Spring bluebonnets get all the glory, but there are native wildflowers that bloom all summer. Some bloom in June, some later and some bloom through September or even longer. In addition to being beautiful, native wildflowers are great plants to put in your garden. 

As a bonus, native wildflowers adapt to the amount of rainfall and are drought tolerant. Of course, you have to water them when they are getting established, but they don’t need or want much attention after that. 

There are dozens of wildflowers that will grow in Collin County. These are just ten possibilities.

How To Grow Wildflowers

Wildflowers are generally grown from seed. In our area, sowing seeds in the fall produces the best results. The plants often germinate and grow good roots in the fall, go dormant in the winter and then start growing again in the spring. Other seeds need to go through the winter weather to weaken the seed coating so the little seedling can emerge. 

Since these flowers are adapted to Collin County, they require little attention once the plant is established. Most of these flowers do not require fertilizer.  

Where To Find Seeds

Wildflowers can be challenging to obtain. In most cases, you will not be able to find plants, only seeds.

  • According to the Lady Bird Johnson Wildflower Center in Austin, Native American Seed is a source for many different wildflower seeds.  
  • Wildseed Farms near Fredericksburg has been selling native wildflower seeds for 35 years. They allow people to tour their grounds so you can see what they are growing. The farm is beautiful in the spring.
  • American Meadows sells a number of wildflower seeds and mixes. Their minimum purchase is a 1/4 pound of any particular seed.
  • Eden Brothers also sells wildflower mixes and seeds for individual wildflowers, but in smaller quantities.  

There are wildflowers that bloom from spring all the way up to winter. Pick a variety of blooms to have wildflowers all season long. In addition to not needing much care, wildflowers attract and feed beneficial insects, birds and sometimes other wildlife.
