Why does bindweed grow so high on a rose bush?

Bindweed grows high on a rose bush because it is a climbing plant that seeks sunlight for photosynthesis. It uses its twining stems to wrap around other plants, taking advantage of their height to access more light in crowded environments. Additionally, the rose bush provides a supportive structure for bindweed, allowing it to thrive and spread rapidly. This competitive growth can hinder the rose bush's access to sunlight and nutrients.
