Explorer Series: Red Roses

Explorer series-John-CabotThe Explorer roses were developed at the agriculture research station in Ottawa, Ontario and l’Assumption, Quebec to withstand the cold Canadian winters. Using Rosa rugosa, R. kordesii, Hybrid Teas, and Floribundas breeders produced roses that had the hardiness and disease resistance of old roses with the beauty and repeat blooming of modern roses. The resulting series consists of about twenty two cultivars named to honor Canadian explorers and includes red, pink, white, and a few yellow flowered plants as well as low growing groundcover, upright shrub, and climbing roses.
