Meadow-Rue
Once upon a time, the newborn infant was placed upon a pillow filled with Meadow-Rue to ensure a prosperous life. Thalictrum means “to flourish,” and it does, with elegant foamlike sprays that resemble Baby’s Breath, and rounded, finely cut, compound foliage. Tougher than it appears, Thalictrum is the perfect choice for the border.
Showing amazing vigor, this exceptional Thalictrum was twice as large as the other delavayi seedlings when esteemed Dutch plantsman, Coen Jansen initially spotted it growing in a propagation tray. Glaucous bluish green Columbine-like foliage drapes the sky-high sleek dark stalks that energetically thrust upward, supporting large soft-hued effervescent puffs of plenteous lilac pink flowers with pronounced creamy yellow stamens on finely branched stems. A regal stand-alone for any garden, ‘Ankum’s hearty amber-colored spent stems maintain an exquisite presence long after its lovely blooms and leaves have faded.
Blooms July–August. Size: 6-1/2' high x 2' wide; hardy to zone 5.

Thyme
“I know a bank where the wild thyme blows,” says Oberon to Puck in A Midsummer Night’s Dream. Upright or creeping, these aromatic culinary herbs form luscious mats of ground cover or sprite-sized shrubs, embellished with miniature flowers in whites, purples and pinks. In the herb garden, or around and between stepping stones or bricks, Thymes love sun and well drained soil, and can even tolerate a dose of wind and salt spray.
This low spreading, evergreen Thyme has a lot to offer: golden variegated foliage, colorful flowers, and a tangy lemon aroma. Brimming with tiny pinkish purple blooms, the 3 to 4 in. long, flowering clusters enhance the gilt-edged, deep green leaves, which are especially bright-hued in the cool of spring. Creeping near Hebe ‘Champagne’, ‘Doone Valley’ makes a captivating, small-space ground cover.

Trachystemon
Oriental Trachystemon
Looking for a bold toughie to beautify that problem area in your garden? Trachystemon orientalis may be your answer.
Whether the spot is sunny or shady, dry or moist, or over rough terrain, this Borage family member will rapidly fill it in with a thick, weed-smothering cover of handsome, coarse textured dark green leaves—hairy, immense, many up to a foot long, and heart-shaped—attached to long petioles. Heralding spring, starry blue, white-throated flowers carried on branched hairy pink stems are reminiscent of Dodecatheon blooms and make their appearance before the wavy-edged foliage bursts forth in late spring.
Its native haunts are Bulgaria and northern Turkey, and here in our garden it intermingles with Anthriscus ‘Ravenswing’ and Euphorbia ‘Great Dixter’, creating a dynamic array of foliar colors and textures.

Toad Lily
Some say this fascinating species owes its common name to the Philippine Tasaday Indians’ practice of wiping their hands with juice from the blossoms before setting out to collect frogs. Others say it’s the unusual spotted flowers that account for the name.
Whichever story is true, the blooms have such detail and quiet beauty that they should be admired close-up. They open on gently arching stems for long periods in late summer and early fall, when most other flowers are already spent. With a moist, humus-rich soil, all the Toad Lilies will form elegant clumps.
A jewel of the shadows, velvet-smooth lily-like flowers are defined by pronounced violet anthers and creamy white and powder blue petals dramatically splashed with bluish purple flecks. Compact gently arching stems and ovate emerald green leaves forge a stylish vase-shaped base for rounded maroon buds and exotic-looking late season flowers. Inheriting hirta and formosana ancestry, ‘Blue Wonder’ needs to be ensconced along a path where its amazing detail can be easily relished.
Blooms September – October. Size: 18"–2' high x 12"–15" wide; hardy to zone 5.
