Retirement Party Ideas

You don't mention your budget, but for someone with those interests, I would think a gift certificate to Orvis (they have a retail store in Dallas:

or
LLBean (www.llbean.com) or Plow&Hearth (www.plowheath.com).
With the latter being likely the best fit as they have more gardening paraphenalia than the others. But, they all offer higher end, high quality products that make great gifts. This, along with a basket of gardening accessories like gloves, Burt's Bee's gardeners gift set, etc. would likely be appreciated.

This is gonna sound weird .. but Go to Cabela's and Bass Pro Shop and just walk around and get ideas. Then go walk around Garden Ridge. Do a big gift basket with several smaller things in it and gift cards and a B&B to a log cabin or something.

Hi, Kristen!

I do personalized wine gifts. If she is a wine drinker, you could put a personal message, and even a photo, on a wine bottle. You can order a 2-bottle gift box, a bottle of wine and truffles or go in on a case of custom-labeled wine. Check it out at www.FineWinesAtHome.com

Good luck with the party! Sounds like you're putting a lot of thought into it and doing a great job!

My mother & mother in law both love gardening, so whenever I need to give a gift, I either get a gift certificate to a local nursery or some type of fancy gardening gear (kneeling pad, pretty gloves). I've even made a "gift basket" out of a big watering can and filled it with small garden tools, gloves, hat and seed packets. Good luck & have fun.
