Number one roses move over, jumbo roses are here. A jumbo rose is simply a dormant root stock that is graded well above a premium number one rose and is usually discarded because they're large and hard to ship. Well, not anymore! At Spring Hill, we ship jumbo roses of all kinds allowing your favorite varieties the chance to bloom two or three times more the first year than number one graded roses. Grow a bigger, healthier, faster blooming rose bush with new jumbo roses.
