Suggested Uses

Snow White Mockorange can be used in many different sites within a landscape. The most important consideration to account for is the amount of sunlight. It is essential that the Snow White Mockorange receives at least 5 hours of sunlight a day. The plant prefers ‘Full Sun’, but can tolerate periods of dappled sunlight. Without enough light the plants’ blooms will not meet our aspirations. The moisture level in the soil is also important, being sure that the soil stays moist through the hot summer months, being careful not to over-saturate. The beautiful white flowers cascading from a large shrub make a perfect backdrop to a rose garden or any perennial flower bed. It can also act as a privacy shrub on a border, or the statement of a foundation planting.

Wildlife Value

Snow White Mockorange is fairly resistant to deer and rabbits. There may be occasional browsing, but this shrub is a lesser concern than with many plant choices. The dense branches are a good nesting spot for birds and the highly fragrant flowers attract bees, butterflies and hummingbirds. Other small critters may take shelter in the density of the branches, resulting in all-round value for wildlife.

Maintenance Tips

Snow White Mockorange is a very simple shrub to maintain. If the plant is being used in a border and has aspirations of growing tall, simply prune-to-shape after it finishes flowering. It can also be left to its’ own, in areas where the aesthetics aren’t as important, and a slightly wilder look is preferred. Pruning after flowering ensures that the buds will not have been developed yet and will not be lost. Fertilizing with a low even NPK ratio is all this plant needs in the spring, along with consistent weekly watering.
