Dear aroidelers,

Yesterday, a packet with 4 (huge) seeds of Typhonodorum lindleyanum
Schott arrived in my mailbox, sent by a friend of mine from Belo Horizonte
(a Brazilian city). Obviously I enjoyed the surprise, but I have to admit
that I really don't know how to germinate (and cultivate) such species. I
know it is a true WD (water-dweller) from Madagascar and it was one of the
Burle-Marx's favourite to use in artificial ponds. In fact, we have a good
number of specimens growing in some government's buildings here in
Brasilia. But I'd love to know if any of you had any kind of experience
with the germination (and further cultivation) of this marvelous plant.

Hi Eduardo, if you will plant them in a shallow tray about 2 x the depth
of the seed, in straight peatmoss which you can flood, they should do
fine. Once they are about 10 cm high they will have enough roots to
transplant. Do give them a lot of light as they seem to grow weakly
under shade. Fertilize with liquid every week and do not put them in
deep water until they are 1/2 meter high.

This has been successful for me.

Typhonodorums must be one of my favourite plants. I
think they look fantastic the way they rise up out of
a pond or lake. I really got hooked on them when I saw
them used in the landscapes created by Roberto Burle
-Marx in Brasilia, Brazil.

Luckily these plants seem to have been grown in
Brisbane, Queensland, Australia (approximately USDA
zone 11) for many years and I had no problem sourcing

Dear Arno,

Nice letter! Yes, Typhonodorum is a magnificent giant Aroid, I first saw
thia at the home of the late Dr. Birdsey in Miami, Florida. His plants
looked like huge compact banana 'trees'! His bore fruit profously, and he
was very generous with visitors in giving these seeds away. I found that
if you tried planting the quickly germinating seeds in soil BEFORE all the
seed had been absorbed by the growing plantlet, the seed would rot on
contact with soil and the plantlet would die (the large seeds of the
neotropical giant aroid Montrichardia were very much alike in this manner).
I let the seeds float untill almost all the visible seed had been absorbed,
by this time there was a very well developed root system and a nice little
plant floating around, and I then planted them in a VERY sandy mix. I saw
a wonderful plant of this in bloom at a friends home, he had carefully
peeled away the straw-like covering of old petioles from around the 'trunk'
to expose a brilliantly colored inner live layer, shiny purple and cream
Good luck with all your aroids, and also with your trip to South America!
