SEED HEADS

Based only on their wispy seed heads that float away in the slightest breeze, you might think that dandelions are a fragile flower — but that's not the case at all. Dandelions are particularly hardy and some can grow roots up to 15 feet deep in the ground. Their ability to self-pollinate and disperse seed heads multiple times per season contributes to their quick spread, as does the fluffy, umbrella-like structure of the seeds, which lets them travel long distances in windy conditions. And while they might be annoying when they're unwanted, dandelions serve an important role in the food chain by helping aerate soil so that it's more suitable for overall plant growth.
