P. 'Kaleidoscope' was the first offering from Dan Heims of Terra Nova Nurseries, Inc. (Tigard, OR) from a cross between Podophyllum hybrid 374 (an unpatented proprietary plant) as the seed parent and Podophyllum hybrid 352 (an unpatented proprietary plant) as the pollen parent. These two Podophyllum hybrids are outstanding selections out of a hybrid swarm in a Japanese nursery, believed to come from P. difforme, P. delavayi, and P. versipelle. The new cultivar was chosen for its outstanding foliage - see the patent here http://www.freepatentsonline.c...

Kaleidoscope seems to be the most hardy thru the winter of the Podophyllum for me

Now we read

Plants Delight where Galaxy comes from says
"Podophyllum 'Kaleidoscope' was introduced in 2002 as a selection from Goyoren Nursery in Japan. We went back to Goyoren Nursery for plants, and while we can't call it Podophyllum 'Kaleidoscope', we also can't tell any difference between this and the patented seedling. The original plants came from China so, although we initially assumed it to be a hybrid, it may in fact be an unnamed mayapple species."

Far Reaches Farms says
Galaxy is very close to 'Kaleidoscope' and comes from the same Japanese nursery from which a plant was purchased and patented in this country as 'Kaleidoscope'. One has to wonder how a plant already in the trade on an international basis can be patented but that is a discussion that can run long into the night. 'Galaxy' is nearly indistinguishable from 'Kaleidoscope' and may well be a sister seedling or another selection in Japan. Lightly hairy stems hold the pale green leaves with their radially symmetrical chocolate splotches. Red flowers held beneath the foliage but who cares, really? It's all about the leaves. Moist shade and be prepared to be envied.

and Cotswold gardens in the UK says
P. 'Kaleidoscope' is a Remarkable hexagonal dark marked foliage, deep red flowers May-Jun, 50cm. Shade, vigorous, tough. A selection of what might be P.difforme by Goyoren Nursery, Japan and subsequently renamed in USA.

and La Genête nursery says
Podophyllum 'Goyoren' is a Japanese cultivar related to the misshapen species. When we see the flowers, we can wonder if it is not a hybrid between P. difforme and delavayi. It seems that the cultivar 'Galaxy' refers to the same plant. A superb plant in any case.

so much confusion
