The taller hybrids come in richly colored elegant spires, great for cutting. Delphinums are early summer blooming perennials. Zones vary. Full sun, plant in rich soil
PINKS (DIANTHUS): There are over 300 species and lots of hybrids available. I love these adorable cottage type perennials. Main blooming season is spring into early summer, but many varieties rebloom later in the season if faded flowers are removed. Plant them in light shade in hot climates. Zones 1-24.

Great in perennial borders and beds and also with all kinds of roses. Afternoon shade in very hot climates otherwise full sun. Zones vary.
CATMINT (NEPETA): The most popular Nepeta variety is “Walker’s Low”. Early summer to midsummer gives the best flower show. But if you shear off the spent flowers you will have another flower show that will last all summer. As a group, catmints are recommended for zones 3 to 8.
CORAL BELLS (HEUCHERA): They are compact evergreen perennial plants. Many are grown for their colorful foilage. The bloom time varies from late spring through summer, some bloom into fall. I like their slender stems with dainty clusters of flowers. Grow in part shade, full shade or full sun in colder summer climates.
