When it comes to gardening, one of the most difficult conditions you'd ever want to face is gardening in clay soil. It drains poorly, is low in oxygen, becomes compact as a result of its small particles, and makes it almost impossible for roots to work their way into the soil.
Clay soil contains less sand and silt compared to other soils. But you can work on improving clay soil composition over time to suit your plant or crop requirements. Alternatively, you can utilize your garden by planting perennial plants that thrive under conditions supported by clay soil. Here are some examples of the best plants to grow in clay soil:
Black-Eyed Susan (Rudbeckia Hirta)
Black-Eyed Susan easily thrives and grows in clay soil. Though it's known to reach heights of 3-4 feet and is typically common to Zone 4, the golden flowers of this perennial plant reseed and spread with ease. This enables it to bloom from summer through fall and also attract butterflies.
This plant is considered a darling in gardens. Its flowers come in an assortment of colors that attract butterflies to its feathery foliage. It is common to Zone 3 and easily grows to different heights. Yarrow is resistant to deer and rabbits, and in dry weather it reserves its bloom until later in the season.
Rattlesnake Master (Eryngium Yuccifolium)
As its name suggests, Rattlesnake Master is considered to be an antidote, and is commonly used by Native Americans for rattlesnake venoms. It is common to Zone 4 and grows 3-4 feet, developing greenish-white or bluish-white flowers that you will find irresistible in your clay garden.
Aster (Aster Novae-Angliae)
If you are the kind of person who fancies beautiful gardens in fall, this plant is a perfect fit for your garden. Aster is common to Zone 4 and grows 1-5 feet tall, though other varieties may grow to impressive heights. Its flowers come in different colors, making it attractive to butterflies.
Flax (Linum Perenne)
Flax grows 1-2 feet in height and is common to Zone 5. Its flowers bloom in spring or summer.
