Allium

Allium, also known as flowering onion, includes many varieties grown from bulbs or bulb-like rhizomes. They have long stems and a large ball of purple petals, making them a great candidate for fresh cut flowers. These purple flowers grow best in full sun with well-drained soil.

Purple Coneflower

A favorite of many native-plant gardeners, coneflowers are easy to grow and do well in many soil types. Purple coneflowers can grow up to 36 inches high and are a nectar source for butterflies, while songbirds feed on their seeds. These flowers do best in full sun, but can handle some shade and make a great fresh cut flower.

Lupine

You'll get an eye-catching bold pop of purple when you plant lupine in your flower garden. These pollinator-friendly flowers come in a wave of colors, including shades of purple; and they can be grown as an annual or perennial. Lupine prefers full sun, but can handle part shade. They do best in well-drained soil.

Clematis

If you're looking for purple flowers on a vine, try clematis Jackmanii. These flowers do best in USDA Zones 4 to 8 where the flowering parts of the vine are in sun to part shade, while the roots remain shaded. They can grow up to 10 feet high and have flat, cupped or bell-shaped flowers.

Mini Iris

For a burst of purple in the spring, try growing mini iris. These bulb flowers are among the earliest bloomers. They are only 4 to 6 inches tall and are deer resistant, yet provide nectar for early season pollinators. They do best in well-drained soil, in a sunny to part-shade spot in your garden.

Wisteria

Wisteria is a vigorous vine that offers a blanket of purple in the spring. This vine needs to be planted in full sun and in well-drained soil. However, planter beware: these plants may take over your space and need upkeep. They are vigorous vines that can climb easily to 30 to 40 feet.

Anise Hyssop

You'll attract plenty of bees to your landscape when you grow anise hyssop. These purple flowers are aromatic and produce abundant blooms. Anise hyssop likes sun and can grow up to 36 inches high. They prefer a sandy, moist, but well-drained soil. Their leaves can also be used fresh or dried to add flavor to salads, soups, drinks and desserts.

Purple Bee Balm

While red bee balm is a favorite in many perennial pollinator gardens, these flowers also come in various shades of purple, making them a showy, mid-summer favorite. Purple bee balm does best in full sun and can grow up to 48 inches high. And, it attracts not just bees and butterflies, but hummingbirds, as well.
