Value-for-money
'White New Dawn' is the white snow-flowered version of the excellent climbing rose 'New Dawn'. Its very doubled, slightly ruffled roses are also pleasantly fragrant, but in a less distinct way than those of its parent. Vigorous, very healthy and hardy, this rose adapts to all exposures and soils. It blooms from early summer until late autumn.

Description

The climbing rose 'White New Dawn' has managed to retain all the qualities of robustness and charm of its parent, the famous New Dawn, which is highly regarded by amateur and professional gardeners alike. Its double flowers with slightly blurred lines are a snowy white, and their beautiful fragrance recalls that of old roses. If the faded flowers are removed, they will be replaced in successive waves from May until autumn. With its strong vigour and undemanding nature, this rose will charm all lovers of romantic roses.

This 'White New Dawn' rose is the result of a cross between the roses 'New Dawn' and 'Lily Pons'. It carries the genes of the Wichura rose (synonym Rosa luciae), a vigorous botanical species native to East Asia. Just like the old roses 'Alberic Barbier' or 'Albertine', it produces very spiny arching branches, but it rarely exceeds a height of 3 to 4 metres (10 to 13 feet). Its small deciduous foliage is a bright medium green with a satin finish, and it falls in autumn. Depending on the growing conditions, it can be slightly susceptible to black spot (marsonia) and powdery mildew. 'White New Dawn' blooms abundantly in late spring and may rebloom to some extent in summer if it is not lacking water. The fall rebloom is regular, abundant, and prolonged if the faded flowers are pruned. Its flowers are cup-shaped doubles with a diameter of 8cm (3in), slightly crumpled, although the curved and turbinate forms of modern roses can already be seen on their fringed petals. Grouped in small bouquets, they consist of 20 to 39 white petals surrounding a barely pink heart adorned with yellow stamens, which are visible before the flower fades.

The climbing rose 'White New Dawn' will make a powerful and charming duo with its parent 'New Dawn', blooming for almost 6 months. This climber, which is undeterred by anything, dresses trellises, pergolas, or tall bushes wonderfully. It adapts to many situations, even flowering in the rather shady areas of the garden in our sunniest regions. It also accommodates all types of soil, but prefers well-tilled and deep soil as well as a well-ventilated exposure. Like 'Albertine', 'Felicia', 'American Pillar', and 'May Queen', it is particularly interesting for bringing lushness and colour to areas of the garden that are less favorable to roses. Sturdy, undemanding, and frugal, it will thrive in both the north and south of our country, with some care at planting. Like other large climbers, it can easily hide an unsightly structure, climb a wall, adorn a flowering hedge, or a sturdy small tree.

Obtained by Longley de Somerset Rose Nursery (Scotland), 1949.

Planting and care

Plant your 'White New Dawn' rose bush in a sunny or semi-shaded location, where its flowers will be protected from the strong rays of midday. Roses are tolerant but do not like excessive limestone. They will adapt to any garden as long as the soil is well worked and rich enough. If you notice stained or powdery mildew-infected leaves, remove them immediately. This rose bush may require a preventive treatment in spring with sulfur, which is very effective against fungal diseases. To plant your rose bush, work your soil by crumbling the earth and adding an amendment, such as dried blood or dehydrated horn, at the bottom of the planting hole. Water generously after planting to remove air pockets. Water regularly for a few weeks to facilitate rooting. Since 'White New Dawn' is a perpetual bloomer, it is necessary to regularly prune the faded flowers. This will promote the growth of new flower buds without exhausting the bush. Renew your rose bush by removing the oldest stems near the stump, then balance the bush by pruning short and long branches. Remove dead wood and ake space for ventilation in the centre of the bush. For pruning, choose an eye that points outward and make a diagonal cut just above it. Train your rose bushes as they grow to ensure they cover the support.

Care

Pruning instructions The new sturdy stems will be trained and the old ones removed if necessary. The 2-year-old branches are the most floriferous. It is helpful to reduce the stems that flowered the previous year to 3 or 4 buds, or pruned to 15 cm (6in). It may be useful to remove dead wood and remove faded flowers if fruit formation is not desired. Climbing roses can also be left to grow freely if there is ample space.
