When a plant's size is listed by height, it refers to how tall the plant is from the top of the soil line/root ball to the top of the foliage, on average.
When a plant's size is listed in gallons, it refers to the size of the nursery pot it will arrive in. This is reflective of its maturity — larger numbers mean more mature plants.
