With their showy and fragrant flowers, roses are often used in North Carolina landscapes. Roses as cut flowers are appropriate for any occasion. Fraught with insect, mite, and fungal pests, the challenge of growing a nice-looking rosebush has been euphemistically described as "interesting." About 350,000 roses are handled by Southern nurserymen each year.
