Wordsworth Flowers, spring . . . there is something about the beginning of a new cycle of growth. It’s time for flowers to poke their dainty heads om beneath the earth, to open those tightly osed buds. Leaves, new growth are sure to follow. The certainty of nature provides calm and the promise of adventures to come. And so it is with horticultural activities — spring brings a new cycle of growth, new activities. If you’re looking for wisdom, for happiness, or for pure pleasure, you’re sure to find some- thing to do on the following pages. It is our pleasure to present this palette to you. John A.
