By now, everyone knows that MassHort members will be going to the Boston Flower & Garden Show for free. But there's a catch. It's pretty small as catches go, but if you've put off joining or renewing your membership, you have fewer than 45 days to take action.

That's because the cutoff date for free tickets (one for individual members, two for family memberships) is March 17th. You can't join the week of the flower show and expect those tickets. So, why not do it now?

Of course, there are plenty of reasons to join MassHort besides flower show tickets. Topping the list is the knowledge that you're supporting the oldest society of its kind in the country and you're helping to further an educational mission that reaches into schools and communities around Massachusetts.

But the tangible benefits are quite nice, too. You get a $25 gift certificate to White Flower Farm, one of the premier sources for premium plants in the country. You get complimentary subscriptions to Organic Gardening and Garden Design magazines. There are discounts at nurseries and reciprocal admissions to gardens and arboreta around the country. You'll also receive discounts on activities at Elm Bank, including classes and special events.

So, why wait? Use this link to renew or rejoin.
