The moist roadside in many places is dotted with yellow touch-me-not flowers. They hang like earrings from their stems, and many call the plant “jewelweed” because of them. It is a pretty sight in the morning to see the bright jewels sparkling in the dew.
“Rubythroat” flashes about among them. “Rubythroat” is our northern humming bird. His throat is ruby red and sparkles in the sun. The rest of his body is green and brown. He shines like a jewel in the sunlight and darts from flower to flower. You cannot watch him, he flies so fast. But when he wishes a sip of honey he poises on his tiny wings before the jewelweed.
Into the dainty swinging flower he darts his slim black bill. He is partial to the honey of the touch-me-not, and wherever it grows in abundance you will be sure to see the rubythroats darting about.
Rubythroat does the flower a favor in return for the honey he gets.
You know about that. He carries pollen to it from some other flower. This new pollen enables strong seeds to form. The jewelweed is very careful to have strong seeds. It covers the pistil with a hood of its own anthers. Behind the anthers in a dark little room the pistil waits until all the pollen is gone and the anthers have fallen off.
The flower does not wish its pistil to receive its own pollen. The earth is crowded, and the seeds must be strong to grow. So the pistil is hidden behind the screen of the anthers until there is no more pollen left; then it comes forth and waits for the birds or the bees to bring it fresh pollen.
The anthers and pistil are not on the floor of the touch-me-not flower, as they are in the nasturtium. They hang from the roof like tiny chandeliers.
The bees do not walk over them, but touch them with their heads or backs, and the humming bird touches them with the top of its bill or with the feathers on its face.
When the birds or the bees have brought the pollen, the yellow corolla falls off and the fruit grows fast.
It is a smooth and delicate fruit, and it may be you know what it does to help the seeds find room.
