For a sun to partial shade composition, Iris 'Riveting' (Iris pumila 'Riveting') offers flowers in shades of white, blue, and purple. The foliage features shades of green, to be highlighted among different textures. The usual flowering period is June-July. The clump reaches approximately 40 cm in height and 25 cm in spread; use these dimensions to position the plant in the middle of a flowerbed and for group planting.
To plant Iris 'Riveting', look for the following exposure: sun to partial shade and suitable soil (well-drained, rather light; avoid water pockets around the crown). After planting Iris 'Riveting', water enough to thoroughly moisten the root ball. Once established, allow the surface to dry between waterings and prioritize drainage, especially during warm spells. A margin corresponding to its 25 cm spread avoids having to move the clump in the first few seasons. The indicated hardiness zone is 3, to be assessed according to your garden's conditions.
In an Iris 'Riveting' planting, cut back spent flower stalks after blooming and keep the green leaves to nourish the underground organs. The botanical group of the iris determines the planting depth and its water needs; bearded and Japanese irises are cultivated differently. For companion planting, consider border sages, catmints, and yarrows in varieties with similar needs. By composing around its volume of 40 cm by 25 cm, you will preserve the visibility of its bloom (June-July) and circulation between plants.
