Family: Saxifragaceae

Scientific Name: Astilbe x arendsii Etna

Common Name: Astilbe Etna, Astilbe Mount Etna

DescriptionA medium Astilbe with dark red flowers.
Plant TypePerennials Hardy
Hardiness Zone4-8
SunlightPrefers semi-shaded sites, will tolerate more light if the soil is kept moist. I have a group of Astillbe in a 1/2 to 3/4 day sunny spot for over 10 years and they are a show stoppers when blooming. To achieve this they are growing in a bed that is raised a few inches and the soil is naturally constantly wet
Soil & SiteNeeds rich, humusy moist well-drained soils. Plants growing in dry conditions will be small, few blooms and tend to dry up during the hotter days in the summer.
Flowersred, mid June-third week in July
Leavesdark green, ternately compound, leaflets are coarsely serrated, foliage is an attractive feature of the plant
Dimensions24 inches tall
MaintenanceDivision of the clumps every 2-3 years will help to maintain the vigor of the plant. Astilbe are heavy feeders and need to be fertilized every year in the spring and also in the early fall. Some of my Astilbe tend to heave in the winter. In the spring I cover the exposed roots with soil, mulch or dug them in. Be careful since many Astilbe are easily pulled out of the soil
Author's NotesThe main factors to get maximum performance, are proper soil moisture, division and fertilizing.
