Blanket Flower is a short lived perennial that is a hybrid, but blooms nearly the entire growing season from Early Summer until frost. It is a cross between two species in the Gaillardia genus. Gaillardia Aristata and Gaillardia Pulchella randomly cross bred in a garden in Belgium back in the 1800’s to produce Gaillardia grandiflora (Blanket Flower). A beautiful perennial that is widely grown today in gardens.
Will Blanket Flower Take Over my Flower Bed?
Blanket Flower will spread via seed. I’ve grown this flower for years in various flower beds and wildflower gardens. Each bloom will produce numerous seeds that resemble bad-mitten birdies. These seeds will be blown around by the wind, and frequently germinate the following Spring.
So, yes – Blanket Flower will spread by self-seeding. Depending on how crowded a flower bed is, and the available competition, you may have dozens of volunteer seedlings each year.
I have some pictures below that illustrate the potential spread of Blanket Flower, these are all volunteers that showed up in the second year.


How to control Blanket Flower?
The roots of Blanket Flower are quite short. This makes it very easy to pull up by the root as long as the soil is somewhat moist. So, early Spring is a great time to remove unwanted seedlings.
Additionally, if you grow Blanket Flower where there is some competition present, the seeds will have less available sunlight to germinate. Also, the plants will have to compete with the other flowers for available sunlight, limiting Blanket Flower’s spread.

By planting Blanket Flower in front of taller flowers, you will reduce the likelihood that the plant will spread amongst the taller plants. This effectively limits the available area for the unwanted seedlings to germinate/spread.
