are dormant throughout winter. Planting is possible, so long as ground is not waterlogged or frozen.
collectors have always prized any variety which is different, whether in shape, colour, scent or size. There is plenty of choice to inspire keen rose-growers.
Red, yellow and white are familiar rose colours but more exotic shades are available.
The green rose
Besides ‘Viridiflora’, there is a lovely miniature, ‘Green Diamond’, with greenish pompon. The variety ‘Peppermint Ice’ has clear green .
Black and blue
Black always excites the gardener’s imagination. Many very dark red roses claim to be the blackest. Grow them where the sun cannot burn the petals. ‘Deep Secret’, a Hybrid Tea, is a fine choice for its depth of crimson.
True blue does not exist in roses, despite some names, but there are a host of lavender-to-purple types.
‘Shocking Blue’ is a popu¬lar cluster-flowered rose.
Several ramblers areand give clouds of lavender and purple blooms. ‘Amethyst’, ‘Violetta’ and ‘Veilchenblau’ are the best.
If you want a thorn-less rose, try ‘Zephirine Drouhin’, one of the most popular climbers. It grows anywhere and produces masses of bright pink, heavily scented flowers in summer and autumn. Its relative, ‘Kathleen Harrop’, is very pale pink and equally thornless.
There are old and modern striped varieties.
‘Stars and Stripes’ is red with white stripes. It is an easy-to-grow miniature.
‘Harry Wheatcroft’ is a Hybrid Tea with orange and yellow stripes.
Little and large
Roses vary hugely in size. A rose in California, R. banksiae alba-plena, is said to cover 2000sq m of trellis. In England a rambler ‘Kiftsgate’ is over 30m wide. R. longicuspis, one of many fast-growers, makes 6m of growth in a season.
Miniatures are good to grow in. Try:
‘Starina’ (25cm), vermilion.
‘Magic Carrousel’ (40cm), red and white.
‘Pour Toi’ (20cm), cream.
