Astrantia major 'Sunningdale Variegated'

TheAstrantia major ‘Sunningdale Variegated’ is one of the most interesting white Astrantias. Indeed, while most Astrantias have green leaves, this variety features variegated foliage! In spring, the edges of its lobed leaves turn yellow and cream, gradually fading as summer arrives. Note that the more light this Astrantia receives, the more pronounced the variegation will be. However, if your soil tends to dry out in summer, we recommend placing it in partial shade with cool soil. Another remarkable feature of this Astrantia is its summer flowering: its 3 cm diameter umbel inflorescences comprise a star-shaped white bract, topped with numerous delicate pink flowers. This sweet mix of colours gives a very refined look to this Great Astrantia. During flowering, this hardy perennial (down to -15°C) forms an upright clump of floral stems reaching 40 cm in height, with a stump approximately 35 cm wide. Like other Astrantias, its foliage is deciduous. In a border, highlight the graceful flowers of Astrantia major ‘Sunningdale Variegated’ by pairing it with the mauve flowers of Penstemon digitalis ‘Pocahontas’, the white umbel flowers of Cenolophium denudatum, and the large Horse Chestnut-leaved Rodgersia.

Astrantia major 'Princesse Sturdza'

Simple and robust, these are the two words that characterise theAstrantia major ‘Princesse Sturdza’. This Masterwort stands out from its relatives by its large flowers with particularly long bracts. The inflorescences of this variety can indeed reach 5 cm in diameter! This Great Masterwort produces umbels with a collar of bracts that are white with green tips. In the centre, the cluster of white flowers reveals hints of mauve throughout the summer, from June to August and sometimes even until September. The clump of deciduous, palmate leaves forms a loose bush about fifty centimetres tall, dominated by rigid flower stems measuring 50 cm high. This ‘Princesse Sturdza’ Masterwort has very good cold resistance (down to -15°C). Plant it in a bucolic-style border with Campanula ‘Wedding Bells’ with bell-shaped flowers, hardy geranium ‘Mavis Simpson’, the Achilleas ‘Alabaster’ and ‘White Beauty’, the bright Shasta Daisy ‘Sonnenschein’, and finally with some grasses at the back of the border such as Deschampsia.

Astrantia major 'Star of Billion'

The Astrantia major ‘Star of Billion’ is the tallest cultivar in our collection of white-flowered Astrantias, reaching heights of up to 70, or even 90 cm. Despite its height, this vigorous perennial does not require staking due to its sturdy flower stems. The main advantage of this Astrantia is its abundant flowering from June to September. This variety, known for its floribundity, offers a profusion of flowers that start off pink, then turn greenish-white, and finally pure white at the end of the season. The white bracts are strongly veined and tinged with green at their tips. Its dark green, finely cut foliage contrasts perfectly with the inflorescences. The ‘Star of Billion’ Astrantia makes an excellent cut flower for summer bouquet arrangements and has excellent vase life. Hardy down to -15°C, feel free to plant the Astrantia major ‘Star of Billion’ in a naturalistic garden in partial shade alongside Lychnis viscaria ‘Plena’ with its candy-pink inflorescences, large-leaved Veronica ‘Charlotte’, Primula secundiflora with its pendulous flowers, and ‘Splendide’ Meadow Rue in the background.

Astantia major 'Alba'

Unlike the previously mentioned Astrantias, the flowers of the Astrantia major ‘Alba’ do not change colour over time. From June to September, its pom-pom inflorescences remain white. Only the large bracts crowning the tiny flowers are tinged with dark green at their tips. The needle-like flowers are certainly not very large (3 cm), but they are highly appreciated by bees, bumblebees, and hoverflies. Very chic, yet perfectly hardy, Astrantia ‘Alba’ brings brightness to shaded areas. This deciduous perennial with medium green deeply lobed leaves finds its place in a romantic garden alongside perennial plants in soft colours such as Meadowsweet ‘Elegans’, the Roses ‘Bonica’ and ‘Gruss An Aachen’, next to summer bulbs like Lilies, as well as shrubs like Ceanothus pallidus ‘Marie Simon’, Deutzia hybrid ‘Mont Rose’, or even Hydrangeas.

Astrantia major 'White Giant'

Very similar to Astrantia major ‘Alba’, the Astrantia major ‘White Giant’ is particularly distinguished from its cousin by its large flowers. Indeed, unlike the ‘Alba’ variety, it produces large inflorescences measuring 5 to 7 cm in diameter! This explains the name of this recent variety ‘White Giant’. This perennial with white flowers and bracts subtly tinged with light green is very floriferous. It ensures a significant production of flowers from June to September, often used for dried flower arrangements. Cold-resistant down to -15°C, it lasts for many years. The Astrantia major ‘White Giant’ with dark green foliage does not exceed 60 cm in height and 50 cm in width, and integrates beautifully into a white garden alongside Daylily ‘Arctic Snow’, Heuchera ‘Green Spice’ with silver-reflecting foliage, Polemonium caeruleum ‘Album’, white Epilobium, and finally a Clematis with white flowering climbing its support.
