Asimina triloba

The unique flowers of Asimina triloba (Pawpaw, or [insert state or region here] Banana) were in anthesis today at Potato Creek State Park in St. Joseph County, Indiana.  I was shocked to see that we previously had no images of this species on Get Your Botany On!, so I figured I should post the photos I captured.


As interesting as these flowers are, because of their color, they are often overlooked.  I had walked past several flowers at eye-level before noticing those in these photographs. As is often the case with flowers that are this color, an unpleasant odor is emitted by the flowers, leading to them being pollinated by insects such as carrion beetles, carrion flies, and fruit flies.

Notice how the naked (scaleless) buds open directly into the leaves - a characteristic used in winter to identify this attractive clonal tree of the primarily tropical family Annonaceae.  Pawpaws can be found in rich mesic forests throughout the eastern half of the United States.


In these photographs, the paired flowers have a look that reminds me of wedding bells.


In 2009, the Pawpaw was designated as the state native fruit of Ohio.  This must have had something to do with the colossal collapses of late by my Buckeyes in major sporting events... if not the fact that the fruit of Aesculus are poisonous whereas those of Asimina triloba are delicious.  Good luck collecting Pawpaw fruits in the summer, though... the raccoons and deer often feast on them before we have a chance.

Land of Flowers 5

Asimina angustifolia
This pawpaw was growing in a very sandy soil in a sunny powerline corridor in Madison County. It was a frequent low-growing shrub. I imagine that the gopher tortoises like the fruit.

Campanula floridana
This flower was frequent in the under-grazed sections of the cattle pastures in Okeechobee County.

Kalmia hirsuta
Hairy Wicky was growing in a wetland right on the county line between Madison and Lafayette County.

Passiflora incarnata
This passionflower was growing in the same sandy, sunny powerline corridor as the pawpaw in Madison County.

Richardia grandiflora
This attractive weed was growing along the shoulder of a highway in Martin County.

Ruellia caroliniensis
This wild petunia was growing along the margins of wetlands in Levy County.

The land of flowers

It is fun to see things blooming again. I am sure there will be more pictures as I get a chance to process things.
Bidens alba - Romerillo

Lindernia grandiflora - Savannah False Pimpernel

Asimina incana - Pawpaw
It is very cool to find out that there are other pawpaws out there in the world.

Vaccinium myrsinites - Shiny Blueberry

Gelsemium sempervirens - Evening Trumpetflower
This native is so prolific that it seems like an invasive. The flowers are gorgeous.

Houstonia procumbens - Roundleaf Bluet
Blooming at Hillsborough River State Park
