Thousands of green thumbs are digging in at the Washington National Cathedral's 74th annual flower mart this weekend.
It got underway Friday and continues Saturday from 10 a.m. to 6 p.m. The Cathedral is bracing for a crowd of nearly 10,000.
Green thumbs of all ages can explore flowers of all sizes and colors. There's also food, entertainment and several vendors.
In years past, organizers have raised a quarter million dollars from the event, which is used to maintain the 59-acres surrounding the cathedral.Cathedral officials say money raised will not go toward earthquake-related repairs.
But they've been urging supporters to vote online, to help them win a $100,000 Partners in Preservation grant.
"We'll be working the crowds and handing out flyers, asking them to vote and to bring them inside," says Washington National Cathedral spokesman Richard Weinberg. "Although this weekend is about flower mart and being outside, I think it's a testament to the folks that show up that they want to preserve the beauty of the Cathedral inside as well."
