When you are in the Tulsa area next, give a call and come bye. I am definitely not interested in iris or daylilies but do have plenty to share. Paul 918 850 3299

I am looking for seeds of this plant. It is also called Nigaki. Brandon on the seeds forum suggested I try this forum. If you want more information please check out this website: http://www.pfaf.org/user/Plant.aspx?LatinName=Picrasma+quassioides Picrasma quassioides is a deciduous Tree growing to 10 m (32ft) by 7 m (23ft). It is hardy to zone 6. It is in flower in May, and the seeds ripen in October. The flowers are hermaphrodite (have both male and female organs)

We did an experiment several years ago to see what system of storage gave the best germination -- planting fresh out of the fruit, drying overnight then planting, drying several days then planting, extracting from the fruit and storing moist, in the fridge, for various number of weeks (to achieve cold-stratification, assuming they might need it), and storing refrigerated and dry (as is standard for commercial citrus seed). Of all the methods tried, by far the best germination was achieved by using tsmith2579's method -- planting immediately out of the fruit. If you've never extracted Poncirus seed, be forewarned -- wear rubber gloves, or plan to have a real challenge getting that sticky, vile-smelling juice off your hands! It's no fun at all.

I have long been interested in Poncirus and have a website with details of European specimens. I'm not so familiar with US gardens, but have seen plants growing happily in New York and Boston botanic gardens. Geographically the plant in Edinburgh Botanic Garden, Scotland, is the furthest north I've located, but of course the climate is not so cold as yours. Searching US and Canadian botanic gardens and arboretums websites often fails to provide a database of plants. However, the Missouri Botanical Garden definitely has several plants growing outside and the Dawes Arboretum in Ohio lists a specimen of the dwarf form 'Flying Dragon'. Here in England I have once seen damage to smaller branches when the temperature fell to about +15F. This unexpected cold was after a period of much milder weather, and caused splits in the bark. Stating an exact hardiness is never very scientific. It all depends on variables such as duration of cold, humidity, wind, state of growth etc. Here is a link that might be useful: UK & European Poncirus specimens
