Back Start Next Underground Package As summer nears, it is getting hotter and drier. How will you survive? First your flower dies back. There isn't much water available, so your roots dry up. Your outer skin gets tough. Without any water, your leaves can't make food, so they die back, too. But before they do, they send the rest of the food energy they made down to an underground bulb — and to new baby bulbs (bulblets). Now here you are: a little underground package ready to rest (go dormant) until you have what you need to grow. Good thing too, because winter is coming!
