Short Styled Thistle

Cirsium brevistylum

Also Known As - Clustered Thistle
Short Styled Thistle (Cirsium brevistylum) is a perennial flowering plant native to the western United States. The vivid violet blooms of the plant attract a variety of pollinating insects, while its prickly rosette is a deterrent to animals that might want to feed on it. The plant has narrow, deeply divided leaves with a white underside that create a unique pattern. Stems measure up to six inches long and the leaves are arrayed like a cup around the flowers. The flower heads can measure up to 1.5 inches in diameter and have soft spines. Short Styled Thistle can be found in valley grassland, dry meadows and rocky slopes. Plant in well-drained soils in sunny locations for best flowering and enjoy this unique species in your garden.

watering

Short Styled Thistle (Cirsium brevistylum) should be watered once or twice a week depending on the season and temperature. Water the plant deeply, saturating the root zone to a depth of 6-10 inches. Reduce the frequency of watering if the plant begins to show signs of stress such as wilting or yellowing of leaves. During hot and dry weather, water may be necessary more than twice a week. During cooler and wetter weather, watering can be reduced to once a week. Soil should be allowed to dry out slightly between waterings. If the soil is overly wet, you may need to reduce watering frequency to avoid root rot.

sunlight

Short Styled Thistle (Cirsium brevistylum) prefers full sun conditions for best growth. 6 to 8 hours of direct sunlight during the day is ideal, although it can tolerate some partial shade throughout the day. The plant does best in warmer climates with plenty of sun and is moderately drought tolerant. In hotter and more arid climates, it is important to provide supplemental irrigation to keep the plant healthy and robust. For most regions, daytime temperatures should range from 60-80 degrees Fahrenheit with slightly cooler nights.

pruning

Short Styled Thistle should be pruned in early spring when the danger of frost has passed. For best results, the plant should be pruned hard and back to the ground each year. This will help promote healthy, strong growth and discourage spread of the plant. Care should be taken when pruning to avoid destroying the florets, as this can result in a loss of the plant’s aesthetic value. Pruning should focus on removing any dead, damaged, or diseased foliage, as well as any excess growth that could lead to congestion in the plant. By maintaining diligent pruning, the short-styled thistle should remain healthy and beautiful throughout the growing season.
