GUIDE TO CEDAR CREEK

Discovering Wildflowers

The Cedar Creek valley, part of Indiana’s Central Till Plain Natural Region, has good growing conditions for wild plants: glaciated terrain with generally forested vegetation, often poor drainage (clay soils intermixed with gravels from moraine deposits), temperatures from -20F to 90F, yearly moisture averaging 38.3 inches.

The Cedar Creek region is now considered to be in USDA Hardiness Zones 6a and 6b. The minimum temperature is now higher than mid 20th century minimum temperatures. As a result, we can expect warmer weather plants from further south to survive winters in the Cedar Creek area. As the climate changes and temperatures warm, some native plants we now see only occasionally may become more common, and seasons will be extended: earlier spring and later fall. While suggested blooming times will be relatively similar, we can expect to see different flowers, even different weather and rain patterns.

When we can identify and name specific wildflowers to look for in each season, we are more likely to find, enjoy, and protect them. So have fun learning both English and (sometimes quirky-sounding) Latin names as you identify these wildflowers in the diverse woods and meadows of the Cedar Creek valley. Children also like learning these names (and may find the wildflowers faster than you can). Be sure to explain why wildflowers must not be picked.
