Growth Conditions for Eryngium aristulatum Jepson var. parishii (Coult. & Rose) Mathias & Constance
Eryngium aristulatum Jepson var. parishii (Coult. & Rose) Mathias & Constance, commonly known as Parish's Eryngo, is a herbaceous perennial plant that belongs to the Apiaceae family. It is native to California and requires specific growth conditions for healthy growth and development. The following are the critical growth conditions for this plant:
Light
Parish's Eryngo requires full sunlight exposure for healthy growth. The plant can tolerate partial shade, but the growth and flowering may not be as robust as those in full sun. Therefore, it is essential to plant the Eryngo in a location that allows full sun exposure.

The typical temperature range for Eryngium aristulatum Jepson var. parishii growth is between 60 and 90°F (15 and 32°C). This plant can withstand hot and dry conditions but prefers moderate temperatures. Parish's Eryngo can tolerate light frost but may become stunted or die back during severe winters.
Soil
The ideal soil for Parish's Eryngo is well-draining, loamy soil that is rich in organic matter. The pH level should be neutral to slightly acidic, with a range of 6.0 to 7.5. The plant prefers soil that is not compacted or waterlogged, as this can lead to root rot. Before planting, it is recommended to amend the soil with compost to improve drainage and nutrients.
In conclusion, for optimal growth and development, Parish's Eryngo requires full sunlight exposure, moderate temperatures, and well-draining, loamy soil that is rich in organic matter. By providing the right growth conditions, one can enjoy the stunning blue-green foliage and showy flowerheads of this beautiful plant.
Cultivation
Eryngium aristulatum Jepson var. parishii (Coult. & Rose) Mathias & Constance, commonly known as Parish's eryngo, is a perennial herbaceous plant that is native to California. It is well suited for cultivation in arid and semi-arid regions where the summers are hot and dry. The plant prefers well-draining soils that are rich in organic matter, but it can also grow in sandy or rocky soils.
The plant can be propagated through seeds or root cuttings. The seeds should be sown in late winter or early spring, while the root cuttings are best taken in autumn. The plant can also be divided when it becomes too large for its pot or planting area.
Parish's eryngo prefers full sun to partial shade and can be grown in containers or in the ground. The plant reaches a height of 2-3 feet and a width of 1-2 feet, so provide ample space when planting in the ground or in a pot.
Watering Needs
Parish's eryngo is a drought-tolerant plant and requires less watering than most plants. It is best to water deeply but infrequently. When grown in containers, the soil should never remain soggy as this can lead to root rot. Allow the soil to dry out completely before watering again.
Fertilization
Parish's eryngo does not require frequent fertilization. An application of a slow-release fertilizer in early spring is sufficient. The plant is sensitive to high levels of nitrogen, so avoid fertilizers that contain high amounts of this nutrient.
Pruning
Deadhead spent blooms regularly to encourage the plant to produce more flowers. The plant should be pruned back to the ground in late autumn or early winter. This will help prepare the plant for the next growing season and prevent the plant from becoming too woody.
Propagation of Eryngium Aristulatum Jepson Var. Parishii
Eryngium aristulatum Jepson var. parishii (Coult. & Rose) Mathias & Constance, commonly known as Parish’s Eryngo, is a stunning, evergreen perennial that grows up to 3 ft tall and 2 ft wide. It is native to California’s southern regions, especially in areas with rocky soils and full sun. If you are planning to add this plant to your garden, here are some propagation methods you can use:
Seed Propagation
Eryngium aristulatum Jepson var. parishii can be propagated from seeds. Collect ripe seeds from the plant during the fall months. Sow the seeds immediately in well-draining soil in a seed tray, and keep the soil moist. Germination should occur in 2 to 3 weeks. Once the plants reach 2 to 3 inches, transplant them to individual pots. The plants should be ready to transplant into the garden after 6 to 8 weeks.
Division
Division is another propagation method that you can use for Eryngium aristulatum Jepson var. parishii. Divide the clumps during the early spring months, and make sure that each division has enough roots and at least one healthy shoot. Transplant the divisions in well-draining soil and water them regularly. Avoid overwatering, as the plant does not tolerate wet feet.
Cuttings
Eryngium aristulatum Jepson var. parishii can also be propagated from cuttings, but this method can be a bit tricky. Take cuttings of young stems during the summer months, and make sure that each cutting has at least two nodes. Dip the cuttings in rooting hormone and insert them in planting trays with well-draining soil. Keep the soil moist and the cuttings in a warm, shaded area. After a few weeks, roots should start to develop, and the cuttings should be ready for transplanting in the garden.
Propagation of Eryngium aristulatum Jepson var. parishii can be done with relative ease using any of the above methods. Once established, the plant does not require much maintenance, making it an excellent choice for any garden.

The symptoms of crown rot include wilting, yellowing of the leaves, and the presence of a foul-smelling liquid. To manage crown rot, remove and destroy any infected plant material and ensure that the soil is well-draining to prevent waterlogging.
Powdery mildew: Powdery mildew is a fungal disease that affects the leaves, stems, and flowers of the plant. The symptoms of powdery mildew include the presence of a white powdery substance on the plant’s surface. To manage powdery mildew, use fungicides that are effective against powdery mildew and improve air circulation around the plant by spacing it correctly.
Anthracnose: Anthracnose is a fungal disease that attacks the stems, leaves, and flowers of the plant and causes brown or black spots on them. The symptoms of anthracnose include wilting of the plant and the presence of dark spots on the leaves, stems, and flowers. To manage anthracnose, remove and destroy any infected plant material and improve air circulation around the plant.
Pests
Spider mites: Spider mites are tiny pests that feed on the sap of the plant, causing discoloration and distortion of the leaves. The symptoms of spider mite infestation include the presence of fine webbing on the plant’s surface. To manage spider mites, use insecticidal soap or neem oil to kill them and improve humidity levels around the plant by misting it with water regularly.
Leafhoppers: Leafhoppers are tiny insects that feed on the sap of the plant, causing damage to the foliage by puncturing it with their mouthparts. The symptoms of leafhopper infestation include the presence of yellow or white stippling on the leaves. To manage leafhoppers, use insecticidal soap or neem oil to kill them and improve air circulation around the plant by spacing it correctly.
Caterpillars: Caterpillars are the larvae of moths and butterflies and can cause severe damage to the plant by feeding on the foliage. The symptoms of caterpillar infestation include the presence of large holes on the leaves and stems. To manage caterpillars, manually remove them from the plant and apply Bacillus thuringiensis, a natural insecticide that specifically targets caterpillars.
