Pericome caudata is a species of flowering plant in the aster family known by the common name mountain tail-leaf. It is native to the southwestern United States as far east as Colorado, Oklahoma, and Texas, as well as northern Mexico, where it grows in rocky habitat, often in hills and mountains, and sometimes in disturbed areas. It is a large, branching, leafy perennial herb or subshrub approaching 2 meters in maximum height. It is glandular, resinous, sparsely hairy, and aromatic. The leaves are somewhat triangular, sometimes with a few large teeth or sharp lobes, the blade measuring up to 12 centimeters long and borne on a petiole. The leaf size and shape is variable across the species' range. The inflorescence is a cluster of many flower heads each under a centimeter wide and filled with golden yellow disc florets. The Navajo used this plant for a variety of medicinal and ceremonial purposes.
Mountain tail-leaf is quite resistant to disease and generally does not develop illnesses. Still, it can be affected by pests and diseases present in its surroundings. When they do occur, these infections tend to be mild. For care, this plant needs moderate maintenance. It should be pruned regularly to keep a pleasing appearance and support healthy growth. Fertilizing can also aid in encouraging flowering. Mountain tail-leaf is appropriate for anyone with outdoor space, such as a garden or patio, and does not demand extensive care experience. It can require more attention when grown indoors.
How to keep Pericome Caudata.
Light
Mountain tail-leaf is a sun-loving perennial herbaceous plant that comes from open habitats and often thrives in meadows and grasslands. It prefers full sun but can also tolerate partial sun.
Temperature
Mountain tail-leaf is fairly adaptable to temperature, tolerating high heat and wide temperature fluctuations. In hot conditions, care should be taken with watering and providing adequate shade to prevent sunburn. Conversely, Mountain tail-leaf has relatively low cold tolerance. While it can handle some cold, excessively low temperatures can cause frost damage.
Fertilizer
Typically one spring fertilization is enough for Mountain tail-leaf, although multiple applications can enhance growth. Apply fertilizer every one to one and a half months. Fertilization improves the leaves' appearance and function, helping maintain uniform color and a healthy texture. It also promotes root development and nutrient uptake for the plant's long-term health.
Pruning
Mountain tail-leaf, known for its distinctive tail-like leaves, should be pruned between early and late spring. Trim dead or overgrown branches to promote new growth, improve air circulation, and reduce the risk of disease. Always use clean tools, and avoid heavy pruning during peak growth periods to prevent stress on the plant.
