A smaller proportion of their crowns are winter-injured and these cultivars can easily regrow to their mature heights the following growing season. Snowcover affects rose size and habit in two ways. It is a natural insulator of rose canes, serving to minimize dieback from low winter temperatures. A heavy snow can also weigh canes down, resulting in a wider, flatter plant habit the following growing season. Descriptors for Growth Habits of Rose Cultivars arching . . .
Growth is similar to the spreading form but cane tips bend back towards the ground.
These cultivars produce long canes that, when tied or supported, will climb indefinitely. If not supported, these plants take on a wide arching habit. Many upright canes create an erect dense plant habit. Canes grow horizontally over the ground s surface. Upright canes create an erect plant similar to the dense form, except that the number of canes is fewer, resulting is an open, airier habit.
