Elegant Blazing Star

Liatris elegans needs watering only when the soil is dry in summer. During the winter months, it needs little water and can survive on rainfall alone. Watering should be done during the very hottest months. If possible, water in the morning so that the moisture won’t evaporate in the hot afternoon temperatures.

Liatris elegans prefers full sun and filters or afternoon shade. If placed in an area with too much shade, it will produce fewer flowers. Direct sunlight is ideal for the best flower production, but if grown in harsh conditions, a few hours of afternoon shade can be beneficial for the plant's health.

Liatris elegans will thrive in temperatures between 10°F to 90°F (50°C to 32°C). It can survive a few degrees below freezing, but it is susceptible to frost damage. It should not be subject to temperatures above 95°F (35°C) for any length of time.

Liatris elegans tolerates moderate humidity levels but prefers lower levels. It will generally thrive in humid environments, but can become stressed if humidity levels are too high. When stress from high humidity levels has occurred, the plant can be pruned or repotted in a smaller container with drier mix to lower humidity around the plant.

Liatris elegans prefers well-drained, sandy soils with a neutral to slightly acidic pH. Add some organic material such as compost or peat moss to the soil to help retain moisture. It is important to provide the plant with the right balance of nutrients to ensure healthy growth.

Fertilize the Liatris elegans in early spring and again in midsummer with a slow-release, balanced fertilizer. For best results, combine the fertilizer with water so that the fertilizer can be applied to the root zone. Regular fertilization will ensure the plant grows large and strong, and produces plenty of beautiful blooms.

Generally, Liatris elegans is pest and disease free and does not have any major problem insects. However, several common pests can occasionally appear. Aphids, thrips, whitefly, spider mites, and mealybugs are the most common. To control these pests, a sharp jet of water can be used to wash them off the leaves. Insecticidal soaps are also an effective control, as are horticultural oils. Be sure to follow product instructions when using these materials.

Liatris elegans requires repotting only once every two or three years. The best time to do this is in early spring, before new growth appears. Use a high-quality potting soil and a pot that is only one size larger. You may consider adding perlite for better drainage. Fertilize the soil with a balanced fertilizer when repotting.

Pruning is not essential, but it does help to keep the plant healthy and prevent overgrowth. If needed, prune blazing star in late spring, before flowering. Prune to the desired size or shape after the plant has reached its full growth. Avoid cutting the stem with a pruning shears as this may cause damage and will reduce the health of the plant.

Proper mulching is a great way to keep the soil moist and protect the roots from extreme temperatures. An organic mulch like shredded bark or wood chips is ideal, as it also adds in additional nutrients. Make sure to leave enough space between the mulch and the base of the plant to allow for air circulation and root growth.

Propagation of Liatris elegans is best done with stem cuttings taken in late summer when the plant is dormant. Take several 4- to 6-inch stems and cut each one into two- or three-piece sections. Place the sections in a well-draining potting mix and keep the pot in bright, indirect sunlight. Keep the soil evenly moist, but not soggy, and the stems should root in about four weeks.

Some supports may be necessary to keep the tall flower spikes from toppling. A thin stake placed in the soil near the plant’s center and tied to the top of the stem is usually the best option. Be sure to put the stake in the soil before the plant has fully bloomed, to ensure it is stable enough to support the top-heavy flowering stem.

In late summer, as temperatures drop, the Liatris elegans will enter a resting period and cease flowering. To maintain the health of the plant, protect it from any frosts or freezes and do not water it during this period. The rest period will last about 8-10 weeks before the plant begins to bloom again.

Liatris elegans is not known to be toxic to pets. However, due to its fibrous nature, it is best to keep it well away from small pets and children.
