Growth Conditions of Erysimum angustatum Greene non Rydb.
Erysimum angustatum Greene non Rydb., also known as the Inyo Erysimum, is a perennial plant endemic to the western United States. This plant typically grows in rocky or gravelly soils, often in alpine or subalpine environments. Here are some specific growth conditions that are necessary for the optimal growth of this plant:
Light Requirements
Erysimum angustatum prefers full sun exposure for at least six hours a day. The plant may tolerate some shade in the afternoon but grows best in a sunny spot. The plant does not do well under conditions of complete shade and tends to become leggy if not given enough direct sunlight.
Temperature Requirements
The plant can grow in a wide range of temperatures but prefers cooler regions. Erysimum angustatum grows well in temperatures around 50 to 70 degrees Fahrenheit. It can also withstand frost and winter snow. The plant may not tolerate extremely high temperatures and may become susceptible to disease under such conditions.
Soil Requirements
The Inyo Erysimum prefers well-drained soils with a neutral pH level. It can grow in slightly acidic to alkaline soils as well. The plant does well in gravelly soils and in areas where other plants would struggle to thrive. The soil should not be too rich in organic matter as it can lead to the development of soft, weak growth that is susceptible to disease and pests.
Overall, Erysimum angustatum Greene non Rydb. is an excellent plant for rock gardens, border plantings, and dry landscapes, provided the growth conditions are optimal.
Cultivation Methods for Erysimum Angustatum Greene non Rydb.
Erysimum angustatum Greene non Rydb. is a hardy perennial plant that can grow up to 24 inches tall. It is a drought-tolerant plant that prefers well-drained soil with a pH of 6.5 to 7.5. It requires a sunny location that receives at least six hours of sunlight every day.
The plant can be propagated from cuttings or seeds. For cuttings, take 3-4 inch stem cuttings of new growth, remove the lower leaves, dip the cut end in rooting hormone, and plant in well-drained soil. Keep the soil moist, and the cuttings should root in 3-4 weeks.
For seeds, plant them in well-drained soil in the spring or fall. Lightly cover the seeds with soil and keep the soil moist until germination occurs in about 3-4 weeks.
Watering Needs for Erysimum Angustatum Greene non Rydb.
Erysimum angustatum Greene non Rydb. is drought-tolerant and requires minimal watering. Once established, it can go for weeks without water, making it a low-maintenance plant. However, during hot and dry spells, it may require watering once a week to keep the soil slightly moist.
When watering, water the plant deeply to encourage deep root growth and avoid wetting the foliage, which can lead to fungal and bacterial diseases.
Fertilization of Erysimum Angustatum Greene non Rydb.
Erysimum angustatum Greene non Rydb. requires minimal fertilization. In fact, too much fertilizer can lead to leggy growth and fewer flowers. A yearly application of compost or well-rotted manure in the spring is sufficient.
If the soil is lacking in nutrients, an application of a balanced fertilizer with an NPK ratio of 10-10-10 can be applied in the spring. However, it is best to have the soil tested first to determine if fertilizer is needed and in what quantity.
Pruning of Erysimum Angustatum Greene non Rydb.
Erysimum angustatum Greene non Rydb. requires minimal pruning. Deadhead spent flowers to encourage continuous blooming and remove any dead or diseased stems as they appear. In the fall, cut the plant back to 6 inches above the ground to encourage new growth in the spring.
If the plant becomes too leggy or overgrown, cut it back by one-third in the spring before new growth appears. This will encourage bushier growth and more flowers.
Propagation of Erysimum angustatum Greene non Rydb.
Erysimum angustatum Greene non Rydb. commonly known as the Utah wallflower is a popular perennial plant native to western North America. This plant produces beautiful yellow flowers that are attractive to pollinators like bees and butterflies.
For those interested in propagating this plant, there are several viable options available.
Seed propagation
The most common method of propagating Erysimum angustatum is through seed propagation. Seeds can be harvested from mature plants once the seedpods have turned brown and dried out. These seeds can be sown directly into the soil in the fall or early spring. Typically, seedlings will emerge in a few weeks.
Cuttings
Erysimum angustatum can also be propagated through cuttings. The best time to take cuttings is in the late spring or early summer when the plant is in its active growth phase. Cuttings should be taken from the lower part of the plant and inserted into a potting mix that is kept moist. Make sure to remove the lower leaves before inserting the cuttings to ensure proper root growth.
Division
Another method of propagating Erysimum angustatum is through division. This method involves digging up the plant and separating the root ball into smaller sections that can be replanted. This is best done in the early fall or late spring.
By using one or more of these propagation methods, gardeners can produce new plants for their own gardens or to share with others.
Disease and Pest Management for Erysimum Angustatum Greene non Rydb.

Like most plants, the Utah wallflower is susceptible to a range of diseases and pests, which can negatively impact its growth and health. Here are some common diseases and pests that might affect the plant and ways to manage them:
Diseases
Black Rot – Black rot is a fungal disease that affects the leaves and stems of Erysimum angustatum. The symptoms of the disease include dark spots on leaves, leaf drop, and stem lesions. To manage the disease, it is important to remove and destroy infected plant material immediately. Fungicides can also be effective in preventing the spread of the disease.
Clubroot – Clubroot is a soil-borne disease that affects the roots of Erysimum angustatum. The disease causes stunted growth, root deformation, and wilting. To manage the disease, it is important to sanitize garden tools and equipment regularly and remove infected plants immediately. Crop rotation can also be effective in preventing the disease from recurring.
Pests
Aphids – Aphids are small, soft-bodied insects that feed on the sap of Erysimum angustatum. The insects can cause distorted growth and yellowing of leaves. To manage aphids, it is important to spray the plant with a strong jet of water to dislodge the insects. Insecticidal soaps can also be effective in preventing the insects from returning.
Cabbage Loopers – Cabbage loopers are caterpillars that feed on the leaves of Erysimum angustatum. The caterpillars can cause significant damage to the plant. To manage cabbage loopers, it is important to handpick the caterpillars and destroy them. An application of Bacillus thuringiensis, a natural bacterial insecticide, can also be effective in controlling the caterpillars.
