Typhonodorum

From: eduardo gomes goncalves <eggon at guarany.cpd.unb.br> on 1997.05.16 at 21:48:06(747) 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. HELP ME, PLEASE... +More Best wishes, Eduardo.

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.

My friend Eduardo, Once again, I`ve grown this! Put the seeds to float in a bowl of water, they will put up a long (2")"stem" and roots (about 2-3 weeks or longer!), at which point you pot them up as you`d do other water dwellers. I found that if I put the seeds on soil too early, they rotted at the point of contact with the soil. You could also try germinating them on wet sand as in Urospatha and Dracontioides where the developing roots had something to go into, but the float-in-water method worked perfectly for me, 100% sucess. I will copy a very informative article on the propagation of this plant from "Aroideana", Vol. 13, 1990, and get it in the mail together with the photos I had previously mentioned, today. Good growing! Julius ju-bo@msn.com

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 plants. +More For the last 3 years I cut the old flowers off my large (2 metre tall, 7 foot) Typhonodorum which grows in a pot in my pond. I was under the assumption that cross pollination between different plants was needed for seed. 2 years ago I purchased 2 more plants which will probably start flowering next summer. The idea was to have flowers to cross pollinate. After reading some comments on the list about self pollination on these plants, I left the flowers on my older plant. On Sunday I noted the spath of one flower had opened a little and the fruit were loose. It is now the heart of winter and really cold for us Brisbanites. The days are warm and sunny in the mid 20's but the temperatures are diving down to 6 and 8 degrees C at night, with frosts in inland areas. Also my pond is in an area shaded by trees during winter, and the water doesn't get warmed by the sun. Given the season and the brown mush of fruit and seed in the bract, I didn't expect to find viable seed. However on cleaning I found 9 large seeds. I placed the cleaned seeds in a pan of water Sunday night. Inspecting them on Tuesday afternoon I found two had shoots 2 cm long (an inch), and others were sprouting. I find this amazing given current temperatures in my house. For a tropical plant, this plant does well in our subtropical climate. I'm looking forward to raising the next generation, however it looks like I'll need to find homes for some of these plants, or dig a bigger pond. I find the root systems of the plant amazing. I repot my big plant every 2 or so years. most of the roots seem to be outside the pot and its a major struggle repotting. Maybe I'll have to look at putting in a permanent sand bed at the bottom of my pond. ===== Arno arnoking@yahoo.com __________________________________________________ Do You Yahoo!?

From: "Julius Boos" ju-bo at msn.com> on 2002.07.04 at 23:47:16(9077) 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 stripes!! Good luck with all your aroids, and also with your trip to South America! Julius +More Boos West Palm Beach, Florida U.S.A. >>Typhonodorums must be one of my favourite plants.

From: GEOFFREY KIBBY <fieldmycol at yahoo.co.uk> on 2014.07.03 at 22:25:05(22995) Hi all, Has anyone had any experience of sowing and growing on seeds of Typhonodorum? I have 10 very fresh seeds, already starting to germinate and I wondered just how wet they should be... I know adult plants can grow in deep water but should the pot in which the seeds are sown be completely submerged or just standing in water? Any suggestions appreciated.
