What Are the Different Types of Roses?

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

Modern Garden Roses

  • Climbing types (Recurrent and Non Recurrent Flowering)
  • Climber (with stiff stems)
  • Miniature
  • Pillar
  • Rambler (with lax stems)

Non Climbing types (Recurrent and Non recurrent Flowering Types)

• Cluster Flowered bush (Floribunda)
• Grandiflora (an American term not widely used elsewhere)
• Miniature
• Large Flowered bush (Hybrid Tea)
• Recurrent flowering shrub (various sizes and forms)

  • Climbing
  • Climbing Tea
  • Noisette

• Multiflora
• Sempervirens (wild rose)

• Alba   tall and white
• Bourbon   flowers normally large, leaves glossy
• China   usually small, compact and twiggy growth
• Damask   open bushes/diverse group
• Gallica   very prickly
• Hybrid Perpetual   similar to modern roses but better leaf cover
• Portland
• Sweet Briar
• Tea   resulted from crosses with Rosa gigantea
