Wow, what a perfect topic for this pollen palooza spring! And for the flower communion.
(Pollen and nectar are like the sacraments!)
- Wind Pollination is the oldest and most obvious.
Oaks, hickories, grasses, willow, pines. The bulk of our entire ecosystem here in the Shenandoah Valley! So much pollen just taking a chance that it might land on the right kind of dangly flower racemes so that an acorn or hickory nut can develop. It has to be the perfect shape, size and chemistry to work. And the rest just ends up on our cars, or in our noses and eyes!
Climate change has boosted pollen production. Since the 1990’s there is 21% more pollen, and the N American pollen season begins 20 days earlier. (Yale Climate Connections)
Pause here for Kleenex break!
All that wasted energy! But wait, is it really wasted? No. Nothing in nature is. Pollen is really rich in vitamins, minerals and protein ( up to 61% protein, when a steak is ~27%).. It has been called the “Only perfectly complete food”, which also has anti-inflammatory, antiseptic properties.
(National Institutes of Health) Pollen is actually eaten by humans and livestock as a dietary and therapeutic supplement.
So pollen is nourishment on the wind, All those tiny little packages of protein literally feed the little critters that make everything grow. It is hope for the future.
There’s a UU nature metaphor in here somewhere. Let’s think of everyday greetings and smiles as pollen – tiny in themselves, and scattered liberally around. A few grains may land in the perfect spot, but we may never know about it.
Just like pollen, our passing smiles can be hopeful food for the world. But hopefully not allergy producing!
2. First Flowers: the Magnolia Family
Ancient cycads were the trees that were around during dinosaur times. Sort of like big ferns. They had different cones with pollen and eggs and seeds. Something like ancient beetles came to eat that pollen, and carried it around from plant to plant.
But 100 million years ago, some ancient grandplant had an idea to put everything together on the same plant in the same structure. And maybe decorate it a little with “tepals.” To attract those beetles. (There were no bees yet) A flower!
All our current flowers descended from that common ancestor.
This ancient magnolia still has a cone, has giant pollen grains, can make a lovely inviting fragrance, even turns its leaves back to show their bright wide blossoms. Even heats up the blossoms as much as 5 degrees above the air temperature. It folds back up at night to trap the beetles, so they leave with fresh pollen for a new plant when they get out in the morning! How hospitable can you be! (Sara Stein, The Evolution Book)
Just like HUU: warm, cozy, nice smells coming from the kitchen, with big potluck dishes full of pollen. Flowers kept evolving, and so did insects, but the first flowers – magnolias are still with us.
(Introduce our own pollinators, Lorraine the butterfly and her friend butterfly. She swoops in to get the nectar, (wax bottles of sugar water),and leaves with pollen (cheese doodles) on her fuzzy glove body. They buzz several red fake flowers loaded with this nectar and pollen, getting cheese crumbs on their gloves in between.)
OK, the bees – and today, let’s talk bumblebees. They are furry, insulated, so they can come out earlier in the morning, and in the spring., native, 45 different species in North America. Only the queen survives the winter, and when she wakes up in the spring, she has to find a nest (often an old mouse hole in the ground), lay the eggs, and go find the babies some food. Sometimes only 50, The mama queen actually sits on her babies and warms them up when it’s too cold. (Instead, they make little balls of pollen for each egg they lay, and put into a little chamber for them. I once found a lovely nest inside a rolledup rug, and saw miniature bumblebee babies – which gave new life to the old children’s song: “Bringing home a baby bumblebee.”
Bumblebees can solve mazes, and learn to solve puzzles by watching other bumblebees. Like pulling a string to take a cap off a nectar containers. They can see ultraviolet, probably recognize human faces, and may even dream while they are asleep. All with a brain the size of a poppyseed.
Only the females can sting, and it’s hard to provoke them to. They will raise a leg to warn you they might sting if you push them too hard.
Bumblebees are “buzz pollinators”. They will bite a hole in the flower, grab onto the underside and shake it up to 400 x/second to make a cloud of pollen fall out. They are the main pollinators of tomatoes, blueberries, melons, eggplants. They are fuzzy all over, but some also have saddlebags to store pollen, and others have a special brushy spot on their tummies.
Commercially there are even companies that take boxes of bumblebees to greenhouses of tomatoes to pollinate them. (The Xerces Society, Journal – Nature)
Now we need a Unitarian metaphor. Hmmmmm, (Asked the congregation for their ideas):
“Don’t sting unless it’s really necessary”?
“Develop Hive mentality.”?
“Don’t harvest more than you need or can store.”?
“Get up early and work hard”.?
Conclusion:
So, Pollen is nutritious hope for the future, spread around liberally!. HUU is as welcoming as the first magnolia flower, with pollen and warmth for all us beetles, and it turns out that bumblebees are pretty good role models for us humans.
