About Zone 7 Wildflowers
Most wildflowers grow easily from seed and wildflower seed mixes are readily available. If seed mixes are the route you plan to take, it’s a good idea to do a little research on each wildflower that is listed on the package. One region’s wildflower can be another region’s invasive weed. Wildflowers can quickly spread by self-seeding, naturalizing, or forming colonies through vast root structures. Wildflowers can also be annual, biennial, or perennial, and this can depend on what zone you’re in. Knowing about the plant’s needs and habit can prevent a lot of trouble down the road. In northern climates, wildflowers are typically planted from seed in the spring, so perennial wildflowers will have all summer to grow vigorous roots, and annual or biennial wildflowers will have all season to complete their life cycle. In hot climates, wildflower seeds are usually planted in autumn as the cooler, wet weather of fall and winter aids in their germination and root development. Most zone 7 wildflowers can be planted in spring and/or autumn. September through December are excellent times to plant zone 7 wildflowers.
