Variety description

10 August 2026

The Campbell CW4 variety is a breeding form of heartnut. The tree is characterized by a compact crown type and produces medium-sized fruits.

The plant is protogynous: its female flowers bloom earlier than the male ones, which is why the tree requires other pollinator varieties for successful fruit set.
