How do perennials spread?

How do perennials spread?

• A. Seeds, rhizomes, stolons, tubers, bulbs.
• B. Leaves and stems only.
• C. Only by seed.
• D. Only by wind.

Answer: (A)

Perennials have multiple ways to spread, using both sexual reproduction and vegetative growth. They can produce seeds to establish new plants, but they also spread through vegetative structures that persist from year to year: rhizomes (underground stems that send up new shoots), stolons (above-ground runners that form new plants at their tips), tubers (storage organs that can sprout new plants), and bulbs (storage organs with new shoots). Because all of these pathways contribute to how a perennial colony expands, the most complete and accurate description is that they spread by seeds as well as these vegetative structures. The other options miss key methods—leaves and stems alone don’t reliably produce new plants, and spreading only by seed or only by wind ignores the common vegetative propagation that many perennials rely on.
