Buttonbush Flower Visitors
RANGE: This shrub is often a denizen of sunny edges of swampy woods and so it is
surprising to find it growing along washes or riparian habitats in the Sonoran
Desert. For sure, its presence indicates a pretty good water supply that may be
below the surface. It can be found in wetter canyons of the
Superstition Mountains and near Mesquite Wash.
This plant is classified as an obligate wetland species. Canyons where this plant occurs need to be protected as such because wetlands,
despite their rarity,
are vital to the Sonoran Desert ecosystem.
Each flower has four to five teeth in the rim of the tube and a long exserted style and stigma.
