How Long Until Bluebonnet Seeds Germinate?
Bluebonnet seeds germinate in about 10 days. Growers commonly scarify the bluebonnet seeds using sulfuric acid or a metal file to roughen the surface. Scarification allows for better seed-to-soil contact to promote germination. Bluebonnet seeds may lie dormant in the soil for many years until optimum conditions promote germination.
