Use the plant water needs as a guideline. Actual plant water needs will vary for several reasons, including weather conditions, soil type, sun exposure, root depth, wind and elevation. Adjust your watering schedule as needed to meet the plants' needs at your site. Water recent transplants more often than established plants.

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.
Sneezeweed has been grown in the moderate water zone at the Xeriscape 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.
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.
