Blue mistflower

Eupatorium coelestinum is a synonym for this native Indiana flower, currently the blue mistflower is placed in the Conoclinum genus as Conoclinum coelestinum.

Link to botanical treatment of blue mistflower:

Conoclinum coelestinum looks a lot like its relative white snakeroot, but it has blue flowers instead of white. White snakeroot is everywhere in the woods, but blue mistflower is much harder to find.

Obedient plant

This is the obedient plant, Physostegia virginiana. The cultivar is 'Pink Bouquet'. It's fun to push these flowers around. Be careful if you plant it, it has a tendency to become invasive. Picture taken August 27, 2009.

Zinnia marylandica with Painted lady

A painted lady butterfly (Vanessa cardui) feeds on Zinnia in Hort Gardens. The Zinnia is Zinnia marylandica 'Zahara Rose Starlight'.

Zinnia marylandica is a hybrid of Zinnia angustifolia and Zinnia violacea. I suppose the plant breeders were trying to get the look of Zinnia violacea without the mildew but it still looks like Zinnia angustifolia to me. Picture taken August 27, 2009.

Block P with Lysimachia

Lysimachia nummularia 'Goldilocks' is growing on the Block P here in front of the greenhouse. To the left is the Ensete and to the right is the Musa basjoo. Picture taken August 15, 2009.

Link to Lysimachia nummularia:

Lysimachia nummularia can be found growing wild in many places in Indiana, often in spots that are periodically wet. It's not native, but it spread from people's gardens many years ago.

Mandevilla splendens

This pot was supposed to contain Stephanotis floribunda, hence the label, but this pink flowered vine turned up here instead. It's not Stephanotis but Mandevilla splendens. You can find a larger Mandevilla splendens vine at the base of the wooden deck in the center of the gardens. Maybe the Stephanotis will appear later.

Stephanotis and Mandevilla don't look much alike, but they're both in the dogbane family of plants (Apocynaceae).

Gaura lindheimeri is native to Texas. Our own native Gaura is Gaura biennis. Instead of planting foreign plants and risking the spread of them outside the garden, why not find some of our own Indiana native Gaura biennis and put that in your garden?

Amaranthus tricolor

This plant is Amaranthus tricolor 'Joseph's Coat'. The label in the garden also calls it Summer Poinsettia, which is an ill-advised name for it. As one of the amaranth family of plants it's not related at all to real poinsettias, which are in the euphorbia family. You can't eat poinsettias and other euphorbias, but like many of the amaranths, this plant is good to eat. Picture taken August 11, 2009.

Blackberry lily

Blackberry lilies (Belamcanda chinensis), at Purdue Horticulture Gardens, at Marstellar Street, August 7, 2009. Come back to this plant later in the year to see the distinctive blackberry seed cluster.

Belamcanda chinensis could be an obsolete name for the blackberry lily, its closest relative has been shown to be an iris, Iris divaricata, and a new name, Iris domestica, is proposed:

Black-eyed Susan

Here are three kinds of black-eyed Susan (Rudbeckia hirta) planted at Purdue Horticulture Garden. This is Rudbeckia hirta 'Cappucino'.

Link to Rudbeckia hirta:

This is Rudbeckia hirta 'Denver Daisy'.

This is Rudbeckia hirta 'Cherokee Sunset'.

These cultivars are a bit more showy than our native Rudbeckia hirta, which is usually seen with plain yellow ray flowers. Commercial cultivars like these are being spread all over the outdoors though, no doubt they will persist to replace the old kind in many places. "Wildflower garden" is an oxymoron. If you plant it, it's not a wild flower. If you wish to reestablish prairie land as a native ecosystem, take care that you use plants that belong there.
