Aster novae-angliae Rosanna

Aster novae-angliae Rosanna is a very tall perennial plant that thrives in moist soil, making it a majestic addition to any flowerbed. Its flowering season begins earlier than other New England asters. This upright variety is almost hidden beneath its countless deep pink-mauve flowers, which complement the colours of autumn. Aster novae-angliae is quite resistant to powdery mildew and thrives in humid climates and heavy, fertile clay soils, as well as wheat fields.

The family of asters, known as Asteraceae, is mainly characterised by the shape of its flower heads, which are called capitulum. Aster novae-angliae is native to the eastern and central regions of North America. This particular variety is particularly imposing, with its flowering stems often reaching heights of 1.40m (5ft) to 1.50m (5ft). It is very hardy, tolerating temperatures as low as -30°C (1°F), and blooms abundantly, although it often requires staking. 'Rosanna' transforms into clusters of small daisies of a rare pink-mauve colour, surrounding a small yellow centre that turns brown-pink. Flowering will be more generous if the plant doesn't dry out in summer. It prefers sun but will benefit from having its base protected by a thick mulch. The stems, woody at the base, bear narrow, velvety, dark green leaves.

The 'Rosanna' aster is perfect for adding late-season blooms to your garden, but you can also plant it in large pots to brighten up the surroundings of your home. In the ground, create a rustic feel around your asters with other tall perennials (Gauras, Rudbeckia, perennial sunflowers, inulas), small bushes (landscape roses, Perovskia, Caryopteris, small Hydrangea macrophylla), plus evergreens like cotoneaster, Lonicera nitida, and creeping junipers to provide some greenery alongside the asters until the end of their flowering season.
