Last December was the warmest on record for Washington, the Washington State Climate Office reported, and the region has seen a mild winter so far. Many garden plants are already showing small buds in February, an early sign of growth that is drawing attention from both gardeners and scientists.
Takato Imaizumi, a professor of biology at the University of Washington, studies the genes that plants use to monitor seasonal change. His research focuses on the internal genetic mechanisms that allow plants to detect environmental signals and to time life-cycle events such as flowering.
Imaizumi has discussed how plants know when to bloom and whether warmer winters might alter that timing. The source material reports his role and the subject he addresses but does not include detailed findings or firm predictions. The situation highlights a broader question under discussion between climate observers and plant biologists about how milder winters could affect normal seasonal patterns.
