This species grows up to three feet tall, preferring wet soils. Various authorities state that flowers are borne on terminal racemes, but I often see axillary racemes growing sideways, as shown in the top photo.
Swamp candles are native to eastern North America, ranging from Manitoba to Newfoundland and south to Georgia; they’re also found in a few places in the Pacific northwest, apparently introduced by accident*.
Whenever I see plants like this in wild places, I wonder why they aren’t common in horticulture. This is a handsome plant with beautiful flowers that last a reasonably long time. Surely there’s some place for it in the home landscape.
