This may not be quite as hardy as some of the species although it is being grown outside with no mulch in Milwaukee, Wisconsin (zone 5b) where temperatures have reached -10ºF / -23ºC.

The tiny spathe, only about three inches in length (7-8 cm), peeks out from beneath the leaves and pops up between them.

The thread-like spadix curves out from the mouth of the spathe for almost four inches (10cm) and then points up.

On one spathe on my plants, the spadix corkscrewed away from the spathe. "Cute" is an apt descriptive adjective for this tiny tot.

The inflorescence is said to have an apple, pineapple or bubble gum fragrance. I can't say that I noticed anything, but often spathe scent is illusive or only lasts a few hours upon opening.


Pinellia cordata New Spathe The spadix emerges from the tip of a tightly furled new spathe.

I am glad that my plants were in a pot when they first emerged. Had I planted the dormant tuber in the garden, it's likely that, in the hurly-burly of spring gardening, I would have missed seeing the foliage unfold and watching the progress of leaf growth; both fascinating processes.

Pinellia peltata Foliage Some sources insist that P. cordata is the only species with an undivided leaf. They are wrong. Pinellia peltata has a similar leaf shape without the vein markings.

If you don't have any of the Wild, Wonderful Aroids in your shady garden, you owe it to yourself to get one (any of them but P. ternata!)...you'll be glad you did. See ya' later!

More Information

Where to find Pinellia:

  • Seneca Hill Perennials - Ellen Hornig lists P. tripartita and P. Pinellia cordata 'Yamazaki' for 2003, but I got my original P. pedatisecta from her several years ago, so she may still have some.
  • Plant Delights Nursery - Tony Avent lists P. Pinellia cordata, P. tripartita and P. tripartita 'Atropurpurea'.
  • Collector's Nursery - Bill and Diana list P. Pinellia cordata
  • Paul Christian Rare Plants in the UK lists P. Pinellia cordata and Pinellia ternata (perhaps it's not such a thug in the UK?)
