the beginnings of a spring nature table

We've started our spring nature table: a yellow playsilk, a little glass jar of grape hyacinths from our garden, a couple of rabbits from Maia's animal collection, a nest with eggs (not real), and our basket of rocks and sculpey nature prints (time to make some more, btw). It's a work in progress. I'd like to bring in more real nature, rather than stand-ins such as the toy rabbits and nest, although I like those too. And I'm trying to think of other good ideas for a spring table. I'm thinking maybe growing a pot of grass or herbs (like here) and bringing in more flowers as well as any real egg fragments we find... I also love this fleece basket with pussy willow eggs. Any other ideas?
