While the late summer usually means the end of the road for most wildflowers, a few of the hardier varieties tend to bloom late and thrive throughout the late summer and into early autumn. Consider planting some of these varieties if you'd like to extend your garden's blooming season until around the first frost.
The daylily is a perennial wildflower that typically is among the last of the summer wildflowers to begin blooming. Though there are many distinct cultivars and variations of this flower, one trait that is common to most daylilies is the one-day life span of each bloom. Daylily stems are usually topped with clusters of buds, and one bud blooms in the morning and dies in the evening before being replaced with an entirely different bud the next day. The tendency for these flowers to continue blooming in this fashion even after being cut makes them attractive choices for flower arrangements designed to last several days. Daylilies are available in a huge range of colors.
Bearsfoot is a striking wildflower that grows slowly during the summer, often reaching heights of around 12 feet before flowering with round yellow blooms of about 2 inches in diameter. It gets its common name from the appearance of its massive leaves, which are vaguely paw-shaped, have deep vein ridges and can grow to be longer than a foot. Bearsfoot often begins blooming during the midsummer, but continues blooming throughout the late summer. This wildflower typically grows in wet, wooded areas and is a common botanical ingredient in various prescription and over-the-counter hair growth aids.
Goldenrod is a broad genus of perennial wildflowers that typically feature bright yellow, spiky blooms with thin, flexible stems. These flowers always bloom in late summer at the same time as ragweed, a much less visible wild plant that can cause powerful symptoms for hay fever sufferers. Because goldenrod is comparatively striking and ragweed so easy to ignore, it is often mistakenly blamed for causing hay fever irritation. Goldenrod is edible and sometimes used as a cooking ingredient, and in natural medicine it is sometimes used to create solutions for kidney irritation.
