Astilbe ‘Glut’, known in the garden as Astilbe ‘Glut’, combines red-toned flowers with a volume that is easy to place in a composition. The foliage has green hues, to be highlighted among different textures. The usual flowering period is in July-August. Its size of 70 cm by 50 cm reserves it a place in the middle of a flower bed and for group plantings, without forgetting the space for its neighbours.
In terms of cultivation, Astilbe ‘Glut’ appreciates sun to partial shade exposure; the recommended soil should be kept moist, Clayey. For Astilbe ‘Glut’, regularly check the soil around the root ball: it must remain fresh. Water at the base when the surface begins to dry and adjust the amount of water according to the rain; this exposure (sun to partial shade) does not eliminate the need for water. A spacing of about 50 cm between the centers is a starting point, to be adjusted according to observed vigour. The indicated hardiness level is zone 3, to be assessed according to the conditions of your garden.
When planting Astilbe ‘Glut’, monitor watering during hot weather 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 associations, consider perennial geraniums, echinaceas, and campanulas in varieties with similar needs. The flowering (July-August) and spread of 50 cm will serve as markers for distributing other plants around this plant.
