle staurophylla var. homoflora is not commonly used for medicinal or culinary purposes, but it plays an important role in the ecosystem as a food source for various insects and animals, as well as providing habitat and shelter.
General Appearance
Perityle staurophylla var. homoflora is a perennial shrub that typically grows up to 3-4 feet tall and wide. It has multiple stems that are densely covered in small, silver-gray leaves that are arranged in an alternating pattern. The leaves are generally oblong or lanceolate and can measure up to 1 inch in length. The plant produces small, yellow flowers that are arranged in clusters, which bloom from late spring to early summer. The flowers attract various pollinators, including bees and butterflies. The plant's fruit is a seed that is enclosed in a small, hairy achene.
Light Requirements
Perityle staurophylla var. homoflora is a plant that thrives in full sun conditions. It requires at least 6 hours of direct sunlight per day, making it an excellent choice for sun-drenched areas. In areas with scorching temperatures, the plant may benefit from partial shade in the afternoon. Ensuring the plant has adequate light assures good growth and proper flowering.
Temperature Requirements
Perityle staurophylla var. homoflora is a plant that is quite hardy and can tolerate heat and drought reasonably well. The plant prefers a temperature range of 55–85 °F (13–29 °C). The plant is naturally adapted to desert conditions, where shady temperatures are almost non-existent. High humidity levels might be detrimental to the plant's health, making it susceptible to fungal diseases.
Soil Requirements
Perityle staurophylla var. homoflora grows well in well-drained, sandy, or loamy soils. The plant adapts to a range of soil pH values, but it prefers acidic to alkaline soils at a range of 6.0 to 8.5. As a desert plant, Perityle staurophylla requires minimal water, which necessitates well-draining soil.
Cultivation of Perityle staurophylla var. homoflora
Perityle staurophylla var. homoflora can tolerate a wide range of soil types as long as they are well-draining. It prefers soil that is sandy or rocky, and has a pH between 6 and 7.5. It thrives in areas with a lot of sunlight, so it is recommended to plant it in a sunny spot in the garden.
Watering Needs
Watering needs for Perityle staurophylla var. homoflora depend on the stage of growth and weather conditions. During the growing season, it is recommended to water it regularly to keep the soil moist, but not waterlogged. When it is established, it may do well with less water. It is important to avoid over-watering as this can cause root rot.
Fertilization
Perityle staurophylla var. homoflora does not require frequent fertilization. However, it can benefit from an annual application of a slow-release fertilizer in the spring. Alternatively, organic options such as compost or manure can be used to fertilize the plant. It is best to avoid over-fertilizing as this can lead to leaf burn and other damage.
Pruning
Pruning is not necessary for Perityle staurophylla var. homoflora, but it can be beneficial. Regular pruning can help to maintain the plant's shape and prevent it from becoming too leggy. It is recommended to prune in the early spring before new growth begins. Use sterile pruning tools to avoid spreading any diseases.
Propagation of Perityle staurophylla (Barneby) Shinners var. homoflora T.K. Todsen
Perityle staurophylla (Barneby) Shinners var. homoflora T.K. Todsen, also known as Navajo Rock Daisy, can be propagated through both seed and vegetative methods.
Seed Propagation
The easiest way to propagate Navajo Rock Daisy is through seeds. The seeds can be collected from mature plants in the fall once the flowers have faded. The seeds should be kept in a dry, cool place until the spring when they can be sown indoors or directly in the garden. Soil should be well-draining and mixed with sand to allow for better seedling emergence.
Seeds can be sown directly in the soil and should be covered lightly with soil and kept moist. Germination typically occurs within 1-2 weeks.
Vegetative Propagation
Navajo Rock Daisy can also be propagated through vegetative methods such as stem cuttings or division. Stem cuttings should be taken in the late summer or early fall from young, healthy plants. The cuttings should be 4-6 inches long and taken from the non-flowering stem.
The cuttings should be dipped in rooting hormone and planted in well-draining soil mixed with sand. They should be kept moist and in indirect light until roots have formed and new growth is evident. Division can also be done in the spring or fall when the plant has become established.
With proper care and attention, Navajo Rock Daisy can be easily propagated through seed or vegetative methods and will add beauty to any garden or landscape.
Disease Management
Perityle staurophylla var. homoflora typically grows in arid regions where disease incidence is generally low. However, the following diseases may affect the plant:
- Root rot: This soil-borne disease typically affects plants growing in poorly drained soil. It can cause wilting, stunted growth, and eventually death. To manage root rot, ensure proper soil drainage and avoid overwatering the plant.
- Fungal leaf spots: These are caused by various fungal pathogens and can cause small, circular spots on leaves. Fungal leaf spots can cause defoliation and weaken the plant. To manage fungal leaf spots, prune affected leaves and ensure adequate air circulation around the plant.
Pest Management
Perityle staurophylla var. homoflora is generally not heavily targeted by pests. However, the following pests may infest the plant:
- Spider mites: These are small, sap-sucking pests that can cause yellowing and browning of leaves and premature leaf drop. To manage spider mites, regularly spray the plant with water to increase humidity and avoid over-fertilization that can promote mite infestation.
- Whiteflies: These are small, sap-sucking insects that can cause yellowing of leaves, stunted growth, and defoliation. To manage whiteflies, use insecticidal soap or neem oil and ensure adequate air circulation around the plant.
