Common Names
Elymus elymoides (Raf.) Swezey ssp. californicus (J.G. Sm.) Barkworth, comb. nov. ined. is commonly known as squirreltail, bottlebrush, and giant wildrye.
Uses
The plant is often used for erosion control and as a forage plant for livestock. Native Americans also used the plant for medicinal purposes, such as treating rheumatism and coughs.
General Appearance
Elymus elymoides (Raf.) Swezey ssp. californicus (J.G. Sm.) Barkworth, comb. nov. ined. is a perennial grass that can reach up to 6 feet tall. It has long, narrow leaves that grow from the base of the plant and a dense, cylindrical seed head that resembles a bottle brush. The seed head is typically tan or golden in color and can be up to 10 inches long. The plant's roots are long and fibrous, allowing it to withstand drought conditions.
Typical Growth Conditions for Elymus elymoides ssp. californicus
Elymus elymoides ssp. californicus is a cool-season perennial grass that is commonly found in California, Nevada, and Oregon. This grass species typically grows in open, sunny areas, along roadsides, hillsides, and slopes. Its growth conditions include:
Light
Elymus elymoides ssp. californicus thrives in full sun, which means it requires at least 6 hours of direct sunlight daily. Its photosynthetic rate increases under full sunlight, which leads to better growth and development. However, it can also tolerate partial shade, but its growth rate may reduce in such conditions.
Temperature
The typical temperature range for Elymus elymoides ssp. californicus growth is between 5°C and 25°C (41°F to 77°F). However, this grass species prefers cooler temperatures of around 15°C to 20°C (59°F to 68°F). It has a low tolerance for high temperatures, especially during the summer months, which can cause leaf senescence and slow growth or even death.
Soil Requirements
Elymus elymoides ssp. californicus prefers well-drained soils that are rich in organic matter. It can grow on a wide range of soil types, including loamy, sandy, and clay soils. However, it does not tolerate waterlogged or poorly-drained soils, which can cause root rot or other diseases. This plant species can also grow in soils with a pH ranging from 5.5 to 7.5.
In summary, Elymus elymoides ssp. californicus requires full sunlight, cooler temperatures, and well-drained soils with sufficient organic matter to thrive. Understanding these growth conditions is essential when growing this perennial grass plant for various ecological, conservation, and agricultural purposes.
Cultivation methods
Elymus elymoides ssp. californicus is a hardy perennial plant that is native to the western United States. It is well adapted to dry, sandy soils and can withstand hot, sunny conditions. The plant prefers full sun and is relatively easy to grow.
When planting, it is important to prepare the soil by clearing away any weeds or debris and loosening the soil. The plant should be watered thoroughly after planting and then only when the soil has dried out between waterings. Over-watering can lead to root rot and other problems.
Watering needs
Elymus elymoides ssp. californicus is a drought-tolerant plant that does not require much water once established. During the first few weeks after planting, the plant will need to be watered more frequently to help it establish its root system. After that, it can be watered sparingly, only when the soil has dried out completely. It is important to avoid over-watering, as this can lead to root rot and other problems.
Fertilization
Elymus elymoides ssp. californicus is a low-maintenance plant that does not require much fertilization. If the soil is particularly poor, a slow-release, balanced fertilizer can be applied in the spring. However, it is important to avoid over-fertilizing, as this can lead to too much foliage growth at the expense of flowers and seeds.
Pruning
Elymus elymoides ssp. californicus does not require much pruning. If the plant becomes unruly or starts to spread out of control, it can be cut back after flowering to prevent it from becoming too leggy. However, it is important to avoid cutting back the plant too severely, as this can harm the plant and reduce its ability to flower and produce seeds.
Propagation of Elymus elymoides ssp. californicus
Elymus elymoides ssp. californicus can be propagated through both sexual and asexual methods:
Sexual propagation
Seeds of Elymus elymoides ssp. californicus can be collected in the late summer or early fall, when the seed heads have turned beige or brown. The seeds should be stored in a cool, dry place until planting. In the spring, the seeds can be sowed directly in the ground, approximately ¼ inch deep, in an area with good soil drainage and full sun exposure. Germination will occur in 7-21 days, depending on soil temperature. Alternatively, seeds can be started indoors 4-6 weeks before the last frost date and transplanted outdoors once the seedlings have grown to a size of about 6 inches.
Asexual propagation
Elymus elymoides ssp. californicus can also be propagated through vegetative means, such as division or rhizome cuttings. Division should be done in the early spring before the plant begins active growth. The clump of grass should be dug up and separated into sections, making sure each section has enough roots and shoots. The sections can be replanted at the same depth as the original clump. Rhizome cuttings can be taken in late summer or early fall when the plant is dormant. The rhizomes should be cut into sections of about 3 inches, and each section should have at least one node. The sections can be planted 2-3 inches deep and spaced about 6-12 inches apart.
Disease Management
Elymus elymoides (Raf.) Swezey ssp. californicus (J.G. Sm.) Barkworth is relatively disease-resistant, but it can still be affected by a few diseases. One of the most common diseases that this plant can face is leaf rust. This fungal disease usually appears during the end of spring or the beginning of summer, and it can cause yellow-orange spots on the leaves. To manage leaf rust, it is recommended to prune the affected leaves and apply a fungicide.
Elymus elymoides (Raf.) Swezey ssp. californicus (J.G. Sm.) Barkworth can also be affected by stripe rust, another fungal disease that causes yellow stripes on the leaves. This disease can be managed by applying a fungicide and making sure the soil is free of debris and dead leaves.
Pest Management
Elymus elymoides (Raf.) Swezey ssp. californicus (J.G. Sm.) Barkworth is also relatively pest-resistant, but it can still be affected by a few pests. One of the most common pests that this plant can face is aphids. These small insects can cause damage by sucking on the sap of the plant, which can weaken it over time. To manage aphids, it is recommended to apply insecticidal soap or neem oil to the leaves.
Another pest that can affect Elymus elymoides (Raf.) Swezey ssp. californicus (J.G. Sm.) Barkworth is spider mites. These tiny mites can cause yellow spots on the leaves and can sometimes be mistaken for dust. To manage spider mites, it is recommended to spray the leaves with water to wash them off, or to apply a miticide.
Overall, the best way to manage pests and diseases in Elymus elymoides (Raf.) Swezey ssp. californicus (J.G. Sm.) Barkworth is to maintain a healthy environment for the plant. This includes ensuring that the plant receives adequate water and nutrients, and that the soil is free of debris and dead leaves.
