Unintentional flowers

Some of the flowers you find at the Hort Gardens came in on their own. They weren't planted but still they are worth consideration. This is Dame's Rocket (Hesperis matronalis), a common weed in Lafayette. Find it growing in the garden near Marsteller St. Picture taken May 18, 2009.

This is the commercially available geranium cultivar marketed as 'Wargrave's Pink'.

The columbine is blooming at Purdue Horticulture Gardens.

Aquilegia canadensis is our columbine native to Indiana. It's not terribly common, but a real treat when you do find it in the wild. A beautiful plant especially in a natural setting amongst the ferns and rocks and waterfalls of Shades State Park.

Fothergilla has a striking look to it, with the white pincushion flower clusters. The showiness of the flowers is due to the white stamens, there aren't any petals. There are a couple Large Fothergillas (Fothergilla major) guarding the entrance to the Horticulture greenhouses.

The Fothergilla major in the picture above is at the front door of the greenhouses.

The other Fothergilla major at the front door of the greenhouse.

Some plants are easy to identify. This dwarf fothergilla (Fothergilla gardenii) is in the Purdue Discovery Park area. The flower is getting old, notice the dropped stamens scattered on the ground.

Another view of the dwarf fothergilla (Fothergilla gardenii) around the Discovery Park buildings. They planted a lot of this here. This is not too far from the Horticulture Gardens, about three blocks west past Russell St. and Intramural Drive.

Flowering Dogwood

This flowering dogwood (Cornus florida) isn't actually in the Horticulture Gardens, but it's close by. Find it on a short walk from the Horticulture Building. Walk west down the Horticulture Mall past the new food science building and across the street to the Ag & Bio Engineering Building. This tree is at the northeast entrance to the building.

Technically the flowers are at the center of the four white bracts.

Even better than this is to take a walk in the woods where dogwoods and redbuds are blooming here and there, wouldn't be spring in the woods without them.

This picture was taken April 27, 2009.
