Common Names
Hinckley's brickellbush is also known by other common names such as Hinckley Brickellbush, Hardenbergia, and Tangle Head.
Uses of Brickellia brachyphylla var. hinckleyi
Brickellia brachyphylla var. hinckleyi is known for its ornamental value due to its beautiful and colorful flowers. However, there are no known medicinal, edible, or other practical uses for this plant.
General Appearance of Brickellia brachyphylla var. hinckleyi
Hinckley's brickellbush grows up to 1-3 feet tall with a spread of 2-3 feet. The plant has a shrubby and branching growth habit with narrow leaves that are light green in color and covered with fine hairs. In late summer to fall, the plant produces showy clusters of purple-pink, daisy-like flowers that attract bees, butterflies, and other pollinators. The plant prefers sandy and well-drained soils and can thrive in full sun to partial shade.
Light Requirements
Brickellia brachyphylla var. hinckleyi typically grows in areas with abundant sunlight. It can tolerate partial shade, but it performs best when exposed to full sunlight for at least 6 hours a day. Therefore, it is recommended to plant Brickellia brachyphylla var. hinckleyi in areas that receive direct sunlight.
Temperature Requirements
Brickellia brachyphylla var. hinckleyi is adapted to warm climates and can withstand high temperatures ranging from 65 to 85°F. It grows best in USDA zones 7-10, where the average temperature ranges between 50 to 70°F. The plant can tolerate occasional freezes, but prolonged periods of frost can damage the leaves and stems.
Soil Requirements
Brickellia brachyphylla var. hinckleyi prefers well-draining soils that are moist and rich in organic matter. The plant can tolerate a wide range of soil types, including loam, sandy, or clay soils. However, it is essential to ensure that the soil has good drainage to prevent waterlogging. The ideal pH range for Brickellia brachyphylla var. hinckleyi is between 6.0 and 7.5. Additionally, adding compost or organic fertilizers can improve soil quality and provide nutrients that the plant needs for healthy growth.
Cultivation Methods
Brickellia brachyphylla (Gray) Gray var. hinckleyi (Standl.) Flyr is an excellent plant to cultivate in a garden bed or in a container. The plant grows best in full sun to partial shade and prefers well-draining and alkaline soil.
It is important to choose a location that is protected from strong winds that may damage the delicate stems of the plant. Planting the Brickellia in the fall season is advisable, as it allows the roots to establish before the onset of winters.
Watering Needs
Brickellia brachyphylla (Gray) Gray var. hinckleyi (Standl.) Flyr requires moderate watering. Overwatering can result in root rot and wilting, while underwatering may lead to stunted growth and a withering of the leaves.
It is ideal to water the plant early in the morning or in the evening to prevent moisture loss from the heat of the day. The best way to determine whether the plant requires watering is by checking the moisture level of the soil. If the top 1-2 inches of soil feel dry to the touch, water the plant.
Fertilization
Brickellia brachyphylla (Gray) Gray var. hinckleyi (Standl.) Flyr does not require frequent fertilization. A single application of a balanced fertilizer in the early spring, just before new growth starts, is usually sufficient for the entire growing season.
It is advisable to follow the instructions on the fertilizer package and avoid over-fertilizing, as it may lead to weak stems and leaves that are susceptible to pests and diseases.
Pruning
Pruning Brickellia brachyphylla (Gray) Gray var. hinckleyi (Standl.) Flyr is beneficial for maintaining the plant's shape and promoting bushy growth. The ideal time for pruning the plant is just before the onset of spring when new growth begins.
Deadheading the flowers and removing any damaged or diseased branches will enhance the plant's appearance and prevent the spread of pests and diseases. It is also recommended to cut back the plant's stems by 1/3 after the first flush of flowering to stimulate new growth and encourage more blooms.
Propagation of Brickellia brachyphylla var. hinckleyi
Brickellia brachyphylla var. hinckleyi is a beautiful flowering plant that can be propagated through various methods:
Seed Propagation
One of the most common methods of propagation for Brickellia brachyphylla var. hinckleyi is through seed propagation. The plant produces small seeds that can be collected from the matured seed heads. Once collected, the seeds should be cleaned and sown into the germination tray or pots filled with a well-draining potting mix. The potting mix should be kept moist but not waterlogged, and the tray should be placed in a warm, bright location, out of direct sunlight. The seeds should germinate within a few weeks and can be transplanted once they have developed their second set of leaves.
Division
Another method of propagation for Brickellia brachyphylla var. hinckleyi is through division. This method is best done in early spring before new growth begins. The plant should be dug up carefully and gently separated into smaller sections, ensuring that each division has a sufficient number of roots. The divisions can then be planted in their new location, and the soil should be kept moist but not waterlogged until new growth is visible.
Stem Cuttings
Stem cuttings are another way to propagate Brickellia brachyphylla var. hinckleyi. Cuttings should be taken from new growth in the spring or early summer, using sharp, clean shears. Cuttings should be 3-4 inches in length and include at least two nodes. The lower leaves should be removed, and the cuttings should be dipped in rooting hormone. The cuttings should then be planted in a pot filled with a well-draining potting mix, ensuring that the lower node is buried in the soil. The pots should be kept moist and in a bright but indirect light until new growth appears.
Disease Management
Brickellia brachyphylla var. hinckleyi is generally considered to be a hardy species that is relatively disease-resistant. However, there are a few diseases that can affect this plant.
A common disease that can affect this plant is powdery mildew, which appears as white or gray powdery spots on the leaves and flowers. To manage powdery mildew, remove affected plant parts and dispose of them away from the plant. Additionally, provide good air circulation around the plant and avoid overhead watering. Fungicidal sprays can also be used to manage powdery mildew.
Another disease that can affect Brickellia brachyphylla var. hinckleyi is leaf spot, which appears as small, circular spots on the leaves. To manage leaf spot, remove affected plant parts and dispose of them away from the plant. Avoid overhead watering and keep the area around the plant free of debris to prevent the disease from spreading. Fungicidal sprays can also be used to manage leaf spot.
Pest Management
Like many plants, Brickellia brachyphylla var. hinckleyi is susceptible to a few pests, including spider mites and aphids.
Spider mites are tiny pests that suck the sap from the leaves of the plant, causing yellowing and wilting. To manage spider mites, wash the plant with a strong stream of water to dislodge the pests. Additionally, keep the plant well-watered and provide good air circulation to prevent infestation. In severe cases, insecticidal sprays may be necessary to manage spider mites.
Aphids are small, soft-bodied insects that also suck sap from the leaves of the plant. They can be recognized by their pear-shaped bodies and long antennae. To manage aphids, wash the plant with a strong stream of water to dislodge the pests. Alternatively, use insecticidal sprays to manage infestations. Ladybugs and lacewings are natural predators of aphids and can be attracted to the garden to help manage the pest.
