Anise Hyssop

You might be familiar with tall, spiky purple flowered anise hyssop, but did you know that it also comes in even longer blooming, knee-high varieties with feathery pink, orange, yellow and purple plumes? Poquito Orange, pictured here, and ‘Rosie Posie’ are two of the most prolific cultivars, flowering non-stop without deadheading from early summer through early fall.

It’s unusual for blooming plants with such tropical flair to be perennial, but they do return year after year in Zones 5 to 9 if they are planted in well-drained soil and full sun. Where could you use a bright splash of blooms that will bring in the pollinators?

Yellow Corydalis

Find an ideal spot where this lacy-textured, yellow-flowered beauty is happy and it will reward you with bright yellow blooms from early spring to frost every year. Few other perennials can claim such an amazing span of color, plus its fernlike foliage is pretty, too.

Despite its delicate appearance, this perennial thrives in Zones 5 and 6 in part sun to full shade, reseeding itself happily about the garden. The shallow rooted seedlings are easy to pull from any place they aren’t welcome. In Zone 7, expect yellow corydalis to bloom prolifically in spring but go dormant in the hottest part of the summer.

Festival Star Baby’s Breath

Love to cut and dry flowers from your garden? Then you need baby’s breath, specifically this one named Festival Star. Unlike most cultivars that go to seed by midsummer, it blooms non-stop from late spring through early fall — plenty to keep your vases filled all season.

In Zones 3 to 9, choose a spot near the front of the flower border in full sun and well-drained, alkaline soil. Expect this variety to mature into a 12- to 18-inch tall mound, an easy size to tuck just about anywhere in the garden.
