Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz typically grows in full sun to partial shade in its native range. It requires bright and indirect sunlight for optimal growth and flowering. If grown indoors, it should be placed near a south-facing window or under grow lights that provide full spectrum light.
Temperature Requirements
This plant is adapted to the climatic conditions of Oklahoma. It can tolerate a wide range of temperatures, as long as it is not exposed to extreme heat or extreme cold. It can survive temperatures as low as -15° F (-26° C) and as high as 110° F (43° C). The ideal temperature range for Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz is between 60-85° F (16-29° C).
Soil Requirements
Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz prefers fertile, well-draining soil that is rich in organic matter. The ideal soil pH range for this plant is between 6.5 and 7.5. It can tolerate some alkalinity, but does not grow well in highly acidic soil. It can also tolerate some drought, but the soil should not be allowed to completely dry out. During the growing season, the plant should be watered deeply and allowed to dry out partially before the next watering.
Cultivation Methods
Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz is best grown in well-drained soil with a neutral to slightly alkaline pH. This plant grows best in full sun and can thrive in hot and dry climates. It can be grown from seed or propagated through stem cuttings. To grow from seed, the seeds should be sown directly in the soil in the early spring. When propagating through stem cuttings, the cuttings should be taken from the plant’s new growth, placed in a potting mix and kept moist until roots develop.
Watering Needs
Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz prefers a drier soil and can tolerate drought conditions better than overwatering. Water thoroughly only when the soil is completely dry to the touch. During the first year, Water it more frequently to establish a strong root system. Once established, watering can be less frequent.
Fertilization
Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz does not require heavy fertilization and can be grown with minimal fertilization. If you desire to fertilize, depending on the soil condition, a slow-release fertilizer with a NPK balance of 10-10-10 can be used. To avoid overpowering the plant with nutrients, only apply minimal fertilizer, once a year during early spring.
Pruning
Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz does not require heavy pruning. To keep a clean appearance, it can be lightly pruned in late winter or early spring before the growing season. Remove the overgrown or damaged branches, pruning to promote new growth. If the plant has blossomed, for aesthetics cut off the spent flowers thus redirecting the plant's energy to the development of sturdier growth.
Propagation of Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz
Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz, also known as Oklahoma thelypody, is a perennial plant that belongs to the Brassicaceae family. The plant is usually propagated from seeds, which can be obtained from ripe pods.
Seed collection
Seeds of Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz can be collected from the plant when the pods turn brown and start to split open. Care should be taken not to damage the pods during seed collection, as this could result in reduced seed viability. The seeds should be stored in a cool, dry place until they are ready for use.
Seed preparation
Before planting, the seeds of Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz should be scarified to improve their germination rate. Scarification can be done by gently rubbing the seeds with sandpaper or by soaking them in a solution of sulfuric acid for a few minutes. The seeds should then be rinsed thoroughly with water.
Seed planting
The seeds of Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz should be planted in a well-draining soil mixture that contains equal parts of sand, peat moss, and vermiculite. The seeds should be planted about 1/8 inch deep and watered lightly. The soil should be kept moist but not waterlogged until the seeds germinate.
Care of seedlings
Once the seedlings emerge, they should be kept in a bright location but protected from direct sunlight. The soil should be kept moist but not waterlogged. When the seedlings reach a height of about 2 inches, they can be transplanted into larger containers or planted directly into the ground. If transplanting, care should be taken not to damage the roots.
Disease and Pest Management for Thelypodium wrightii Gray ssp. oklahomense Al-Shehbaz

Common Pests
One of the most common pests that affect Thelypodium wrightii is the flea beetle. These small, jumping insects have the ability to defoliate plants, especially in young or newly established stands. To manage flea beetle infestations, regular monitoring and early intervention is advised. Insecticidal sprays or dusts can be used to control flea beetles, but care should be taken to avoid damage to beneficial insects.
Another pest that can affect Thelypodium wrightii is the diamondback moth. Like flea beetles, diamondback moths can cause significant damage to plants in high numbers. Management strategies for diamondback moths include early detection and application of insecticides as necessary.
Common Diseases
Thelypodium wrightii is prone to fungal diseases such as white rust, which can cause significant damage to the plant. Symptoms of white rust include yellowing or chlorosis of leaves, and the presence of white pustules on the underside of leaves. Management strategies for white rust include cultural practices such as removal of infected plant material and the use of fungicides as needed.
Another fungal disease that can impact Thelypodium wrightii is blackleg, which can cause stem rot and wilting. Management strategies for blackleg include crop rotation and destruction of diseased plant material.
Overall, the key to successful disease and pest management for Thelypodium wrightii is regular monitoring and early detection. By identifying and addressing issues before they become severe, growers can ensure the health and productivity of their plants.
