Roses are beautiful, but almost every rose owner has gotten their skin pricked by a rose’s notorious thorns. Stories, songs, and poems all contain references to rose thorns, but modern rose breeders have worked hard to create a thornless rose called a Smooth Touch rose.
History of Smooth Touch Roses
The roses known as “Smooth Touch” roses are a very interesting group of hybrid tea and floribunda thornless to nearly thornless roses. They were developed by Mr. Harvey Davidson of California; a hobby rose grower and breeder that sought to breed hardier and more disease resistant varieties of roses. By accident, Mr. Davidson discovered the key to thornless roses. His first thornless rose was named Smooth Sailing. Smooth Sailing was a creamy apricot rose that loved to bloom and load up with blooms. Within this rose was contained the remarkable gene that inhibits thorn growth! Mr. Davidson then developed more thornless roses by outcrossing and inbreeding his roses.
Each year Mr. Davidson plants 3,000 to 4,000 rose seeds, and about 800 of those actually germinate. Mr. Davidson keeps around 50 of those that germinate that look like good roses. He then focuses on five to ten roses that have the unusual thornless and disease resistant traits. These varieties are given special attention and are considered the cream of the crop. These roses are then moved to the “graduate section” of his breeding program. The rose varieties that pass the quality control segment are sent to rose growers around the world for a testing period in various climates, and if they pass the various climate tests, are released commercially. This entire process can take five to six years to complete.
All of Mr. Davidson’s’ Smooth Touch® Thornless Roses are 95 to 100 percent thorn free. A few thorns may appear at the base of some of the canes; however, as the rose bush grows, the thornless gene kicks in and the remainder of the rose bush will then be thorn free. Smooth Touch roses are great for cutting and are wonderful repeat bloomers. They typically will need five to eight hours of good sun exposure for optimum performance but will tolerate less sun exposure with fewer blooms. Their foliage is a strong green, which enhances the blooms nicely. Smooth Touch roses are treated just like the rose bushes that have thorns; the only difference is that they are virtually thorn free.
