Botanical gardens are like a museum of plants that change from season to season. Visiting a botanical garden is a great way to educate yourself on the wide range of flowers grown around the world. At a botanical garden, you can find highly unusual plants that would otherwise be grown and viewed in specific locations. Sometimes the gardens offer flowers visitors can take home to create their own miniature botanical garden.
Peonies are a perennial flower that grows in botanical gardens throughout the United States. This spring-to-early summer bloomer grows up to 36 inches in height and has enormous, colorful blooms. The flower colors range from red to pink to white and coral. There are also variegated peonies that have more than one color swirled together for a brilliant and unusual addition to the garden. The center of the peony is bright yellow and contrasts with the colorful petals. Peonies require well-drained and slightly acidic soils to thrive. They also prefer full sun to partial shade for a full and hardy bush. The USDA hardiness zone is 3 to 7.
Daylilies are hardy perennial flowers that add color and texture to the landscape. Daylilies are also drought-resistant, making this flower a low-maintenance plant for many botanical gardens. Daylilies are summer bloomers and grow up to 36 inches in height. Their mound-like shape is often seen lining a garden walkway or tucked within a perennial garden. The flowers of the daylily range from yellow to orange, pink and deep purple. The tall upright stems hold the large blooms heads and have draping foliage that cascades down. Daylilies prefer soils with high organic matter and thrive in full sun to partial shade. Their USDA hardiness zone is 3 to 9.
Rose-mallow hibiscus is often seen scattered throughout botanical gardens. These tall perennial blooms grow up to 8 feet in height and come back each year fuller and taller. Their 6- to 10- inch blooms grow in a range of colors including red, white and pink. The flower stalk on the rose-mallow hibiscus is conjoined with the leaf stalk to support the giant blooms. The leaves are narrow and egg-shaped and range from 3 to 8 inches long. They also have toothed edges. Rose-mallow hibiscus prefers moist soil and full sun to partial sun. They can be grown in containers and are sometimes seen growing in a botanical garden greenhouse. Their USDA hardiness zone is 5 to 11.
