Tuff Stuff Red Mountain Hydrangea

Tuff Stuff™ Red is a compact mountain hydrangea with a rounded, mounded shape and large lacecap flowers. Its blooms open in green and red tones, deepen to pink-red, and may shift toward purple as soil pH changes; flowers recur on old and new wood from early summer into fall. ## Landscape Use At a mature 2–3 ft tall and wide, it fits the front of a mixed border, a container, a low hedge, or edging; group it for repeated color. The flowers also work in cutting gardens and as a dried display. See the [Proven Winners plant profile](https://www.provenwinners.com/plants/hydrangea/tuff-stuff-red-mountain-hydrangea-hydrangea-serrata) and [Spring Meadow Nursery profile](https://springmeadownursery.com/plantfinder/tuff-stuff-red-43850). ## Growing Conditions Give it part sun to sun and moist, well-drained soil. It needs average water and should not sit in soggy ground. In warm regions, afternoon shade helps protect foliage. For species-level guidance, [NC State Extension](https://plants.ces.ncsu.edu/plants/hydrangea-serrata/) recommends fertile, moist, well-drained soil and light to open shade in warmer settings. ## Selection Details Spring Meadow Nursery breeder Tim Wood developed the cultivar ‘SMNMAKTSR’, marketed as Tuff Stuff Red. Its large double lacecap florets have yellow-green centers, and its buds have improved frost hardiness; soil pH influences flower color. The U.S. plant patent was issued as USPP 28,672 on November 21, 2017, as recorded in the [patent record](https://patents.justia.com/patent/PP28672). ## Maintenance Keep pruning light: remove dead wood or old flower heads, and avoid hard cutting because the plant flowers on both old and new wood. If shaping is needed, prune lightly in late winter or early spring. Maintain even soil moisture, while avoiding extended sogginess.
