We've reached that week when you can literally see spring come in day by day. In the park the green tips of the tulips and daffodills poked up out of the ground during the February thaw and then got all frostbitten and raggedy when the deep cold returned. Now they're an inch taller every morning, still torn and brown on top but coming up strong and green. One patch of gold, white and purple crocuses is blooming; the others are clearly on the way. A few daffodills have burst from the yellow pods that swell at the top of their stems. Yesterday the trees down by the white tent were still skeletal; today I could see a yellow-green haze on the branches. Nothing green has happened to the hill across the river yet, but a red-brown fuzz has replace the white outlines of one patch of trees. The most thrilling thing around here, though, is the cactus in the triangle garden. Every year it looks like it's just not going to make it back, and this was a particularly bad winter. But the leaves -- do you call them leaves, on a cactus? -- have started, just in the last two days, to lift and swell. They're taking up water now that they're convinced it won't freeze on their insides anymore. Soon the daily changes in the gardens and parks will be more subtle, but this week -- which happens to be the one at the end of which we turn the clocks and get our daylight evenings back! -- you can watch the seasons change.
