Season Overview

Description

The genus of stonecrops (bot. Alyssum) belongs to the tribe Alysseae in the cruciferous family (Brassicaceae). The genus comprises around 110 species. It owes its German name to the preference of many of its representatives for stony habitats. The lush and perennially flowering plants are partly annual, partly biennial or perennial. They grow herbaceously, more rarely as small shrubs. As extremely flowering and undemanding plants, stonecrops have won the hearts of many garden owners. These pretty sun worshippers like to adorn themselves with yellow flowers, although they are rarely found in other flowering colors such as white and pink. They are considered traditional rockery perennials. Many species form attractive cushions that add color to the garden and attract bees and butterflies in droves from spring to autumn. The exuberant blooms seem to spill over the beds and many varieties exude a pleasant fragrance. Stonecrops cut a fine figure with their dense growth in containers or balcony boxes. Alyssum benefits from the fact that it does not need a lot of water to bloom profusely and thrive healthily. As a cheerful splash of color on the balcony railing, window sill or in hanging baskets, species that grow lower and horizontally are particularly suitable. They look as if they have been poured over the planter, which gives them natural charm and grace. The enormous brilliance of their flowers attracts everyone's attention and invites butterflies and other nectar-gathering insects to settle on them for a while. Some stonecrops have extremely decorative leaves that make them a beautiful sight during and after flowering. Not all species are sufficiently hardy in our latitudes. By self-seeding, they can be admired again in the garden the following year. Leaf Alyssum species have stalked or sessile simple leaves, which are often hairy. They are arranged in basal rosettes or alternately on the stems. Flower The inflorescences are typically dense, simple or branched racemes. The flowers are hermaphrodite and have a radially symmetrical structure (with rays of symmetry running through the longitudinal axis). They are four-petaled and have a double perianth. Stonecrops have four slightly elongated sepals, four petals and six stamens. There are one to a maximum of eight ovules per ovary. The flowers are often bright yellow; white, pink or purple-flowered species are less common. Fruit The fruits of stonecrops are stalked, flat little pods. The shape of the pods varies from species to species. The seeds lie in up to two rows and are round to egg-shaped. In some cases the seeds are winged. Growth The representatives of the genus Alyssum are herbs, more rarely semi-shrubs. They grow to a height of between eight centimetres and one meter and have a spindle-shaped, thin root. The plants are hairy and have upright or lying stems. They grow prostrate to bushy upright and form cushion-shaped cushions. Use Their brightly shining flowers make stonecrops popular ornamental plants. They are ideal for enlivening sunny, dry areas. Amateur gardeners like to plant them in tufts and combine them with other dry perennials. If you don't have a garden, you can make your balcony or windowsill bloom with these pretty little perennials. In spring, Alyssum species are important food plants for bees and bumblebees.
