Overview
Malacothrix saxatilis (Nutt.) Torr. & Gray var. implicata (Eastw.) Hall is a flowering plant commonly known as the desert dandelion. It is native to the southwestern United States, including states like California, Nevada, Arizona, and New Mexico. This plant is a part of the Asteraceae family, and it usually grows in arid and sandy habitats such as desert slopes, valleys, and plains.
Description
The desert dandelion is a low-growing perennial herb that generally stands between 2 to 16 inches tall. Its branched stem is covered with glandular hairs, which often gives it a sticky feel. The leaves are mostly basal, meaning they arise at the base of the plant, and are deeply toothed or lobed. The plant bears a single yellow flower head, which appears as a daisy-like bloom. The flower head grows up to 2 inches in diameter and is held above the foliage. The plant blooms from February to May and occasionally produces a second flowering in the fall.
Uses
Malacothrix saxatilis (Nutt.) Torr. & Gray var. implicata (Eastw.) Hall is a popular ornamental plant that is often used for its attractive flowers. It is also used for medicinal purposes and is believed to have healing properties for a variety of ailments. Some Native American tribes used the plant as a food source, either as a cooked vegetable or in salad. In addition, it is used in landscaping to stabilize sand dunes and rehabilitate disturbed soils.
Light Requirements
Malacothrix saxatilis (Nutt.) Torr. & Gray var. implicata (Eastw.) Hall thrives in full sunlight and prefers to be in an area where it can receive at least six hours of direct sunlight a day. It is not adapted to grow in shade or low light conditions and may struggle to survive, let alone flourish, if not exposed to enough sunlight.
Temperature Requirements
The ideal temperature range for Malacothrix saxatilis (Nutt.) Torr. & Gray var. implicata (Eastw.) Hall is between 18°C to 30°C. This plant can tolerate cold to some extent but is not frost-resistant and may die if left in areas with too much frost. High temperatures are not a major issue for the plant, but if temperatures get too high, the plant may wilt due to excessive transpiration.
Soil Requirements
Malacothrix saxatilis (Nutt.) Torr. & Gray var. implicata (Eastw.) Hall is commonly found growing in rocky soil. It prefers soil that is well-drained, nutrient-poor, and sandy or gravelly. This plant can also survive on poor soil or soil with low fertility due to its ability to store water in its leaves and roots. The pH level of the soil should be relatively balanced, ranging from slightly acidic to slightly alkaline with a pH range of 6.0 to 7.5.
Cultivation Methods
Malacothrix saxatilis var. implicata grows well in full sun or part shade and can tolerate various soil types, including sandy, loamy, and clay soils. However, it prefers well-drained soil with a neutral pH level. When planting, make sure to space the plants about 12-18 inches apart to allow enough room for growth.
Watering Needs
The plant does not require watering frequently, as it can handle dry conditions. Watering is necessary only when the soil is completely dry. Overwatering can lead to root rot, which can be detrimental to the plant's health. It's best to use a drip irrigation system to deliver water directly to the roots, which helps reduce evaporation and ensures that the soil stays moist but not waterlogged.
Fertilization
Malacothrix saxatilis var. implicata does not require frequent fertilization. However, it's beneficial to add organic matter to the soil before planting to provide nutrients and improve soil structure. A balanced, slow-release fertilizer can also be applied once or twice during the growing season to supplement the plant's nutritional needs. Follow the recommended rates of the fertilizer to prevent over-fertilization, which can cause damage to the plant.
Pruning
Pruning is not necessary for Malacothrix saxatilis var. implicata, as it has a natural, compact growth habit. However, if you notice any diseased, damaged, or dead stems or leaves, you can remove them using sterilized pruning shears. It's essential to sanitize the tools between cuts to prevent the spread of diseases. Also, remove any spent flowers to encourage the development of new blooms.
Propagation of Malacothrix Saxatilis
Malacothrix saxatilis (Nutt.) Torr. & Gray var. implicata (Eastw.) Hall is a perennial herbaceous plant that belongs to the family of Asteraceae. Propagation of this plant can be done by various methods.
Propagation by seeds
Propagation of Malacothrix saxatilis can be done by using its seeds. The seed propagation method is recommended as it is easy and gives better results. The seeds should be sown in late spring or early summer when the soil temperature is above 10°C. The seeds are sown at a depth of 3mm and should be spaced about 10cm apart. The soil needs to be kept moist, and germination can take place within 2-3 weeks.
Propagation by cuttings
Propagation of Malacothrix saxatilis can also be done by taking stem cuttings. The cuttings should be taken in late spring or early summer when the plant is actively growing. The cuttings should be about 10cm long and should be taken from the non-flowering stems. The cuttings are then dipped in a rooting hormone and should be planted in a well-drained soil mix. The soil should be kept moist, and the cutting should take root within 3-4 weeks.
Propagation by division
Propagation of Malacothrix saxatilis can also be done by dividing the existing plant. The best time to divide the plant is in early spring before the plant starts producing new shoots. The plant should be carefully dug up and the roots should be gently separated. The divided plants should be replanted in a well-drained soil mix and kept moist. The plant should start growing within a few weeks.
