Rose Verbena
From a distance Rose Verbena can masquerade as a patch of phlox; at knee level, its hairy trailing stems, rooted nodes, and opposite three-part toothed leaves give the glade plant away.
Artwork inspired by Edmund Wuerpel
Rose Verbena is a low, spreading, hairy perennial with stems that can root where nodes touch the ground. Rounded to flat-topped clusters hold many tubular rose-purple flowers with five spreading lobes. Opposite leaves vary in shape but are commonly divided into three toothed or lobed sections—foliage that separates the plant from superficially similar phlox.
In Missouri it grows statewide, especially in central and southern glades, bluff tops, rocky prairies, roadsides, and other sunny dry openings, flowering from March into November. Photograph the entire growth form before the bloom: trailing stems, paired leaves, node contact, rock substrate, and neighboring plants carry more identification evidence than a detached flower head.
- Bloom
- March–November, strongest in spring
- Growth form
- Low hairy stems that spread and may root at nodes
- Phlox check
- Opposite leaves often divided into three toothed sections
Quick guide
- Begin below the flower
- Trace one stem through opposite leaves to a node touching soil
- Keep the glade intact
- Photograph from trail or exposed rock without stepping on thin soil or crust
Separate Rose Verbena from phlox by reading the whole plant
- Frame the patch before the blossom
- Look across a Missouri glade for a low spreading mat rather than upright isolated stems.
- Trace one hairy stem
- Follow one trailing Rose Verbena stem without lifting it: find an opposite leaf pair and a node resting on the ground.
- Use foliage to test the flower guess
- Check for leaves commonly divided into three toothed or lobed sections beneath rounded clusters of narrow-tubed five-lobed flowers.
- Preserve the thin-soil community
- Use established tread or exposed durable rock for the photograph.
Good to know
The flower cluster supplies the first impression, but the stem supplies the stronger diagnosis. Rooting nodes let Rose Verbena spread laterally through dry openings where an upright plant would leave gaps.
Notice these
- Rounded rose-purple flower clusters
- Hairy trailing stems
- Nodes that root on contact
- Opposite three-divided toothed leaves
