Astilbe is a dense, bushy perennial, notorious for its leafage and stunning flowers.
Key Astilbe facts:
Type: flower, perennial
Height: 1-3 ft / 30-100 cm (variety)
Exposure: shade or part sun
Soil: heath soil – Flowering: April to May
Its elegant and ethereal inflorescence also dresses the garden in hues of white, pink, and even purple, in spring.
The season is of no importance, astilbe can be planted in spring or in fall, but what it needs is acidic soil such as heath soil.
- Select a spot that is preferably shaded over, especially during the hottest hours of the day.
- The soil must be acidic, quite cool and well drained.
- It is important to add heath soil.
- Astilbe loves rather rich soil, so in the best of worlds it would be fertilized before planting.
Propagation through rhizome division in spring or in fall, ideally every 3 years.
Astilbe in containers and garden boxes
The astilbe is the perfect plant to garnish your pot arrangements, containers and garden boxes. Since it is available in all hues ranging from pink to red, it truly embellishes arrangements with other flowers and keeps its beautiful foliage up to the first frost spells.
- Verify that the bottom of your pots have holes in them.
- Eventually, place a bit of gravel or clay pebbles at the bottom to increase drainage.
- Set each astilbe at least 12 to 16 inches (30 to 40 cm) from the next to give them space to grow.
Pruning and caring for astilbe
Remove wilted flowers regularly (deadheading).
Cut back the clump at the end of winter in order to promote sprouting of new leaves.
It is a good idea to water regularly in the year of planting and then again whenever the weather is hot and dry, because astilbe has an aversion to dry spells.
If in pots, a good counsel is to water regularly in summer to avoid having the plant desiccate.
