One standout for sunny gardens is Lavender, a fragrant perennial shrub loved by gardeners and pollinators alike. Hardy from zones 5 to 9, lavender thrives in full sun and well-drained, slightly alkaline soil. It’s perfect if you want a plant that offers beauty and a wonderful scent, you can harvest for culinary uses, or sachets.
Quick tip: Don’t forget to prune it back after flowering each year to keep the plant compact and encourage fresh growth.
Allium

If you want a tall, dramatic display, Allium giganteum is a fantastic choice. These globe-shaped purple flowers atop long stems add architectural interest to any garden. Alliums grow best in zones 4 to 9 with full sun and well-drained soil.
They’re bulbs, so plant them in the fall, and they’ll return year after year, adding late spring color and attracting beneficial bees.
Mini Iris

For those with limited space or who prefer early blooms, the petite Mini Iris bursts into view in early spring with rich purple flowers only a few inches tall. Hardy in zones 5 to 9, these bulbs prefer sunny to partly shaded spots with well-drained soil. Plus, their early flowering helps feed hungry pollinators emerging after winter.
Clematis

If you’re looking to add vertical interest, the Clematis jackmanii vine is a showstopper with its large, flat, purple flowers. It flourishes in zones 4 to 8, loving sun on its flowering parts but cool, shaded roots — so mulch is your friend here.
Clematis can climb up to 10 feet or more, perfect for trellises or fences. Regular pruning based on variety helps keep blooms abundant.
Wisteria

Another vigorous climber to consider is Wisteria, which drapes your garden with cascading purple blossoms in spring. Suitable for zones 5 to 9, it needs full sun and well-drained soil.
Be warned — Wisteria is a powerhouse that requires regular pruning to prevent it from overtaking your space, but the fragrant, beautiful flowers are worth the effort. Also, opt for the less invasive native options, not the Japanese one.
Purple Coneflower

For perennial garden charm, Purple Coneflowers (Echinacea purpurea) are tough, drought-tolerant favorites in zones 3 to 9. These native beauties attract butterflies and songbirds, providing summer-long interest with their daisy-like purple petals and prominent seed cones.
Maintenance Tip: Deadheading keeps the blooms coming, and in fall, birds appreciate the seeds.
Lupine

If you like a bit of flair and color diversity, Lupines add stunning spires of purple to the garden. Depending on the species, lupines may behave as annuals or short-lived perennials, thriving in zones 4 to 8. They prefer full sun but tolerate some shade and flourish in slightly acidic, well-drained soils.
Bonus: They fix nitrogen, improving your soil naturally!
Anise Hyssop
