Thalictrum

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.

Thalictrum ‘Elin’   

Loosely garbed in striking steely blue foliage, ‘Elin’s tall purple-tinged stems maintain a stately carriage. An impressive hybrid between Thalictrum flavum var. glaucum and Thalictrum rochebrunianum, its sturdy upright stalks culminate in open sprays of bicolored pale yellow and lavender flowers. Known to grow up to 12 ft. tall, this lofty Thalictrum paints soft smoky hues in the background and seldom needs staking.

Blooms July–early August.

Size: 8' high x 2' wide; hardy to zone 5.

Thalictrum aquilegiifolium ‘Thundercloud’     

The species epithet alludes to the stylish, loosely tailored pedestal of blue-green Columbine-like foliage. Racing upward, numerous tall branched stems house the glaucous lavender-infused leaves, and later elevate dark purple buds. Petite, powder pufflike double flowers with fluffy, pronounced stamens in rich rosy purple shades form soft lilac clouds, casting fanciful accents on Stipa arundinacea’s low mounding form.

Blooms May–June.

Size: 3'–4' high x 12" wide; hardy to zone 5.

Thalictrum delavayi ‘Hewitt’s Double’   

Pale purple double flowers with yellow eyes adorn this Thalictrum’s tall flower stems. We often grow ‘Hewitt’s Double’ among other plants, such as Anemone x hybrida ‘Andrea Atkinson’, for support, especially in areas exposed to summer wind and rain.

Blooms August–September.

Size: 4'–6' high x 3' wide; hardy to zone 5.

Thalictrum flavum ssp. glaucum   

You will never “rue” planting this winning European native. As it emerges in spring, tender mauve-tinted stems and foliage scramble skyward. By midsummer, gleaming and glaucous trilobed, silvery blue-green foliage adorns brawny upright stems. Erect, gossamer-like panicles of soft yellow burst upward in a frothy show.

Absolutely striking when planted in a drift with Phlomis russeliana and Spodiopogon sibiricus.

Blooms July–August.

Size: 5'–6' high x 2' wide; hardy to zone 5.

Thalictrum flavum ssp. glaucum ‘Illuminator’   

Recently introduced from Holland, ‘Illuminator’ makes a dramatic entrance each spring as its strong blue-green stems and uniquely colored young foliage soar to elevated heights. Wavy edged, Columbine-like leaves unfurl with a luminous chartreuse cast, maturing to a glaucous green. Effervescent clusters of tiny yellow flowers crest this dignified Thalictrum, while its airy delicacy stands in sharp relief to bold-leafed plants such as Ligularias, Acanthus or Rheums.

Blooms July–August.

Size: 5' high x 2' wide; hardy to zone 5.

Thalictrum rochebrunianum   

A marvelous perennial that fashions an ethereal, lavender-hued mist, this elegant Japanese native boasts attractive foliage and a bounteous display of dainty flowers. Tall stems hold glabrous, blue-green, oval-shaped leaves, and each produces wiry branched blooming panicles. Prominent pale yellow stamens and persistent sepals accentuate the display. Most effective in a drift, place wherever a glow of purple would be welcome.

Blooms August–September.

Size: 5' high x 2' wide; hardy to zone 5.
