"Dwarf Cassian" grass is a cultivar of the popular ornamental grass known as Miscanthus sinensis. Here's some information about it:

1. Appearance: Dwarf Cassian Miscanthus is a compact, clump-forming grass that typically reaches a height and spread of about 2 to 3 feet. It features narrow, arching leaves with a fine texture. The foliage emerges green in spring and turns golden-yellow in the fall, providing a striking display of color.

2. Flowers: In late summer to early fall, Dwarf Cassian Miscanthus produces feathery plumes that rise above the foliage. The plumes start out with a reddish-bronze hue and gradually lighten to silver as they mature. The plumes persist well into winter, providing visual interest even after the foliage has died back.

3. Sunlight: Dwarf Cassian Miscanthus thrives in full sun but can tolerate partial shade. It generally prefers at least 6 hours of direct sunlight per day to bloom and develop its best foliage colors.

4. Soil: This grass prefers well-draining soil with moderate moisture retention. It can tolerate a wide range of soil types, including loamy, sandy, or clay soils, as long as the drainage is good. Amending the soil with compost or organic matter can help improve soil structure and fertility.

5. Watering: Dwarf Cassian Miscanthus has moderate water needs and prefers consistently moist soil. Water deeply and thoroughly, especially during hot, dry weather, to keep the root zone evenly moist. Once established, it is relatively drought-tolerant and can withstand short periods of dryness.

6. Pruning: Pruning requirements for Dwarf Cassian Miscanthus are minimal. You can trim back the foliage in late winter or early spring before new growth emerges to remove any dead or damaged stems. Additionally, you can cut back the entire plant to the ground in late winter to rejuvenate it and promote fresh growth.

7. Uses: Dwarf Cassian Miscanthus is commonly used as a colorful accent plant in landscape beds, borders, and mixed shrub borders. It works well as a specimen plant, mass planting, or container specimen, providing year-round interest with its vibrant foliage and feathery plumes.

Overall, Dwarf Cassian Miscanthus is a versatile and attractive ornamental grass that adds beauty and texture to garden landscapes. With its compact size, fine-textured foliage, and striking plumes, it's a popular choice for gardeners looking to create a dynamic and visually appealing outdoor space.
