When to plant Texas Bluebonnet
A winter annual sown from seed in August in full sun (8 to 10 hours of direct sun) and any well-drained soil; it will not perform in poorly drained clay or shade. Lightly cover or rake the seed into the soil and keep it slightly moist; peak bloom comes in late March and early April.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
