Growing on Sandy Tropical Beaches

Our world has more ocean than land, so there are vast coastlines. I live in the center of the second-largest continent, which puts me nearly as far from a coastline as is possible. So of course I'm enchanted by beaches.

Plants in Winter

trees in winter

When considering winter in Colorado, I often want to write that plants rest, but in fact, I don't think that is true. A rest is defined as a time to relax and recover strength. Plants drop their leaves and go dormant in winter because they cannot move ice in their tissues, let alone use it to grow. Furthermore, water expands as it freezes, so freezing rips up most cells. There is no recovery of strength in winter, only waiting out an impossible season.

That said, the plants that survive through the winter are an elite minority.
