Regarded by some as one of the very best, Allium 'Firmament' is a rather unusual Allium. Instead of having round flowerheads, it is only two-thirds of the sphere, about 4-5 in. wide (10-12 cm). It is packed with star-shaped, dark silvery purple flowers, each flower being comprised of dark purple florets adorned with shimmering silver anthers. Blooming from late spring to early summer, this striking bulbous perennial enjoys a long-lasting season of interest and remains ornamental in the garden well into summer.

Stipa tenuissima (Mexican Feather Grass) is an exceptionally lovely and graceful ornamental grass that exhibits silvery-green thread-like leaves in late spring, that sway gracefully in the slightest breeze, delicately softening any landscape. All summer, it bears abundant feathery panicles, which are held a little above the foliage and can be used in dried arrangements. Native to the Americas, this perennial grass provides a fairly long-lasting display with its airy silky green leaves turning golden brown towards fall.

Eryngium bourgatii 'Picos Blue' (Mediterranean Sea Holly) is a lovely addition to the garden or mixed containers for various reasons. Unlike other species, its deeply lobed, dark green foliage, which appears before the flowers, is elegantly marbled with broad silvery-white veins, making it very attractive and luminous. In mid-late summer, its branched stems produce extraordinarily eye-catching, cone-like flowerheads with narrow, spiny, deep blue bracts that make wonderful additions to dried flower arrangements.

Award-winning Hemerocallis 'Golden Chimes' is an outstanding early midseason Daylily that produces an abundance of small, graceful, star-shaped, deep yellow flowers, 3 in. wide (5 cm), with distinctive reddish-brown reverses. Borne on dark stems, the flowers last no more than 24 hours (thus the common name 'Daylily'), opening up in the morning and withering during the forthcoming night, possibly replaced by another one on the same scape (flower stalk) the next day. The bright green, strap-like leaves of this diploid Daylily are semi-evergreen. Winner of multiple awards.
