Erigeron maguirei Cronq. var. harrisonii Welsh is also known as Harrison's Fleabane, and is a member of the Asteraceae or sunflower family. It is endemic to Utah, a state located in the western part of the United States, where it grows in rocky slopes and outcrops at an elevation of 3,000 to 6,000 feet above sea level.
Common Names
Other common names for Erigeron maguirei Cronq. var. harrisonii Welsh are Harrison's Daisy and Harrison's Fleabane. These names were given in honor of John Harrison, a botanist and professor at Brigham Young University in Utah, who studied the mountain flora of the state and was one of the first to recognize the uniqueness of this plant.
Uses
Erigeron maguirei Cronq. var. harrisonii Welsh has no recorded medicinal or culinary uses, but it is an attractive ornamental plant and is grown by some rock garden enthusiasts. It is also valued for its ecological role as a native plant that supports pollinators such as bees and butterflies.
General Appearance
Erigeron maguirei Cronq. var. harrisonii Welsh is a small perennial herb that grows up to 15 cm tall and 30 cm in diameter. It has narrow leaves that are densely arranged on the stem, forming a rosette. The leaves are smooth and dark green on top, while the underside is covered with short hairs. The plant bears small, white or pinkish-purplish flowers that are about 1 cm in diameter. The flowers have yellow centers and are arranged in clusters at the ends of the stems. The plant blooms from May to June.
Light Requirements
Erigeron maguirei Cronq. var. harrisonii Welsh grows best in bright natural light or partial shade. The plant should receive a minimum of 4-6 hours of daily sunlight to support healthy growth. However, too much direct sunlight can cause leaf scorching, so it is important to provide some shade during the hottest part of the day.
Temperature Requirements
This plant prefers moderate temperatures between 55-75°F (13-24°C), which is typical of its native habitat in the mountains of Utah. It can tolerate some cold but is sensitive to frost and freezing temperatures. The plant may go dormant during the winter months but will resume active growth in the spring.
Soil Requirements
The soil for Erigeron maguirei Cronq. var. harrisonii Welsh should be well-draining and rich in organic matter. This plant can tolerate a range of soil types, including sandy, loamy, or clay soils, as long as it is not compacted. The pH level should be slightly acidic to neutral, ideally between 6.0-7.5.
It is important to keep the soil evenly moist but not waterlogged. Overwatering can lead to root rot, which can be fatal. The plant should be watered deeply once a week, or more frequently in hot and dry weather. Mulching around the base of the plant can help to retain moisture and regulate soil temperature.
Cultivation Methods for Erigeron maguirei Cronq. var. harrisonii Welsh
Erigeron maguirei Cronq. var. harrisonii Welsh, also known as Harrison's Fleabane, is a hardy, low-growing perennial plant that is native to the arid regions of the western United States. It is a popular plant for rock gardens and xeriscaping, as it requires minimal water and maintenance.
When cultivating Erigeron maguirei, it is important to choose a planting location that has well-draining soil and receives full sun to partial shade. The plant can tolerate a wide range of soil types, but it does not do well in extremely wet or poorly drained soils.
Watering Needs
Erigeron maguirei requires regular watering to establish itself in the garden or landscape. After that, it is a drought-tolerant plant that can go for long periods without water. When watering, it is important to avoid getting the leaves wet to reduce the risk of disease.
During periods of drought or extreme heat, it is important to water the plant deeply and infrequently to encourage deep root formation. This will help the plant survive during periods of limited rainfall.
Fertilization
Erigeron maguirei does not require much fertilization to thrive. In fact, applying too much fertilizer can lead to excessive foliage growth and reduced flowering. A balanced, slow-release fertilizer can be applied in the spring before new growth begins. Alternatively, a top dressing of compost can help improve soil quality and provide a small amount of nutrients to the plant.
Pruning
Erigeron maguirei does not require much pruning, but it can benefit from a light pruning after the first flush of bloom in the spring. This can help encourage additional flowering and keep the plant looking neat and tidy. Deadheading spent flowers throughout the growing season can also help promote additional blooms.
In the fall, after the last flush of bloom, Erigeron maguirei can be cut back to the ground to prepare it for the winter dormancy period.
Propagation of Erigeron maguirei Cronq. var. harrisonii Welsh
Erigeron maguirei Cronq. var. harrisonii Welsh, commonly known as Harrison’s fleabane, is a perennial herbaceous plant that is native to North America. It is a popular ornamental plant that can be propagated through several methods including:
Seed Propagation
This method involves planting the seeds of Erigeron maguirei Cronq. var. harrisonii Welsh in a suitable growing medium such as a potting mix or soil.

Cuttings Propagation
Another propagation method for Erigeron maguirei Cronq. var. harrisonii Welsh is through stem cuttings. This method involves taking stem cuttings from the parent plant and placing them in a rooting hormone solution to encourage root growth. Once the roots have formed, the cuttings can be planted in a growing medium such as a potting mix or soil. It is important to keep the soil moist and the cuttings in a shaded area until they establish roots and start to grow.
Division Propagation
Division propagation of Erigeron maguirei Cronq. var. harrisonii Welsh involves separating the parent plant into smaller sections and planting them in separate containers or in the ground. This method is best done during the early spring when the plant is still dormant and the roots are easily accessible. The separated plants should be placed in a suitable growing medium such as soil or a potting mix, and they should be watered regularly.
Overall, Erigeron maguirei Cronq. var. harrisonii Welsh is a relatively easy plant to propagate through various methods, and it can thrive in a variety of growing conditions. By following the appropriate propagation techniques, you can easily grow this plant in your own garden or as part of your landscaping project.
