Also called stonecrop, sedums are hardy flowering plants with succulent leaves, a spreading growth habit, and tiny, star-shaped blooms. One of the most common, 'Autumn Joy', is a staple in fall gardens around the U.S.
"Pollinators enjoy sedum flowers," Smith says. "However, the sedums often found in gardens are non-native. The ornamental sedum tends to be aggressive and will start a whole plant if a leaf drops to the ground in unwanted areas."
Janney agrees. "Sedum tends to lack the visual excitement that we find in other plants during this vibrant season," she says. "There’s no movement or softness, and the color is very muted."
Instead, Smith recommends planting blue mistflower for similar visual interest in fall, or opting for native creeping varieties of sedum as groundcover.
