Can you remember where you put your car keys? Recent work in the new system of study of plant signaling and memory shows that plants may have better memories than we do!
There are fascinating plants high in the Peruvian Andes that have this amazing skill set of “memory”. The Nasa poissoniana, is a vivid star-shaped flowering plant. Besides the beautiful blooms with their talented stamens, they are also known for the stinging hairs on each stem. Touching the stems is “really painful.”
One of their greatest talents of the Nasa poissoniana is that they can gymnastically wave around their stamens—organs used for fertilization—to maximize pollen distribution. Other plants curl their leaves or catapult their seeds—but this amazing plant just “does the twist” for maximum pollination!
Even more surprising, in a recent study in “Plant Signaling and Behavior”, it is suggested that individual plants can adjust the timing of these movements based on their previous experiences with insect pollinators. In other words—they learn from the past.
Over the course of a flower's life, individual stamens swing one by one into the flower's center. When a bee comes calling for nectar, it triggers the next stamen to come sweeping in, ready for a new bee—or maybe the same bee's return. In this way, the flowers maximize their chances of transferring pollen to many different flowers.
Perhaps the most important part of this observation and discovery is that it helps create a broader picture of what plants can sense and learn and do. Now, if we can only remember where we put those keys!

I am a member of a local Rose Society and this past weekend we had our annual rose show. I have been in this society for several years, and this is the first year I exhibited. (Don't ask me why.) There is general agreement that this rose show is the high point of being a member; one horn of the dilemma. It is, after all, the one time the members act as a group and there is a frenzy of activity surrounding the event. There is an amazing amount of scurrying around to arrange a venue and to move all of what it takes to actually show the roses. As an exhibiter, I had to cut the roses the night before the show and appear early on the morning of the show to prepare each bloom. Several times I asked myself if this kind of exhaustion was why I joined in the first place. And then there are the rules of just how to show the flowers – one flower per stem, arrangements, and bouquets, multiple flowers per stem. I believe there were 35 exhibition categories. It is less the amount of work involved that is tedious, but rather the plethora of rules surrounding the event that make it questionable.
The other horn, and thus the dilemma, is growing the roses. Actually, they are rather easy plants to grow. They are not the thirstiest plants, they want sun and a place that is relatively undisturbed so their nature can have full rein to do its thing. And they give back a lot in beauty and fragrance. However, on my own accord, I find myself having to do a lot for them: fertilizing, mulching, dead-heading, replacing the unproductive ones with new plants. Not to forget standing back and adoring them and getting close and smelling them.
So the best I can resolve my dilemma is to tell myself that there is no such thing as a free ride. With relatively little mental and physical effort, I can have both. And so, forward I go: growing and showing.

Long-time UC Cooperative Extension ag assistant Michael Yang broadcasts a weekly "Hmong Agriculture Radio Show," providing a crucial connection for immigrant farmers with ag information and services, reported Jessica Kutz in High Country News.
“His voice is really important,” said Ruth Dahlquist-Willard, UCCE advisor to small-scale farmers in Fresno and Tulare counties.
During his one-hour broadcast on KBIF radio, Yang plays traditional Hmong folk music, reads through market prices for Asian vegetables, provides timely farming advice, pesticide safety and labor information, and Occupational Safety and Health Administration updates. He started the program about 30 years ago.
“A lot of farmers said we need to be aware of what is going on,” he said. “So I talked to my boss and we were able to get some grants to help the radio announce agriculture (information) to the small farm community.”
The article said Yang first tried to connect with the Hmong community by going door-to-door, but farmers were distrustful of government meddling. With their radios turned to programming in their native language, farmers listen openly.
