  Typhonium lindleyanum autumn treatment
From: magrysbo at shu.edu on 2001.10.08 at 19:46:33(7566)
My 4 plantlets of T. lindleyanum grew a few extra inches/a few leaves this spring and summer, up to 9 inches tall. The 2 in pots sitting in trays of water did better than the 2 in ground. Now we are getting occasional nights down to 50F here in New Jersey. My question is, will they go dormant just like Typhonium venosum, should I start drying them out now. If not, how long can they be left outdoors here. Will they be damaged (root-wise) by a touch of frost? What kind of tuber or rhizome do they have? I can bring them in and dry them out now, or keep them going under lights as they seem to want to be making more new leaves.Please advise us who have received these plantlets.Bonavenutre Magrys

Dear Bona venutre,

I THINK you are mistaken about what your plants are, there is a
Typhonodorum lindleanum, not a Typhonium! Typhonodorum is a HUGE
(grows to about 6' tall, looks like a banana 'tree'!), aquatic aroid from
Madagascar and nearby Islands, it MUST be kept wet and warm! Check
w/ Brian Williams, he distributed seed of this about a year ago. I
believe Brian has heaters even in the water, as the roots suffer greatly in
winter when the water gets cool. The larger plants develop a
'knot'-like structure at the plant`s base, but I would not call it a tuber,
and it does not go dormant! There is a great article on growing
this wonderful giant aroid in Australia in a back-issue of Aroideana (get your
back-issues while they last!).

Good luck,

OK great! Thanks Julius. They are looking like little banana trees. They're
all in pots now, sitting in a tray of water on a terry-cloth covered
radiator next to my Phalaenopsis. Thank you also Brian! Can't $$ back
issues now, but I'd like to see that article sometime. Are they gonna take
over my living room?

You are welcome, Bonaventure!

Remember to put a layer of larva rock or stone, broken croc or whatever in
the bottom of their pots, this will keep the potting soil/mix ABOVE the
level of the water in the saucers, otherwise the soil will rot, stink, and
kill the plants if emersed under water! You have to water from above till
you see that the roots have emerged out of the drain-holes in the pots`
bottoms into the water.
Depends on how big a living room you have---at the very least, they should
grow to 4-5' with a 4-5' spread, IF you can supply enough heat and light!
They are considered one of the 'giant' aroids!

Good luck,
