Re: Sporting a rose

A "sport" is a genetic mutation, and therefore a permanent change in the
growth habits and/or flowering of the plant. Genetic mutations cannot be
induced by cultural changes - more or less watering, sunlight, fertilizer,
etc. Nor will merely moving a plant induce a "sport." However, *temporary*
changes in the color, form, and frequency of bloom are often caused by
weather & changes in sunlight. There are chemicals available that can cause
sporting, but they are powerful carcinogens, often caustic, and very
dangerous.
