Roses have been cultivated since as early as 2000 years BC.  Modern roses have largely originated as hybrids of the species roses which have been grown for centuries.

The exact origins of many of our modern roses is either complicated and difficult to follow; or in some cases difficult to track down at all.

  • Until 1975 the popular modern rose with the conical type flower was referred to as a Hybrid Tea. 
  • Hybrid teas are now called Large Flowered Roses by the experts.
  • Floribundas (until 1975) were roses which were produced as a hybrid between miniature roses (ie. True polyanthas) with larger flowering roses.  Floribundas are now called Cluster Flowered Roses by the experts.  'Hybrid Tea' and 'Floribunda' are still commonly used terms though.


Rose Growing Tips

There are over 100 species and thousands of varieties, grown as a bush, cut flower, a standard or espalier. They are often used as a feature against a backdrop of larger green shrubs; or behind a hedge of lower shrubs.

A beautiful bed of roses can be a gardener's pride and joy. Roses are generally very healthy plants and they live a long time if their health is maintained. Always buy healthy plants and choose a full sun site with well drained position to plant them in. As they have a shallow fibrous root system, avoid planting near large trees which have shallow spreading roots.

Roses are mainly deciduous, but occasionally evergreen, shrubs and ramblers. In warm zones like tropics and subtropics, roses tend to stay evergreen. The leaves usually odd pinnate & alternate. Stems are often very thorny. Flowers of most cultivars are large, colourful, and may be borne singularly or in clusters.

They are best in temperate climates; excessive heat and humidity will cause fungal problems.

In very cold snow prone areas; plants can be damaged over winter; but they will withstand some frost and even snow. Roses adapt to most soils, if drained, and can do well in clay soils where some other plants are difficult.

Providing good soil conditions will help ensure your roses stay healthy. Most roses will tolerate a wide variety of soil types, but prefer reasonable drainage. Adding gypsum to clay soils will help improve soil structure. Adding well rotted organic matter to the soil will help retain moisture, improve soil structure and nutrition, and help maintain soil temperatures at suitable levels for growth. If your soil has an acid pH adding lime will generally prove beneficial. The lime can be added to the soil prior to planting, or sprinkled onto the soil surface for establishing roses.

Roses respond well to feeding. A slow release complete fertiliser or well rotted manure is best.

Roots can be burnt if they come in contact with strong fertilisers.

Be careful to keep rotting material away from the base of the rose to prevent any possible disease infection.

Watering is essential if a rose is to flower well. Avoid watering the foliage - it's better to make a dish in the soil surface at the base of a plant and fill it with water to allow slow penetration. Don't let plants dry out.

Annual winter pruning is essential to rejuvenate the plant and encourage growth of young wood (flowers form on these young shoots...the more young shoots, the more flowers). In temperate climates at least half of the top growth is removed each winter. In snow areas cut plants back very hard (ie 95%) and cover with straw over winter. Roses are usually budded (grafted) so when you prune them do not cut below the bud. Plants pruned regularly can last more than 100 years.

Roses are largely sold bare rooted in winter. You will buy the best selection of plants early winter when they are first released onto the market. Roses sold at other times of the year are in pots and can be planted at any time.

Aphis and caterpillars are major problems. They can be controlled with insecticides such as pyrethrum. Black spot, mildew and rust are common fungal problems and should be controlled with a good fungicidal spray.

To minimise pest and disease problems always remove and burn fallen leaves, prunings and mildew infected shoot tips. Ensure that plants won't be overcrowded. Good ventilation around your roses helps prevent fungal infections occurring.

HOW CAN ROSES BE USED?

  • As a Garden Plant
  • For Scent -  Parts of a rose are scented- used for perfumes, oils, rose water for cooking, petals flavouring for cakes, desserts, drinks and as a colourful garnish/ decoration.
  • Cut Flower Production
  • An Edible Plant -    Parts of a rose are edible- rose hips are used in jams, jellies and as a rich course of vitamin C.
  • Medicinal Plant -   Parts of a rose have medicinal properties-rose oil for skin complaints, source of vitamin C, relaxing calmative oil for infusions and massage.

How to use Roses in the Landscape

The most wonderful thing about roses is that they flower heavily; and for long periods, some flower heavily only in spring, others can flower almost all year round.

This makes them most useful for adding colour to a garden. Like most plants, roses look best when massed (ie. the more you plant together, the better they look). If you want the best effect from roses, think carefully about the colours you use.

  • Consider the background to where the roses will be planted. If the backdrop is a dark wall or dark foliage; you need light coloured flowers for optimum contrast. If the backdrop is a white wall, there is not much point planting white flowering roses.
  • Consider also the contrasts of colours close to each other and how vibrant warm colours make an are appear warmer and cosier, cooler colours give a softer, more delicate, more spacious appearance ‘en masse’.
