"Included in this encyclopedic work are not only every Rose known to be obtainable commercially anywhere in the world today but many of the important varieties of bygone days, and a list of all known species Roses..."
-J. Horace McFarland
The offices of The American Rose Society serve as International Cultivar Registration Authority - Roses (ICRA) by appointment of the International Society for Horticultural Sciences.
Modern Roses was originally published in 1930 with 2,511 collected rose registrations world-wide, Today, the American Rose Society's Modern Rose database is home to more than 37,000 registered roses.
Access to Modern Roses database is available to everyone through an annual subscription and is membership benefit available to all American Rose Society Members.
Cultivars registering roses will need to request authorization from the registration committee, but do not need to be members or subscribers to be approved.
This will also be the 93rd time Roses in Review will be conducted in which rose growers everywhere can review new roses they've grown in their own garden. Roses included in the survey have generally been on the market one to four years and are available commercially, although some on a limited basis.
