IN HONOR OF TU B'SHEVAT, COMING THIS WEEKEND: The Disappearance and Return of the Date Palm (Jo Ann Gardner, The Forward). An interesting historical review. But it is short of specific literary references. Naturally, Methuselah receives a mention.
And there's also this, from the same author in The Forward: Why We Eat the 7 Fruits on Tu B’Shvat. The short answer is Deuteronomy 8:7-8.
UPDATE: Missing title now included. Sorry about that!
