Lacy Phacelia is a fast-growing flower that produces abundant clusters of lavender-blue blooms. It grows well in hot and dry conditions and is especially adapted to the southwestern states. It blooms throughout the summer months and prefers full sun. Plants can reach 48″ tall and the flowers are very attractive to bees, butterflies and other pollinators. It has been listed in the top 20 pollen producing flowers for honeybees and also attracts bumblebees and hoverflies. The stamens project outward far beyond the petals to give this flower a beautifully unusual appearance.

Lacy Phacelia is also very beneficial when grown as a cover crop for the vegetable garden. It quickly forms mycorrhizal fungal associations to improve soil biology for future vegetable crops. It has an elaborate root structure which can penetrate as deep as 30″ in some instances. This makes it a great option for improving aeration and workability in hard, clay soils.

Lacy Phacelia is a nitrogen scavenger and has been reported to scavenge up to 15 to 20 units of nitrogen per acre. It has a dense foliage which forms a carpet over the soil to retain moisture and prevent erosion. The dense foliage decomposes quickly once cut or tilled and adds carbon and organic matter to soils. Lacy Phacelia has also been noted to reduce harmful nematode populations. In milder climates, it can be grown as a fall/winter cover crop because it can withstand temperatures down to 18 degrees Fahrenheit.

Lacy Phacelia can be transplanted or direct-seeded. For cut flower applications, transplanting is favorable. This flower variety grows great in our heavy-duty seed starting trays with Pro-Mix Organic Seed Starting Mix. Place 1-2 seeds per cell and dust lightly with finely-ground seed starting mix. Once seedlings emerge, thin to one seed per cell.  Transplants are ready to go in the ground when they can be easily pulled from the seed trays. For cover crop or soil-building applications, direct-seeding is preferred. Be sure to terminate the cover crop shortly after flowers appear to prevent reseeding in the vegetable garden.
