A MAIDEN IS A ROSE THAT HAS BEEN NEWLY GRAFTED.
Unlike most grafted roses which are sold as #1 bushes, maidens are field grafted in summer, dug and shipped the same fall, a full year before most of the large growers harvest and ship their #1 grade roses.
A bare-root maiden plant
The advantages to growing maidens are as follows:
You receive a dormant bare-root plant of rose rootstock, with the bud of the variety you have selected grafted and healed on the trunk (or shank) of the rootstock.
