Presenting a mosaic of warm colors with its flowers of various ages, Achillea 'Walther Funcke' is a strong, sturdy and gorgeous Yarrow with masses of long-lasting clusters of brick-red flowers fading to terracotta and then creamy yellow. Its pleasantly aromatic, semi-evergreen, green-gray fern-like foliage is disease resistant and nicely compliments the cheerful flat umbel flowers. The honey color of this Achillea is perfect for both cool and warm borders.

Free-flowering, Agapanthus 'Northern Star' (African Lily) is a striking herbaceous perennial boasting showy rounded clusters of dark blue, star-shaped flowers from mid to late summer. They rise on stiff, upright stalks atop clumps of beautiful, deciduous, glossy green leaves tinged with deep violet at the base.

One of the cold-hardier New Zealand Hairy Sedges, Carex testacea forms a low, cascading mound of narrow, arching, olive-green leaves turning coppery-brown in summer and adding warm, orange tints in winter. Inconspicuous brown flower spikes are produced in early summer whose stems droop gracefully as they age. Evergreen, this clump-forming perennial grass is valuable for its year-round appeal and regarded as one of the most beautiful ornamental grasses for the garden, where it provides a lovely contrast with other plants, mulch or gravel.

A stunning Heirloom selection, Hemerocallis 'Bonanza' is an indefatigable midseason Daylily that produces an abundance of fragrant, rich golden-yellow flowers with a contrasting deep purple eye. Blooming from mid to late summer, this clump-forming deciduous perennial grows up to 34 in. tall (85 cm) and spreads slowly via rhizomes to 18-24 in. (45-60 cm). This diploid Daylily is dormant (deciduous) and regarded as an all-time favorite for perennial gardens.
