Extremely drought tolerant, Feathertop Grass (Pennisetum villosum) is among the most beautiful and graceful ornamental grasses with its large, fluffy, bright white flower plumes cascading down the light green foliage that rustles in the wind. While a perennial grass, it is tender and often grown as an annual. Self-seeder, it will multiply if you do not cut off the flowers before the seeds ripen in the fall

Award-winning Dahlia 'Mrs Eileen' is a magnificent Dahlia with its huge, profuse and showy vibrant orange flowers set against the lush green foliage. No wonder it won multiple awards. Just look at it! The flowers, up to 6-8 in. wide (15-20 cm) are not top-heavy because they contain little water. They remain upright and straight even when it rains. Blooming massively from July until Frost, this dahlia grows up to 36-48 inches (90-120 cm)

Hardy and reliable, Agastache 'Black Adder' (Giant Hyssop) is a charming herbaceous perennial boasting bottle-brush, terminal spikes, 6-8 in. long (15-20 cm), packed with fragrant, tubular, two-lipped red-violet flowers emerging from dark buds. Blooming from mid-summer to fall, they provide a remarkably long floral display and add color as well as a lovely spiky texture to the garden.

One of the tallest, Ageratum houstonianum 'Blue Horizon' (Floss Flower) is a frost-tender annual boasting fluffy lavender to purplish-blue flower clusters, up to 3 in. across (7 cm), from late spring to frost. Attractive to butterflies, the blossoms are borne on long, sturdy stems and float above the neat foliage mound of heart-shaped leaves. Best used for edging or borders of beds or in containers. Great for cutting.

Drought tolerant, this sweet but vigorous little plant produces a profusion of delightfully scented, large, pure white flowers that will quickly cover your beds and borders with a sea of white flowers that will beautifully mix with your other annuals or perennials. It will also cascade richly from your containers or hanging baskets and beautify your rock garden. With its incredibly long blooming season, from late spring to frost, 'Snow Crystals' forms a neat and compact mound, up to 6-8 in. tall (15-20 cm) and 10-12 in. wide (25-30 cm).
