Texas Bluebonnets are the Official State Flower of Texas. They are an annual and have a hard, thick coated seed. The best time to plant bluebonnets is in the fall, between September and November. They will germinate then stop growing during the cool season, then come spring time they will fully grow out and produce a flower.
Planting depth: 1/4 inch deep. This gives the seed the benefits of having the shortest distance to travel to the surface while also being deep enough to keep moisture.
Landscape Planting Rate: 1-2 lbs. per 1,000 square feet.
1 lb. should cover about 500 square feet. The flowers will be densely together.
1/4 lb. covers about 312 square feet.
Rangeland Planting Rate: 15- 30 lbs. per acre (1 acres is 43,560 square feet). The flowers will be more spread apart. If you wish for denser cover, plant more heavily.
Best Time to Plant: Early August through October.
Type: Warm Season Annual
