The Lacy Phacelia (Tanacetifolia) has green foliage and inconspicuous blue flowers, with a moderate amount of conspicuous brown fruits or seeds. The greatest bloom is usually observed in the early spring, with fruit and seed production starting in the spring and continuing until spring. Leaves are not retained year to year. The Lacy Phacelia (Tanacetifolia) has a short life span relative to most other plant species and a rapid growth rate. At maturity, the typical Lacy Phacelia (Tanacetifolia) will reach up to 4 feet high, with a maximum height at 20 years of 0 inches.

The Lacy Phacelia (Tanacetifolia) is usually not commercially available except under contract. It can be propagated by seed. It has a slow ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below 52°F. has medium tolerance to drought and restricted water conditions.
