Purple flowers can give a garden a touch of whimsy or an exotic color palette that is sure to attract the envious attention of your neighbors. And for a perfectly timed display, there are a number of June blooming varieties of purple flowers available. Those listed here sport blossoms in nearly every shade of purple in the spectrum. And whether planted as an accent or in a striking assembly of royal purple blooms, these easy-to-grow flowers are well-suited for almost any garden.
The butterfly bush is an attractive shrub that looks best when planted in the rear of a flower garden to create an eye-catching backdrop. The butterfly bush's flowers are clustered in large, heavy cones that can be purchased in nearly every shade of purple. The popular "black night" butterfly bush has blossoms that are so deeply purple that they look black from afar.
The butterfly bush flowers in June and will continue to produce purple blossoms until fall. Easy to grow and hard to kill, the butterfly bush grows well in USDA growing zones 5-10. It can be planted in any type of well-drained soil and is largely disease- and pest-free. Just give it a sunny spot, a light fertilizer in the spring and a few waterings in summer and it will reach anywhere from 3 to 15 feet in height.
For a great garden border, plant creeping phlox all around the edge of your flower garden. Creeping phlox's sweet-smelling, star-shaped blossoms come in a soft shade of light purple. This low-growing (each plant will reach 6 inches in height and 2 feet in width) creeper blooms from spring to fall, so its blossoms will be in their prime when June comes around. It is an agreeable little plant that does well in USDA growing zones 3 through 9 provided it has a sunny patch of garden and well-drained soil that has been amended with organic compost.
The iris is a classic purple garden flower prized for its vibrant hues and the unique shape of its blossoms. And like creeping phlox, irises bloom from early spring until late fall and will be in full swing when June comes around. Although they look delicate, irises are hardy plants and will grow almost anywhere in the United States.
The bearded iris, one of the most popular iris varieties, grows well from USDA growing zones 4 through 9 but has even been known to grow in the deserts and swamps of the Deep South. Irises can reach up to 3 feet in height and look wonderful in front of a backdrop of butterfly bushes, when planted en masse or as an accent. They will grow in any well-drained, amended soil and can tolerate full sun or partial shade.
For a big statement, plant delphinium as an accent flower or en masse. Most varieties of delphinium reach around 6 feet in height (although dwarf varieties are available) and produce trumpet-shaped, richly purple flowers that will be around from early spring to late fall. These tall beauties are easy to grow and thrive in USDA growing zones 2 through 9 in almost any type of soil. And as an added bonus, they attract hummingbirds which cannot resist their fragrant nectar. However, you should not partake. Delphinium is quite poisonous and can be deadly if ingested in large amounts.
