Butterfly Garden - What's in bloom? August


You may have noticed Button Blazing Star (Liatris aspera) greeting you if you enter through the science wing. One of my all-time favorites and what a beauty! This was one of 40 or so natives donated to us last month by Oakton Community College's Ken Schaefer who manages their numerous native ecosystems and landscapes on campus. It matures to about 3' tall, prefers full sun but can tolerate some shade and blooms for a short 3 weeks, so catch a glimpse while you can!

Butterflies, hummingbirds, and bees love this flower. Monarchs, Painted Ladies, and Black Swallowtails frequently sip from it. It's also great in flower arrangements, fresh or dry as the flowers keep their purple color :)

You may have also noticed its close relative, Prairie Blazing Star, which has similar bright purple flowers that fill out over a long central stem but grows to 5' tall and usually require staking until the prairie plot fills to prop it up and probably limit its height. The clusters of twisting stems create unique towering flower sculptures in our garden.

Butterfly Garden - First Monarch Caterpillar of 2010!

He was there on Tuesday but then I lost him... but then he was found!! Twenty feet away on another species of milkweed plant. I've seen the Monarch Butterflies hanging around but their 26-34 day egg/caterpillar/pupal stages have eluded me for the last few years. This guy's probably ten days old, another four or so until he pupates - in the safety of class 202's former lizard cage. He's super sweet. :) After a 9-14 day pupation he'll be off to Texas, maybe Mexico? Quite a dumbfounding mystery how three to four generations share a 2,000 mile migration...


Below are pictures from the garden's first Monarch capture and release in 2008. One of my Environmental Science students noticed the chrysalis on the side of the building when we got back from a field trip. Realizing that it might not survive another few weeks at kicking height I brought it home for a safe transformation!

The Endless Benefits of a Native Butterfly Prairie Garden...



Alas, some method to and reasoning behind the madness... The Maine East Butterfly Garden has found its stride! With over 75 different native Illinois plant species we have quite a welcome charging station for butterflies and other natives. We even have a few trees (Oak and Black Walnut) growing in there, thanks to the squirrels, as well as one state-listed endangered species. :O

Why are native prairie gardens so fabulous?


1. Educational value! Dissecting flowers and identifying the male and female parts is pretty fun. There are also lots of evolutionary adaptations to observe out there, symbiotic relationships between pollinators and host plant to analyze, soil comparisons to be made, historical uses to research, and cycles from seedling to flower to fruit to blog about. It's also a great place to learn about how wildlife biologists make observations and hypotheses about nature before embarking on a field study or experiment.

2. They provide a diverse range of habitat and food for our native critters, especially butterflies, some of whom migrate 2,000 miles to get down to their wintering grounds in the southern states or Mexico.

3. These plants are adapted to the winter and come back each year in the Spring, sometimes with their babies nearby!

4. Prairie plants have really deep roots that can reach up to 15 feet into the ground. This helps create a porous and deep, fertile soil that absorbs way more water. This means you don't really have to water the plants! It also means that there is less runoff of water into rivers, creeks, and even homes with big storms. Xeriscaping - gardening or landscaping techniques that reduce the need for watering. Save money, flood less!

5. Huge variation in their heights, flower color, leaf sizes/shapes, & bloom time. Keeps things pretty and unique from spring to fall.

6. Native plants are adapted to resist the local pests & diseases that can typically destroy non-native ornamental plants.

7. Once established, very little weeding necessary! And there is never really a need for use of fertilizers or pesticides, as there typically is with ornamental gardens.

8. Lots of fun facts regarding these plants' medicinal and general uses by Native Americans.

9. Inspiration - painters, photographers, creative writers, poets, & musicians welcome. Maybe we should get some grant money for some benches!

10. I can't end on 9... hmm... I know! Gets me off my computer and back to my roots. Calming & therapeutic to take pictures, pull weeds, observe the species interactions, and take note of the variety of cycles with the plants and their pollinators.
