Dr. Solowey grew up in the San Joaquin Valley in California and studied horticulture, then turned away from commercial agriculture in disgust, coming here in 1971. "I don't come to organic agriculture from the hippie side, but as a frustrated agricultural scientist," she said.

"We've bred for yield and taste, but not hardiness, so we have a lot of plants as hardy as French poodles, so we have to spray to protect them, and then we pay the price," she said. "There isn't a cubic centimeter of water in the San Joaquin Valley that isn't polluted with something."

She planted the date seeds at the end of January after trying to draw them out of their deep dormancy. She first soaked the seeds in hot water to soften the coat, then in an acid rich in hormones, then in an enzymatic fertilizer made of seaweed and other nutrients.

"I've done other recalcitrant seeds," she said. "It wasn't a project with a high priority. I had no idea if the food in the seed was still good, but I put them in new pots in new potting soil and plugged them into drip irrigation and kind of forgot about them."

About six weeks later, she said, "I saw the earth cracked in a pot and much to my astonishment, one of these came up."

The first two leaves looked odd, she said, very flat and pale. "But the third looked like a date leaf with lines, and every one since has looked more and more normal -- like it had a hard time getting out of the seed."

Lotus seeds of about 1,200 years of age have been sprouted in China, and after the Nazis bombed London's Natural History Museum in World War II and a lot of water was used to put out the fire, seeds of 500 years of age also germinated.
