Fast-growing, Anthemis tinctoria 'Kelwayi' creates mounds of finely divided, aromatic foliage, with masses of bright yellow daisy-like flowers with a mission to flower profusely throughout summer. The 2 in. wide (5 cm) flowers are slightly larger than those of the species. A prolific plant for a sunny border, 'Kelwayi' is a vigorous perennial that will add long-lasting color and contrast to the summer perennial border.

Allium sphaerocephalon or 'Drumstick Allium' is a lovely addition to the border where it adds interest and movement with its dense egg-shaped flower heads atop straight and slender stems, delicately turning from green to purple as they mature. Blooming in late spring to early summer, this spectacular bulbous perennial adds some dramatic color to the garden. Naturalizes easily and will come back year after year

With its luminous spiny collar of silvery-white bracts surrounding an egg-shaped flower head and tightly packed with flowers, initially pale green, then changing to steel-blue, Miss Willmott's Ghost (Eryngium giganteum) is quite a catch and an asset to any garden! Rising atop a basal rosette of heart-shaped green leaves, this short-lived perennial or biennial self-sows generously and remains in the garden year after year for our utmost pleasure.
