Brian, Just bring the seedheads inside and let them ripen until they are red. This sometimes takes a month, or more. Then clean them, wearing plastic or latex gloves, since some arisaema fruits have annoying spicules that cause a reaction in sensitive people, or if a lot are cleaned at one time. By the way, I once received a whole seedhead of A. sikokianum from someone and only a few of the fruits were large with nice round seed in them. The rest were pretty shriveled. Many even were dished--had a concave depression in each seed. I kept these separate and sowed them all. The amazing thing was that they all came up--lage and small!

The sikokianum stem has long since died back and parted from the bulb, apparently before the seeds have fully formed, the consanguineum won't be far behind, but is much plumper. Will these heads produce any viable seed? Can I induce ripening or need I not bother. Advice please. Brian Whyer, Buckinghamshire, England, zone ~8
