One of the more attractive spiraea varieties is the Japanese spiraea. It is characterized by abundant blooms that begin in mid-June and continue until the end of August. The flowers are bright pink and arranged in terminal panicles. Prune spent blooms once a week to extend the flowering period until September. The shrub propagates itself via root suckers. Japanese spiraea is as undemanding as other spiraea species. If you still want to give it extra care, provide it with slightly acidic, nutrient-rich soil and a spot in full sun. It will bloom profusely and for a long time. To maintain a compact growth habit, you can prune the shrub twice a year, though this is not necessary. If you allow it to grow freely, it will still look neat and airy. You can plant it as a specimen plant. It works well in both small and larger gardens. If you combine it with other types of flowers, you’ll be pleasantly surprised by the result.
Spiraea are hardy down to -34°C. You can also grow them in outdoor containers.
