Gorgeous Spherical Flowers for the Midwest

  • Share this:

Summer gardening offers a range of amazing flower colors and textures to choose from. When combining plants for flowering, gardeners like to focus on their favorite color combinations. Although this certainly makes sense, flower architecture can add extra interest to any plant composition or landscape scene. Flower architecture refers to the shape of flowers, which can range from daisy-shaped and trumpet-shaped to spiral or spherical. All these shapes, in addition to the colors they provide, bring additional interest to the garden.

In particular, spherical flowers provide a strong texture of interest and tend to attract the eye in a composition where they stand out or may be repeated throughout the space. These flowers usually consist of inflorescences arranged in a spherical shape. The spherical flowers have strong symmetry and become very prominent at the peak of blooming. They look very eye-catching near contrasting flower shapes such as spires and daisies. Here are three excellent plants with spherical summer flowers, but there are more opportunities among annuals, perennials, trees and shrubs.

This North American native prefers dry, poor soil, which is very drought-tolerant once established. In fact, you should avoid overly fertile soil or shadows because it will become too high and soft. 1 inch diameter flowers appear in summer clusters above the yucca-like blue-green leaves. Plant heights are usually between 4 and 6 feet, although the "Prairie Moon" variety can reach up to 3 feet. These flowers have important pollination value. Master Rattlesnake is very suitable for mixing perennials and native meadows.

Globe thistle

In summer, golf-sized ball thistle flower heads float on silver-gray leaves. Extremely drought-tolerant, it grows a tap root, and if it moves or splits, the recovery speed is very slow. Avoid overly fertile soil, and be prepared to use piles to support the hovering flower bulbs. The most common species is probably the southern globe thistle (E. ritro, zones 3-8), which can reach a height of up to 3 to 4 feet during flowering. Ball thistle includes many different species and hybrids, with flowers ranging from white to all shades of blue. Be sure to pay attention to the mature height of the person you are considering. Whichever you choose, the seemingly floating flower balls of globe thistle are eye-catching.

This native shrub is becoming more and more popular and can be used in landscaping. Buttonbush likes moist soil and can tolerate very humid conditions as well as general garden soil. The native species is about 12 feet or higher and is classified as a large shrub. However, there are now many compact varieties that can reach heights of 5 to 8 feet. This shrub prefers full sun rather than partial shade. It blooms in summer and has fragrant spherical flower heads with a pincushion appearance. Buttonbush does not bloom well in full shade or dry soil. Many pollinators and other wild animals like this plant, and this plant rarely has insect or disease problems.
