There is actually no law that prohibits picking bluebonnets in Texas, according to the Texas Department of Public Safety.
It may take several years to establish a good stand of bluebonnets and they do require some particular conditions to thrive. But once they are going, your bluebonnets should reseed and reappear each spring.
Seed may be planted September 1 through December 15; however, for best results, plant seeds no later than mid-November. This allows seed time to germinate and grow throughout the winter months, during which time a heavy root system and a sturdy plant is developed to produce an abundance of spring flowers.
That's because it takes years for bluebonnet seeds to germinate. The plants reseed each season. The tan, fuzzy pods turn brown, fall off and seeds pop out to spread. To encourage more bluebonnets in a field, it's important to wait until at least half the pods have turned tan before mowing.. . . . .364011236300!]0000000000000009783314146920!]
