Here's another way to earn acorns and build up the database. Chelle's adding photos of rose hips, buds, leaves, and canes, so if you've already added photos of all your roses, start adding their hips, buds, leaves, and canes. They all contribute to our knowledge of a plant.
When you add rose hips, please check the "fruit" option for the photo gallery. I know they could also be categorized as seeds and seed pods, but for the sake of uniformity, let's call them "fruit" the way Chelle has. That way, a search for rose fruit will bring up all of the photos of hips when our search engine gets really sophisticated and starts zeroing in on every detail.
You'll get an acorn for your first entry in each gallery for each plant. In other words, if you post photos of a 'Peace' bloom, the entire plant, the leaves, the canes, and the buds, you'll earn five acorns. If you post five photos of 'Peace' blooms, you'll earn only one acorn. Of course, you'll earn our undying appreciation for those extra four photos of 'Peace' blooms, but they won't add to your acorn stash.
