Purple lovegrass (Eragrostis spectabilis)
Also known as: Canegrass, Tumblegrass, Spectacular Love Grass
Purple lovegrass (Eragrostis spectabilis) is a native perennial grass known for its clump-forming habit and ability to spread through rhizomes and self-seeding. The plant showcases striking purplish-blue flowers in August, which later turn brown in the fall, releasing seeds that are carried by the wind. Ideal growing conditions include:
1. **Sunlight:** Prefers full sun.
2. **Soil:** Best in dry, sandy, or rocky soils.
3. **Water:** Requires moderate watering and is drought-resistant once established.
4. **Temperature:** Grows well in warm climates, suitable for USDA zones 5-9.
5. **pH:** Adaptable to a variety of soil pH levels, from acidic to slightly alkaline.
Avoid overly rich or poorly drained soils to ensure optimal growth.

What Is the Ideal Temperature Range for Purple lovegrass?
The ideal temperature range for Eragrostis spectabilis is between 65°F and 75°F. This range provides optimal conditions for photosynthesis and growth. Maintaining these temperatures ensures that the plant remains healthy and vibrant by facilitating nutrient uptake and enzymatic activity.
What Soil is Best for Purple lovegrass?
Eragrostis spectabilis thrives in well-drained soils, which prevent water from accumulating around its roots. This drainage ensures the plant does not suffer from root rot, which can hinder growth and vitality. While not overly demanding, E. spectabilis prefers soils with moderate fertility. Adequate nutrients support healthy foliage and vibrant blooms without overwhelming the plant's natural resilience. For optimal growth, E. spectabilis benefits from aerated soils. Aeration helps promote healthy root development by allowing oxygen to reach roots, enhancing water penetration and nutrient uptake.
How to Fertilize Purple lovegrass?
Eragrostis spectabilis, or Purple Love Grass, thrives with minimal fertilization. Apply liquid fertilizer at half the recommended strength for houseplants; about one teaspoon per gallon of water per application. Solid fertilizers should be slow-release granules, sprinkled sparingly at a rate of one teaspoon per square foot.
How to Prune Purple lovegrass?
Start by removing dead or damaged stems to improve air circulation. Cut back to about two-thirds of the plant's height during spring or early summer. This encourages fresh, robust growth and also enhances flowering. Use sharp shears for clean cuts. To maintain an attractive shape, trim the grass lightly around its edges. Ensure you follow the plant's natural contour to achieve a more pleasing appearance without sacrificing its health.
How to Propagate Purple lovegrass plant?
1
Allow the flower heads to mature and dry on the plant before collecting seeds. Ensure the seeds are completely dry before storage to prevent mold growth, which can spoil the seeds.
2
Sow seeds in a well-draining seed mix, lightly covering them with soil. Ensure they are kept warm and moist, ideally in a greenhouse or under a cloche to promote germination.
3
In early spring, dig up mature plants and gently separate the root ball into smaller sections with at least a few stems each. Replant the sections in well-prepared soil and water thoroughly to help them establish.
How to Repot Purple lovegrass plant?
1
Eragrostis spectabilis should be repotted when you notice roots growing out of the drainage holes or when it becomes root-bound, which means the roots have filled the pot and are circling around the edge. This typically occurs annually or every other year. Early spring is an ideal time as the plant enters its growth phase, allowing it to establish quickly in a new pot. Being proactive before the growing season starts ensures robust development.
2
Choosing the right pot for Eragrostis spectabilis is crucial. Opt for a pot that is one size larger than the current one to give ample room for root growth. Ensure the pot has sufficient drainage holes to prevent water accumulation, which could lead to root rot. A pot that is slightly wider and shallower is great, as it mimics the plant’s natural environment, encouraging healthier foliage spread and optimal water utilization.
3
For Eragrostis spectabilis, select a well-draining sandy soil mixture. A blend that includes sand, perlite, and a bit of organic compost ensures the roots have the aeration they require while having access to nutrients and retaining just enough moisture. The benefits of such soil include minimized risks of root rot, better growth, and a structure that supports striking panicles, characteristic of this beautiful grass.
