Silky phacelia (Phacelia sericea)

Silky phacelia

Also known as: Blue alpine phacelia, Alpine phacelia, Purplefringe scorpionweed

One interesting thing about silky phacelia (Phacelia sericea) is that it can accumulate more gold in its tissues than most other plant species. However, you’re not likely to get rich extracting the gold from the plant, because it only contains 12 parts per billion of gold. Still, this is much higher than what’s in the soil, which is 1.6 parts per billion.

Water: Silky phacelia thrives in moderate moisture, preferring consistent but not excessive watering, ideally once a week. Drought-tolerant, it relies on natural rainfall patterns in temperate zones, needing less care during wet seasons to maintain optimal growth conditions.

Fertilize: Fertilizing silky phacelia with balanced nutrition fosters growth and enhances blooms. Apply a diluted solution monthly during active growth, tailored to seasonal needs. Avoid over-fertilization; wear gloves and apply at the base, avoiding foliage. Conduct a soil test for nutrient confirmation before application.

Pruning: Silky phacelia features vibrant purple flowers and feathery foliage. Prune in early to late spring, removing dead or damaged stems to ensure health. Cutting back spent flowers encourages re-blooming. Regular pruning fosters compact growth; always use clean, sharp tools to avoid disease.

Propagation: Silky phacelia propagation is best achieved through sowing stratified seeds for improved germination. Use well-draining soil and plant seeds superficially, ensuring consistent moisture without waterlogging. Patience and careful attention to these guidelines support successful establishment of silky phacelia.
