Isn't it interesting that so many of our showiest early bloomers are yellow? Winter aconite, witchhazel, daffodils, cornelian cherry, and now forsythia. Is this a biological phenomenon, or sociological?
In other words, does nature prefer yellow early bloomers — perhaps to attract a particular early pollinator, or pollinators — or is it we humans who prefer a bright, cheery yellow to shake off the winter blues, and we choose our plants accordingly?
Perhaps I'm imagining this color shift, but I think we are about to make a turn now to whites, pinks, and reds. Again, natural or human preference?
