Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

For long-lasting bright yellow flowers that sparkle in midsummer, try Allium moly. It is robust, hardy, and an excellent cut flower, naturalizing and increasing happily in the sun in most garden soils. The cultivar 'Jeannine' flowers earlier and produces larger umbels on sturdier stems.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Wormwood is useful in beds, borders, and rock gardens, and it makes an excellent foil for bright colors and dark foliage. This plant needs excellent drainage.

Berberis thunbergii f. atropurpurea Berberis thunbergii f. atropurpurea
(Red Japanese barberry)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Red Japanese barberry is a deciduous shrub with multi-season interest. Most striking are the deep reddish purple inch-long leaves. In spring, scented yellow flowers appear on arching stems. This barberry is an excellent hedge pland, and it also looks good in the middle to rear of beds and borders. Watch out for the brittle, three-pronged thorns. -Gerald Gibbens, Regional Picks: Northwest, Fine Gardening issue#120

Brachycome 'Blue Zephyr' Brachycome 'Blue Zephyr'
(Swan River daisy)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Swan River daisy's lacy foliage and small but profuse blue-purple flowers have a long season of impact in the garden. Its compact, bushy shape, pretty fragrant flowers, and gray-green leaves make it attractive from planting time through frost. It flowers so heavily that the foliage is often obscured. 'Blue Zephyr' has especially fine foliage and only reaches about a foot high. It is excellent in hanging baskets, window boxes, or other containers, or at the front of a bed or border.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Brugmansia suaveolens Brugmansia suaveolens
(Angels' trumpet)
(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Few plants evoke tropicalia quite like the Brugmansias, with their voluminous tubular flowers that drip from imposing shrubs or small trees. They look fantastic in containers or plunged into a border, and the dramatic display persists from late spring until autumn. In cooler climates, they may be brought under glass or cut back and held dormant in a cool basement.  All parts are highly toxic if ingested.

Butterflies swarm to their blooms all summer long. 'Lochinch' has extremely fragrant lilac-blue flowers with orange eyes. It is a cross between B. davidii and B. fallowiana. Its arching, mounded habit typically reaches 3 to 5 feet in one season, but can grow much taller in the deep South.
