Wee Bit Innocent Bigleaf Hydrangea

Wee Bit Innocent® ('SMNHMC') is a compact, mounded, deciduous bigleaf hydrangea grown for its doubled mophead florets. It reaches about 24 inches tall and 30 inches wide, with pastel pink, blue, or purple flowers in summer and a light repeat in fall ([breeder profile](https://www.provenwinners.com/plants/hydrangea/wee-bit-innocent-bigleaf-hydrangea-hydrangea-macrophylla), [patent record](https://patents.justia.com/patent/PP35815)). ## Garden placement The breeder recommends part shade or sun and lists USDA Zones 5–9. Use it in borders, containers, mass plantings, cut-flower displays, or as a focal plant; its container role is listed as a thriller ([cultivar details](https://www.provenwinners.com/plants/hydrangea/wee-bit-innocent-bigleaf-hydrangea-hydrangea-macrophylla)). ## Growing conditions Flower color responds to soil pH, with pinker tones in neutral or alkaline soil and blue or purple tones in acidic soil. The breeder rates water needs as average and prefers fertile soil. The species guide recommends good drainage for bigleaf hydrangeas ([NC State Extension](https://plants.ces.ncsu.edu/plants/hydrangea-macrophylla/)). ## Maintenance Avoid routine pruning; the breeder advises leaving bigleaf hydrangeas unpruned when possible and removing winter damage only after spring growth clarifies which stems remain viable. Keep soil moist while allowing extra water to drain ([breeder care notes](https://www.provenwinners.com/plants/hydrangea/wee-bit-innocent-bigleaf-hydrangea-hydrangea-macrophylla)).
