[Aroid-l] Initiation of Flowering in Amorphophallus

From: Gareth.Hambridge at rbgsyd.nsw.gov.au (Hambridge Gareth) on 2008.03.27 at 20:51:39(17246) Tom, I would agree wholeheartedly with Bill W. and Scott. Plenty of light, plenty of food and plenty of space. Whilst we've only flowered a few here the size of the tuber certainly suffers in a pot. The most recent flowering we've had here came from a plant that was grown in a garden bed in the Sydney Tropical Centre instead of in a pot like most our others.Over a period of 4 years the tuber weight increased from about 8kg to 26 kg whereas our potted specimens only put a few kilos a season. This large specimen flowered on the 22nd Feb. this year with a flower size of 1.92 metres. In contrast we have flowered 2 much smaller potted specimens at about 7ish kilos that gave flowers about 98cm and 120cm. It is possible that these flowered at such a small size because they were left to dry out for several weeks whilst dormant-perhaps this has some bearing on flower initiation. I know this is not recommended but a reasonable sized tuber isn't going to dessicate in a hurry. I'm guessing that drying them out is going to have some affect on the levels of naturally occurring hormones, perhaps due to stress or some other reason.
