Spirea is a useful shrub that can take almost anything - drought, flooding, deep frost, city pollution, frequent physical damage as well as pure neglect. In other words foolproof. That is why it is commonly planted in public places and parks where the expected level of maintenance is close to zero. Some of them are even pretty just like this Japanese spirea.Description of the plant:
Snowmound is an eye-catching spirea with pure white flowers. They are tiny and formed in terminal corymbs, and those cover the branches almost along the whole length as if fresh snow just fell on them. A plant in full bloom looks like dazzling fireworks. Flowers open from mid May for 3-4 weeks. Deciduous leaves are mid green, oval to elliptic, shallowly serrated at margins.Nippon spirea flowers in spring so any pruning should take place after flowering - in early summer. You can cut off up to two thirds of previous year’s growth to encourage growth of new branches. It is widely soil adaptable but does best in slightly acidic, fertile, constantly moist soil in full sun. Fully hardy to about -40°C (USDA zone 3) and suitable for outdoor pots.
