Fabulous plant. My three White Lady asters have grown significantly despite the summer heatwave, reaching almost 110 cm (43in) (more than announced). The flowering lasted over a month, from September to mid-October. Today, I can still see new buds appearing. Only one regret... I really should have planted them at the back of the border as described because they take up a lot of space in my border!

Of beautiful stature and very floriferous, it produces a profusion of pure white, semi-double flowers, with a golden yellow centre. Bridging the gap between summer blooms and autumn colours, this tall perennial appreciates moist soil at the back of flower beds. It spreads slightly over the years. Excellent cut flower.

Description

Aster novi-belgii 'White Ladies' is one of the best white-flowering autumn asters. This plant, with its exceptional floribundity, produces a myriad of small semi-double daisies with golden hearts in late summer, so numerous that they cover its compact and luxuriant vegetation and transform it into a giant bouquet. Preferring moist soils, this spreading variety is ideal for elegantly occupying the back of flowerbeds, where it will spread without bothering its neighbours. Its flowers are splendid in autumn bouquets.

 

 

Aster novi-belgii belongs to the asteraceae family, it is a hardy perennial native to temperate and cool regions of North America. 'White Ladies' is a horticultural selection that has a compact and bushy, upright habit. It will reach a height of 80 cm (32in) when in flower and will rapidly spread to 50 cm (20in). The exceptionally generous flowering occurs in September and October. The flowers are grouped in large 5 cm (2in) heads; the outer edge is made up of a double row of pure white petals and in the centre, the tubular flowers form a golden yellow heart. This aster is deciduous. The smooth and branching stems bear dense foliage, composed of slender, elongated, pointed, dark green and glossy leaves which can be susceptible to mildew.

 

Asters are essential in English-style gardens, cottage gardens, or naturalistic borders. They are undemanding and blend very well with all other plants such as grasses, Salvia microphylla, Croscomia 'Meteore', Dahlias, and perennial daylilies. These cheerful perennials accompany the splendour of autumn foliage. The 'White Ladies' aster will never be more beautiful than when planted in large cloud-like masses, in the company of the tousled pale pink flowers of 'Fellowship' asters, the magenta daisies of 'Crimson Brocade', or Solidago sempervirens. Try combining asters with 'Grace' Cotinus or dwarf, winged Euonymus: the colour combination is surprising in autumn.

Planting and care

Plant 'White Ladies' Aster in autumn or spring in light, well-worked, moist, soil that is not too poor. You can add some organic matter if your soil is rocky. Heavy and wet soil will shorten its lifespan and it appreciates full sun. It is not necessary to stake the plant, but it will need a spot sheltered from strong winds, near a wall or a dense hedge. Once established, avoid moving your aster as it does not tolerate it well. In a flower bed, maintain a spacing of at least 80 cm (32in) between plants. Unfortunately, it is quite susceptible to powdery mildew, so plan preventative treatment and promptly remove any affected parts. Divide the clumps every three or four years to ensure continued flowering. Cut back the withered stems after flowering.
