Agastache 'Cotton Candy'
This plant is a sea of flowers. It's an easy growing, vigorous perennial that blooms from mid-summer until frost. The dense flower spikes have numerous light pink flowers. It has a compact, low branching growth habit. It tolerates dry conditions and prefers well drained soils. All Agastache are popular with hummingbirds.
Agastache 'Summer Love'
This new Hummingbird Mint has masses large red-purple flowers all summer and into fall. It forms an attractive upright mound to 36" tall and has bright green, fragrant foliage. This is a great perennial if you're in zone 6 or warmer and have good soil drainage.
Jasminum officinale 'Flona's Sunrise'
This colorful vine is a yellow version of the Poet's Jasmine vine. It is a strong climer that can reach twenty feet if you give is something to twine up. I especially like its fragrant white flowers in summer. It is hardy to zone 7 and warmer but those of you in Zone 6 might have some luck if you plant it in a protected location and mulch it each year to protect the roots.
Stokesia laevis 'Purple Pixie'My friend and trusted Perennial Diva Stephanie Cohen turned me on to this little beauty. It is the first ever dwarf Stoke's Aster! It has large violet blue flowers and a short, compact habit that does not fall apart with maturity. It blooms in early July and sporadically until fall. It's a great little plant for the areas with high heat and humidity. Hardy to zone 5, it is happiest in full sun. It's best to avoid soils that are wet or high in lime.
