We do not have a specification for "cut flowers" in our Native Plant Database, and most of the lists we found on the Internet were either non-natives or hybrids, or both. So, we are going to search our Recommended Species for Central Texas and see what we can find that will be in bloom at different times of the year that could work. Our Flower Volunteers, who regularly make the arrangements you will see around the buildings at the Lady Bird Johnson Wildflower Center, often use grasses, branches with berries on them, and foliage cut from plants that are not flowering right at that time, so you could use some creativity there and we will try just to locate some flowers you could grow for your arrangements. We are going to separate our lists by "annual," "perennial," and "biennial." Often, while annuals will bloom and reseed themselves the first year, perennials and biennials will not bloom until the second year.  Follow each plant link to find out more about the sun requirements, water needs, etc. Since we do not personally have much experience with cut flowers, we tried to select only flowers that had long, fairly sturdy stems and showy blooms. From your own experience, you can choose which will work best for you.
