HORTICULTURAL
Plant Sale Text: Common sneezeweed thrives and blooms prolifically in the heat and humidity of late summer. Moist soil is ideal for this perennial, although it will perform well in average garden soil. Named "sneezeweed" because it blooms at the same time as the ragweed that causes allergy symptoms. This perennial provides a glorious show of yellow flowers. Cut foliage back after flowering to get second bloom. Natural rabbit repellant.
