Helianthella

<i>Helianthella quinquenervis</i>

The clearest, brightest yellow, not at all pale and without a trace of gold, imbues the nearly 4 in. wide starry flowers of this willowy American native. Amazingly floriferous and versatile, the Aspen Sunflower is lower growing and earlier to bloom than its Helianthus counterpart.

Long, green and hirsute, straplike basal foliage blushes red come fall, while seed heads, waving on open branched sparsely leafed stalks, provide a banquet for the birds.

Originally collected in 1843 and dwelling throughout woodlands and stream sides from the “Aspen Belt” north to Wyoming and Montana, it will thrive in nearly any garden—semiarid or moist, sunny or a little shady—and makes a fine autumn bouquet with grasses and rosehips.

Blooms July – September.

Size: 3' 0" – 4' 0" high x 2' 0" – 2-1/2' wide.

Hardy to zone 3.

Our featured plant: Achillea 'Hella Glashoff'

Amazing Achilleas, Invigorate your summer plantings!

Amazing Achilleas…. These sturdy, dependable perennials produce small indivdual blooms that populate broad, flat flower heads, lending welcome horizontal elements to any garden bed. Ideal for bouquets, fresh or dried, the long-lasting blossoms range in color from alabaster to soft yellow and gold, as well as terracotta, pink and sassy red. Cut back their flowers in midsummer and enjoy a fall encore! Spicy scented, attractive fern-like green or gray-tinged foliage cloaks their strong straight stems. Slowly spreading and somewhat drought tolerant, Yarrow seem to thrive on neglect. They can handle low soil fertility plus coastal wind and salt spray. Be sure to check out our diverse on-line Achillea selections!

Invigorate your summer plantings.… A few simple maintenance techniques will help plants appear fresh throughout the upcoming dog days of summer. The addition of a chipped bark mulch or well-rotted compost, applied as a top-dressing, not only reduces water requirements, but generally makes it easier for plants to maintain perky looking leaves and vigorous habits. A July or early August trimming of long-blooming perennials, such as Nepetas and most Geraniums ensures myriad flowers that will keep on coming ‘til the first frost. Featured in this newsletter, you’ll find the fabulous plants that caught my eye as Boobah and I took our morning walk through the nursery and adjacent display borders this past week. Hopefully, you’ll have room to ensconce several of them in a well-traveled spot. Happy Digging!
