Astilbe ‘White’, known in the garden as Astilbe ‘White’, combines white blooms with a size that is easy to place in a composition. Its foliage features shades of green, to be highlighted among different textures. The usual flowering period is June-July. Its dimensions of 51 cm by 45.5 cm reserve a place for it in partial shade beds and woodland gardens, without forgetting the space for its neighbors.
To plant Astilbe ‘White’, look for the following exposure: bright shade and suitable soil (kept moist, Clay). For Astilbe ‘White’, regularly check the soil around the root ball: it must remain moist. Water at the base when the surface begins to dry and adjust the amount of water based on rainfall; this exposure (bright shade) does not eliminate the need for water. A margin corresponding to its spread of 45.5 cm avoids having to move the clump in the first few seasons. The indicated hardiness zone is zone 4, to be assessed according to your garden's conditions.
The care of Astilbe ‘White’ primarily relies on observing the clump: monitor watering during heatwaves and remove old stems when the clump regrows in spring. Drying out of the root ball shortens the flowering of astilbes and can cause the edges of the leaves to brown. For plant pairings, consider lungworts, hostas, and tiarellas in varieties with similar needs. By composing around its size of 51 cm by 45.5 cm, you will preserve the visibility of its blooms (June-July) and allow circulation between plants.
