Ageratum (Floss flower)


This is floss flower, Ageratum houstonianum 'Leilani Blue'. Picture taken September 24, 2009. Be careful, there is another plant at Purdue Memorial Gardens that looks much like this and has a similar looking but different name, that is the Hardy Ageratum (Blue mistflower). This is confusing! Considering the potential for Ageratum houstonianum for invasiveness, it would make sense to be sure to only plant our native blue mistflower.

New England aster



What we call the New England aster is native to Indiana too. It appears in old fields and woods edges as clumps of purple flowers in a perfect complement to the yellows of the goldenrod that grow there too, and nobody plants it. It's just there, as much a part of the Indiana season as the red leaves of sumac or football.

Aster novae-angliae is an obsolete botanical name for the New England aster, recently botanists have decided that the North American asters should be pretty much placed into a separate genus from Aster, that genus is Symphyotrichum. The current name of the New England aster is now Symphyotrichum novae-angliae (L.) G.L. Nesom. The L. in parentheses stands for Linnaeus who gave this plant the original name of Aster novae-angliae. The G.L. Nesom outside the parentheses is the guy you can blame for having to change all the paperwork referring to this plant.

The pictures here are of a dwarf commercial cultivar of New England aster called 'Purple Dome'. You can find the plant in the pictures at the Purdue Horticulture Gardens behind the Horticulture Building on campus. These pictures were taken September 10, 2009, and the plant is just beginning to flower, the flowers should be more profuse by now.

Kousa dogwood with fruits


This Kousa dogwood (Cornus kousa) is just outside the front door of the greenhouse. In the springtime Cornus kousa has showy white bracts around the flowers that look much like the native flowering dogwood common in our woodlands. The fruit is said to be edible but it doesn't appeal to my taste. Maybe yours. Picture taken September 10, 2009.

Moon Vine


The morning glory vine with the big white flowers and cordate leaves is Moon Vine, Ipomoea alba. Picture taken at Purdue Horticulture Gardens, September 1, 2009.

There's another plant that's commonly grown in these parts that we call moonflower, it has big white flowers too, but that's a Datura, not an Ipomoea. Don't get the two confused, they're completely different plants.
