This hard-working group of perennials does so much. They bloom for a long time in wonderful colors atop tall, striking plants. They produce a nectar that is irresistible to hummingbirds and butterflies. Most are heat and drought tolerant. And their foliage and flowers are fragrant, with scents ranging from licorice to bubblegum.

Most require well-drained soil and prefer full sun, although they will tolerate light shade.

Globe thistle

Globe thistle is one of the most elegantly colored plants around. It has fantastical large blue balls of steel blue flowers in midsummer, which would be enough. But making it even more lovely are its large coarse, grayish-green leaves, which set off the flower beautifully.If you can bear to separate them from the foliage, globe thistle makes a great cut flower, lasting for weeks in the vase. It also dries well. It's bothered by few pests or diseases. If it likes its conditions, it will reseed fairly readily. If you want to prevent this, deadhead flowers shortly after they fade.


Looking like a miniature hollyhock, malva produces pretty flower spikes in blue, pink, purple, or white. It also has attractive heart-shape foliage and is useful among shrubs, in wild gardens, and in mixed borders.These short-lived plants self-seed but generally do not become invasive. Staking may be required in windy places. Mallows are not fussy about soil, but they do need full sun to do well.


Easy and undemanding, veronicas catch the eye in sunny gardens over many months. Some have mats with loose clusters of saucer-shaped flowers, while others group their star or tubular flowers into erect tight spikes. A few veronicas bring elusive blue to the garden, but more often the flowers are purplish or violet blue, rosy pink, or white. Provide full sun and average well-drained soil. Regular deadheading extends bloom time.
