These 9 garden beauties thrive in summer heat
and bloom nearly nonstop into fall!
4. Dahlia: Bold blooms in a range of vibrant colors grow from tuberous roots.
7. Purple fountain grass: Feathery, rose-colored plumes fade to beige atop clumps of reddish brown foliage
8. ‘Moonshine’ yarrow: One of the most carefree and generous bloomers, yarrow has tight clusters of deep yellow flowers on 2-foot tall plants.
9. Penstemon: These bushy plants are fairly short lived, but to make up for it, they produce lots of trumpet-shaped blooms over a long period.
