If you’ve ever received (or given) a dozen long-stemmed roses, chances are they were from a hybrid tea rose shrub. Hybrid tea roses have strong, sturdy stems supporting a large, well-formed bloom. Typically, the hybrid tea rose bloom is a single bloom atop a long, sturdy stem. Due to their long, sturdy stems with large, well-formed blooms, hybrid tea roses are sought after by florists worldwide.
