The silhouette of Astilbe 'Ruby Red' (Astilbe 'Ruby Red') adds relief to garden compositions. Among its distinctive details: fragrant flowers. The foliage features shades of green, to be highlighted among different textures. The usual flowering period is June-July. Its size of 40 cm by 45 cm reserves a place for it in the middle of flowerbeds and in group plantings, without forgetting the space for its neighbors.
The success of Astilbe 'Ruby Red' begins with its location: sun to partial shade, in suitable soil (kept moist, Clayey). For Astilbe 'Ruby Red', regularly check the soil around the root ball: it must remain fresh. Water at the base when the surface begins to dry out and adjust the water supply according to rainfall; this exposure (sun to partial shade) does not eliminate water requirements. A spacing of approximately 45 cm between centers is a starting point, to be adjusted according to observed vigor. The indicated hardiness level is zone 3, to be assessed according to the conditions of your garden.
Throughout the seasons, Astilbe 'Ruby Red' benefits from timely care: monitor watering during hot weather and remove old stems when the clump regrows in spring. The drying out of the root ball shortens the flowering of astilbes and can cause the edges of the leaves to turn brown. For pairings, consider campanulas, perennial geraniums, and daylilies in varieties with similar needs. The flowering (June-July) and the spread of 45 cm will serve as benchmarks for distributing other plants around this plant.
