When you plant a perennial, it will come back and bloom every year. Annuals, on the other hand, need to be replanted in the garden year after year. Whether perennials or annuals, different flowers bloom during different parts of the season. As you gain experience as a flower gardener, you will find it easier to plan your garden so as to have something in bloom all through the spring, summer and fall.
Sunflowers make a grand presentation in August with their large heads and bright yellow colors. Sunflowers also come in dwarf versions that are various shades of reds and golds.
Marigolds, zinnias and petunias are all August blooming annuals that can be strategically placed in the garden to keep it bright and pretty while the gardener is cleaning and preparing for Winter.
Early August Perennials
Keep the garden flowers bright as Summer turns into Fall with Echinacea Purpurea, also called Magnus. This plant produces sturdy, purple daisy-like flowers into August.
Magnus is paired well with Black Eyed Susans, sometimes called Goldsturm. The flowers are of similar shape and size with complementary colors.
Both of these plants are sturdy perennials that like fertile, moist soil. Magnus may take a couple of growing seasons to reach its full size.
Late August Perennials
Patrinia is a tall perennial that produces numerous, small yellow flowers mid- to late August. It prefers partial sun and does not appreciate being moved or transplanted, so plant it where you want it to be for many years.
Wild Senna also produces yellow flowers in mid- to late August. It prefers full sun and moist, loamy soil. In optimal conditions, it can grow to 6 feet tall and will produce large, showy flowers.
If you prefer pink to yellow, you will appreciate Boltonia, also called Pink Beauty. Boltonia is a hearty plant that prefers full sun. It grows to 4 feet tall and produces pink clouds of small flowers mid- to late August.
