Gardeners' Notes:


On Aug 18, 2014, MorelCottrill from Dunn, NC (Zone 8a) wrote:

The rust-and-gold flowers of this sneezeweed are delightfully autumnal, and I can't imagine my fall border without it now. Mine began blooming in late June this year, and last year it bloomed until the heavier frosts.

The only drawback of this plant is its susceptibility to aphids. Mine was attacked in mid-July, the only plant in my garden (even with roses galore) to be targeted. I did not address the problem soon enough, and it died back to the ground. Now it has sprouted up freshly again and might even bloom this fall, albeit a bit late.

Definitely plant sneezeweed! It's one of my top five perennial picks for autumn (along with goldenrod, chrysanthemums, asters, and willow-leaf sunflower). Just keep a weather-eye open for aphids.

Tall plant producing dozens of multi-colored flowers, that seems to party at the streets of New Orleans as the name suggest.
Fast growing till frost. Flowers on new basal branches or new shoots if deadheaded.

Tall 36-40" - Plant 18" apart. zone 4-8. Produces a riot of multicolored blooms for six to eight weeks in summer, from late June to early August. Yellow petals, lavishly splashed with orange red, form wildly patterned stiff skirts around deep brown, mounded center cones. The "tie-dyed" flowers are 1 to 2 inches in diameter. A Blooms of Bressingham selection.

General Information
A good backbone plant for the late summer and fall border.

Mine has not been as nearly as tall as described : 2 - 2 1/2' tall. The earliest blooming of my varieties. Nice compact plant.
