Astilbe is a genus of 18 species of rhizomatous flowering plants, belonging to the family Saxifragaceae, native to mountain ravines and woodland in Asia and North America.

They are widely adapted to shade and water-logged conditions, hence they are particularly associated with pond-side planting.

They also tolerate clay soils well. Numerous hybrid cultivars have been raised. In addition, different varieties bloom at different times and are available in varying heights.

Astilbe flowers may be a few inches to a few feet in height, depending on the astilbe plant you choose. If you do your research, you’ll be rewarded with their spiky blossoms (in an array of heights) all summer long.

Having and using the right astilbe plant information can mean the difference between a large, fully developed bloom and one that is stunted or displays leaf browning and dieback.

Astilbe plants flourish with the right soil, food and location.

While maintenance of the plant is minimal, care for astilbe includes regular, even watering throughout its active growth, especially if planted in areas with more sun.

Drying out can lead to leaf scorch, drying leaf margins and can even be the death of the astilbe plant.

The right astilbe growing conditions and fertilizer result in large feathery plumes. Occasionally amending the soil with compost or fertilizing with an organic product or fertilizer high in phosphorus is also recommended.

Spent plumes can be cut back in spring or left alone for winter interest. They can also be divided about every four years as needed.

A benefit of growing Astible  is that they are fully hardy and perennial, which means they do come back reliably each year to provide colour in the garden and are good value for money.

If your Astilble is looking less good, not flowering as well and it has been established for a few years, it is best to divide it which should improve it.
