Sneezeweed
Sneezeweed is a tall, upright perennial flower with sturdy stems. It blooms in late summer to early fall. The flowers come in a variety of colors, mostly yellow, orange and red. The green leaves are lance-shaped and borne the length of the branched, winged stems.
Sneezeweed is a good choice for a taller, late-blooming flower for the Pikes Peak region, provided it will get regular moisture.

Performance
Sneezeweed has been grown in the moderate water zone at the Water Wise Demonstration Garden. This area was renovated in 2012. The flowers were very attractive at full bloom.
In nature, sneezeweed grows where it is moist, so regular moisture will produce the best growth and flowering.
Maintenance
Cut plants to the ground in fall or early spring before new growth starts. Divide clumps as needed to maintain vigorous blooming. Plants may be pinched back during the early growing season to produce more compact plants with more flowers.
