Spiraea douglasii

Also Known As - western spirea
Rose Spirea (Spiraea douglasii) is a perennial flowering shrub found across North America and parts of Siberia. It is known for its showy upright arching branches that can reach up to 6-feet tall and wide when mature. The plant has slim, light-green foliage and striking, fragrant light-pink flowers that bloom in late spring and summer. It requires full sun and moist, well drained soil for abundant blooms. This shrub is often used in borders, foundations, and to create layered effects in gardens. Its hardiness and drought tolerance make it a great addition to any landscape.

watering

Rose Spirea should be watered deeply and infrequently. Water your Rose Spirea about once a week and increase the frequency of watering during periods of excessive heat and drought. To water Rose Spirea, soak the soil until it is thoroughly wet. Allow the top couple of inches of the soil to dry out between waterings and when temperatures are very hot, water more often. In general, Rose Spirea should be kept evenly moist but not wet or soggy.

sunlight

Rose spirea (Spiraea douglasii) grows best in full sun, meaning at least 6 hours of direct sunlight throughout the day. It prefers direct sun during the morning and early afternoon, with some shade during the hottest part of the day. It is best to site the plant in a location that provides indirect late-afternoon sunlight, as this will help extend its flowering capacity. While its flowers may survive light shade, growth and flowering will be reduced if it does not receive enough direct sunlight.

pruning

Rose Spirea should be pruned annually during late winter before the start of new growth. Pruning should be done by removing 1/3 of the oldest, longest stems at the base of the plant. This will help promote new growth and rejuvenate the plant. It is important to use clean pruning tools and make sure that each cut is clean and angled. This will help reduce disease and pest damage. Remember to consider the overall shape and balance when pruning.
