Grades 3 - 5. Some signs of spring happen so quickly they might be missed if you are not paying attention. Observe the life cycle changes of the plants around the arboretum and see how the spring wildflowers compete with the trees for spring sunshine. Plant a fast life annual and a steady growth perennial to take home and, with detailed instructions, compare their life cycles.
