Cultivation methods
Thelypodium rollinsii Al-Shehbaz, commonly known as Rollins' thelypodium, is a herbaceous perennial plant that belongs to the Brassicaceae family. It is native to North America and grows in semi-desert habitats, rocky slopes, open woodlands, and prairies. To cultivate this plant, you should start by obtaining seeds from a reputable supplier.
Prepare a planting bed in a sunny or partially-shaded place with well-draining soil. Loosen the soil with a garden fork or tiller, then sow the seeds in rows about 2 inches apart. Cover the seeds lightly with soil, then water the bed gently. Keep the soil moist until the seedlings emerge, then thin them to a spacing of about 8 inches apart.

Fertilization
While Thelypodium rollinsii Al-Shehbaz doesn't require much fertilizer, adding organic matter to the soil can promote growth and flowering. Work compost or aged manure into the topsoil at the start of the growing season. You can also use a balanced fertilizer once or twice during the growing season, following the manufacturer's instructions. Avoid over-fertilizing, as this can cause the plant to produce excessive foliage at the expense of flowers.
Pruning
Minimal pruning is required for Thelypodium rollinsii Al-Shehbaz. Deadhead spent flower stems to encourage more blooms.

Propagation of Thelypodium rollinsii Al-Shehbaz
Thelypodium rollinsii Al-Shehbaz, commonly known as Rollins' mustard, is a perennial plant species that belongs to the family Brassicaceae. The propagation of Thelypodium rollinsii can be done either through seeds or stem cuttings.
Propagation through seeds
The propagation through seeds is the easier and more common method of propagating T. rollinsii. The seeds can be collected from the matured pods during late summer or early fall, after the flowering season. Once the seeds are collected, they can be stored in a cool, dry place in a sealed container until the next spring.
Before planting the seeds, it is recommended to soak them in water for several hours to weaken the hard seed coat. After soaking, the seeds can be sown in trays or pots using well-draining sterile soil. The seeds should be covered lightly with soil and kept moist. The trays or pots should be placed in a warm and sunny area until germination, which can take up to three weeks.
Propagation through stem cuttings
The propagation through stem cuttings can be done during late spring or summer. Select a healthy stem from the parent plant and cut a 3-5 inches portion at a 45-degree angle using clean and sharp garden shears. Remove the lower leaves and flowers, leaving only a few leaves on the top.
Apply a rooting hormone to the cut end of the stem and insert it into a well-draining potting mix. Water the soil well and keep it moist by covering it with a plastic bag or a glass jar. Place the cutting in a bright area without direct sunlight and maintain a temperature of 70-75 °F. After a few weeks, new growth should appear, indicating successful rooting. Once sufficient roots have developed, the new plant can be transplanted into a larger container or a well-draining garden bed.
Overall, Thelypodium rollinsii Al-Shehbaz is an easy-to-grow plant that can be propagated through both seeds and stem cuttings, providing many opportunities to expand your garden with this beautiful perennial plant species.
Disease and Pest Management for Thelypodium rollinsii Al-Shehbaz
Thelypodium rollinsii Al-Shehbaz is generally healthy and resistant to most diseases and pests. However, like any other plant, it may get affected by some diseases and pests. Here are the most common diseases and pests that might affect Thelypodium rollinsii Al-Shehbaz and suggestions on how to manage them:
Diseases:
1. Cabbage Whitefly: Cabbage whiteflies are tiny, white, moth-like insects that suck the sap from the underside of leaves, causing yellowing and stunting of the plant. The infested leaves may also become sticky due to the honeydew secreted by the whiteflies. To manage them, spray the plant with a stream of water to remove the whiteflies from the leaves. You can also introduce predatory insects like ladybugs and lacewings to control the population of whiteflies.
2. Aphids: Aphids are tiny, pear-shaped insects that feed on the sap of the plant, causing it to wilt and die. They also secrete a sticky substance called honeydew that attracts ants and other insects. To manage them, spray the plant with a solution of water and mild soap or neem oil. You can also introduce predatory insects like ladybugs and lacewings to control the population of aphids.
Pests:
1. Rhizoctonia: Rhizoctonia is a fungus that causes root rot, stem rot, and leaf spot. The plant may wilt and turn yellow, and the leaves may have dark brown spots. To manage it, avoid overwatering and ensure proper drainage. Remove the infected plant parts and dispose of them properly. You can also apply a fungicide to the soil to control the fungal growth.
2. Clubroot: Clubroot is a soil-borne disease that causes the roots to become thick, distorted, and swollen. The plant may wilt, and the leaves may turn yellow. To manage it, avoid planting in contaminated soil. Rotate the crops and plant a non-cruciferous plant in the infected soil. You can also apply a fungicide to the soil to control the disease.
Implementing proper disease and pest management practices can help keep your Thelypodium rollinsii Al-Shehbaz healthy and thriving. Regularly inspect and monitor your plants for any signs of infections and infestations, and take prompt actions to manage them.
