Arum Fruit - What to Do?

I have some little red Arum fruits in a dish, that I harvested yesterday. What do I do with them? The plant that produced them is long dormant, and since it took about 4 years for it to flower the first time, I was totally unprepared for them. And, of course, I have lost the label. I guess it will be next year before I can identify it.

I would sow the seeds (take away the pulp) early this autumn if I wanted more plants. Place the pot outside but cover against birds, rodents etc.

I've never grown Arum from seed, in fact, have no Arum in the garden...no particular reason, it's just that I haven't gotten around to trying them yet... I do like the Araceae.

But I would be tempted to treat the seed as they might be treated in nature; that is sow them now with the pulp on, but sow them in place outdoors, possibly close to the parent plant.  I use this lackadaisical direct-sowing-in-situ technique for Arisaema seed all the time, and the seed comes up the following spring.  I have also spent time removing the pulp and sowing, maybe that guarantees a higher percentage of germination, or hastens germination, I'm not sure, but the easy direct sowing method works for me.

The pulp often contains germination-inhibiting chemicals. But if the seeds stay outside all winter I think that doesn't matter as Mark says.

Hi Peter:  I, too have a nice Arum which has recently fruited.  This is Arum maculatum which did very well in a shady spot this year. I collected the orange colored seeds, removed the pulp and put the dried seed in an envelope in the frig - plan to put them into the Seedex this year.  Incidentally, the plant was brought home from Wisley Garden in the UK.  Fran Howey
