Easter is behind us.
Suffering from a sugar hangover, I download my weekend pics and reflect on soft plants and horses instead of sticky peeps.
Lupine is emerging. Horses look forlorn as they shed their winter coats.
|Lupinus perennis is waking up. Check out the hairs on the leaves.|
|Ringo is forlorn, but happy. Even with a messy mane.|
As I research pubescent leaves, I think about how lupine uses those downy hairs or trichomes to protect itself against moisture loss to the elements. Hairs that create a boundary layer between the delicate leaf surface and drying April wind. Hairs that reflect the damaging rays of a July sun.
Furry leaves are one of the many adaptations that keep this native prairie plant healthy during a Wisconsin growing season.
What about that water droplet in the center? Is there a function associated with this entrapment? Does it create a lens effect which magnifies the sunlight, warms up the center and enhances photosynthesis during a cool spring morning? Or maybe the plant absorbs the droplet slowly before the sun has a chance to evaporate it away.
So many questions.
Do you know?
