One of my favorite plants began blooming this week, Lacy phacelia, Phacelia tanacetifolia, so I wanted to take a moment to tell you all about Lacy Phacelia. It has many common names including lacy scorpionweed, tansy leaf phacelia, blue tansy, purple tansy and my favorite, bee’s friend. Clusters of light blue-violet flowers that unfurl in a fiddlehead shape sit atop attractive fern-like foliage. Reaching heights of 1-3 feet and blooming for 6-8 weeks this fast-growing wildflower is an excellent addition to any garden. It also makes an excellent cut flower. 

Native to the southwestern United States, this easy to grow annual does well in hot, dry conditions but easily adapts to a variety of site conditions. Lacy phacelia seeds germinate readily in 15-30 days. Sow seeds early in the spring while there is still a possibility of frost. Ideal soil temperatures for best germination are between 37-68 degrees F. Press seeds gently into the soil at a depth of ⅛-¼”. 

It’s not only the lovely blue-violet flowers that make lacy phacelia one of my favorite plants. Lacy Phacelia is well known for its ability to attract bees and butterflies to an area. It is a heavy nectar producer and is listed in the top 20 pollen-producing flowers for honeybees. Having this source of high-quality nectar and pollen means you’ll be attracting many native bees, bumblebees, honey bees and butterflies to your garden. I have these flowers growing near my front porch and just this week I counted 4 different varieties of bees on the few flowers that just started blooming.

Trying growing lacy phacelia near your vegetable garden to increase your yields. 

Lacy phacelia also does well in containers. These containers can then be moved to different areas of the garden that need pollination. The benefits of Lacy phacelia as a cover crop are becoming more popular. It is widely used in Europe as it aggressively outcompetes weeds and absorbs excess nitrates and calcium from the soil. But it’s most important contribution is its pollinator-attracting power. 

Lacy phacelia readily self sows so removing flower heads before they set seed helps limit any unwanted volunteers. Though when you see these beautiful flowers and how many pollinators they attract to the garden you might want to let a few of these wildflowers go to seed.
