How do grasses grow without our sowing any seeds?

BRY2K

The seeds for grass come from grass flowers-they plump up at the base of the flowers as they mature. The flowers of lawn grass grow in a tassel that looks like a straggly sheaf of wheat. That's no surprise, since wheat is a type of grass itself. Lawn grass doesn't usually form seeds unless it grows more than a few inches high-so mowing the lawn makes grass flowers pretty scarce. If you let the grass grow, though, it starts looking downright "wheatie." http://findarticles.com/p/articles/mi_qa4136/is_200511/ai_n15743616 I think you'll find this informative (and amusing) one full year of grass growth in about one minute: http://www.watching-grass-grow.com/year/ Dec 19 08, 1:04 PM
