ROSES BHT231

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.

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.
