Most roses actually grow well on their own roots, after all, that is how they were "found" as seedling in the breeding process. So, why then go through the trouble of grafting roses on a rootstock or, even crazier, spend 25 years developing a new one like we did? The answer is that there are many reasons why one would use rootstocks. 

The fact is that the "noble" rose will profit from the rootstock. Originally root stocks were selections from wild botanic roses like Rosa canina.  The invention of top grafting (Stenten) made it easy to use other types of hybrid roses like Natal Briar which became a huge success as a result of the invention of "Stenten".  In the 1980-ies a few rose rootstock programmes were started at, amongst others, the Wageningen University in the Netherlands. Many rootstocks were tried, new breeds were developed and introduced. The excellent Natal Briar comes from one of these programmes and was introduced by Dr. Peter van de Pol. Van de Pol has made it his goal to breed a better rootstock than Natal Briar which has become the leading world standard for many years now.

Our breeding programme originates from the programmes at Wageningen University. As a private company we have been breeding new rootstocks for the last 15 years in order to find the ultimate rootstock capable to replace Natal Briar by producing at least 10% more biomass. At this moment we have three distinctive root stock types available which produce 1) more shoots or 2) heavier stems or 3) more length. 

All types are being tested at major rose producers in several countries.  We are represented in Africa bij Stokman Rozen Kenya, in Europe bij Kordes Roses International and in North- and South America by Moerheim.
