Seasonal Garden Plants

August is an important month in terms of seasonal garden plants as it marks a major transitional period in the garden. Plants are a good barometer of seasonal changes in your garden, because there is an internal clock inside of plants which triggers autumn flowering and is an indication of the approach of fall.
The cardinal flower, for example, provides a good indication of when summer is peaking. The brilliant red flower grows in wet marshlands and new mountain streams in the wild. It is a favorite of hummingbirds, which makes it a natural favorite of many gardeners as well. These plants can make an attractive addition to larger gardens, and the same goes for asters which add fantastic color to late summer gardens but tend to spread out and hog a lot of space.
