Can a morning glory flower grow faster or taller than a sunflower?

Morning glory flowers generally grow quickly, often reaching heights of 6 to 10 feet, but they are typically climbing vines rather than tall, upright plants. Sunflowers, on the other hand, can grow significantly taller, with some varieties reaching heights of over 12 feet. While morning glories may grow faster in terms of vine length, sunflowers usually surpass them in overall height. Thus, while morning glories can grow rapidly, sunflowers tend to be taller.
