  Seed Germination
From: Don Burns <burns at mobot.mobot.org> on 1999.03.02 at 02:59:43(3088)

I am assuming for a moment that because you addressed your inquiry to the
Aroid list you want information on stimulation of germination in the
Araceae. Not that there are none, but I am unaware of any publications
devoted to techniques/problems in germination of seeds of Araceae. My
limited experience (primarily tropicals) suggests that seed germination in
this family of plants is in general rather simple. There are exceptions
and some have been discussed here, the most recent being germination of
Amorphophallus henryi.

On the other hand, if you are interested in germnination stimuli in other
families, I suggest you review "Seed Germination Theory and Practice", 2nd
ed., by Norman C. Deno. Deno has also published a supplement to the 2nd
edition. In these publications are the results of his experiments with
numerous genera, stimulators and inhibitors of germination.

As to seed germination of anthuriums, I have sprouted thousands from
greenhouse produced seed and collected seed from the wild. I clean the pulp,
spread the seed onto good damp potting soil within a closed terrarium setting
and put under lights. Most do very well in a fairly short time. Others take
forever. And, of course, some take the heavenly route. The hardest usually are
those that you are just dying to see and to have to live. Perhaps the most
difficult I ever had and failed with production of mature plants, was
anthurium cutuense from the southern mountains of Ecuador. I could get them to
sprout, but getting them to grow was not within my realm. I tried
transplanting into several mediums and each appeared to be just what I needed
and then, as you have already guessed, they failed. I have grown anthurium
peltigerum from seed several times from collected seed. The hardest part in
general has been the transfer of reasonable size seedlings into solo
situations and out into the open. Once they get adjusted nature takes its
course. If they can stand our summer heat or the winter heat in the
greenhouse. Another set of fun conditions to find in which each can survive.

There is great joy in waiting and watching and participation in the cycle of
life again and again. I think many of you have different genera that fascinate
you and I would imagine go thru similar tribulations as I have with the

Speaking of germination, I am working on some seeds which were sold as "Lily
of Kenya." To judge by the picture, it is obviously a Zantedeschia, most
likely Z. elliottiana. I first soaked them for several days until they
softened a bit, then placed them in a pot on top of the refrigerator, with a
tray underneath so I could bottom-water. Will this work, and how long will it

Well, Jason, I grow three of this genus, but have never tried to germinate
the seeds.

Did a bit of a hunt in my files of posts from Aroid-L and discovered that,
using fresh seed, they should germinate in a couple of weeks. I didn't
find any references to seed that may have been stored dry, but I imagine
that if it is viable, it should not take more than a few weeks to sprout.

One person said that a 24 hour soak wouldn't hurt and they put them in a
zip lock plastic bag with coarse peat at room temperature until they
germinate at which time he plants them in potting mix.

Another comment was that they did not need to be continually wet to
germinate. My reading of this was sitting in water.

Personally, I water all my seeds from the top...otherwise they'd never get
watered;-) But, I also top my seedpots with grit and water gently so the
stream doesn't dig holes in the mix.

What you're doing ought to work if the seed is viable. I would be patient
a bit if you don't get germination in a couple of weeks and the seed has
been stored dry...that can often cause things to slow up a bit.

Be interested to hear if they do germinate and how long it takes....

I have just finished harvesting seed from my Lagenandra ovata and have seed
ripening on a Montrichardia linifera. Does anyone know if there are any
special conditions I need to address to sprout them?

Dear Craig,
I know about the Montrichardia seed, they will fall off the spadix when mature, clean them, and float them in a large bowl of warmish water (80 deg. F.?) in a well-lit area, they will produce good roots while floating in water, when they have two or more 'pre-leaves' and lots of white roots, plant them in a pot with sand-on-top-of- soil mix, 2" of crock or larva rock BELOW the layer of soil in a saucer of water about 1 1/2" deep, the soil is kept from being UNDER the water level. If the remaining seed contacts actual soil-mix they tend to rot, hence the layer of about 3/4" of plain sand on top of the soil-mix.
Where did you get the mother-plant, and how did you fertilize to obtain fruit??
The Best,

Hello Julius,

Thanks for your help and I hope I'm not being presumptous about the fruit, but I can send you of what I think are fruit.

I got the mother plant from a mutual friend, Richard at Mesozoic Landscapes. I grow aquatics and he brought it to me last year when he stopped by my nursery to get some Victoria waterlilies. To fertilize it, I just tried plain old hand pollination, but there could have been some rogue insects involved as well.

Hello Craig,
You did my old heart good, the chickens have come home to roost, so to speak. The original collection of seeds that produced the parents of your plants ( that you got from our mutual friend Richard) were collected in Nariva swamp of the E. Coast of Trinidad, W.I. by my elder brother Hans who still lives in Trinidad, Richard and myself are old friends dating back many years, he is a great guy. I`m just glad that both his and obviously your plants of this wonderful genus are doing so well, his are the size of the parents, I get such a thrill when I visit him and see the size of his! We still are not certain how his are pollinated, as big bees and scrab beetles are the pollinators in their native habitat, but they smell sop fragrant I`d not be surprised if SOME insect is attracted to them at anthesis. There is a
dwarf clone of Montrichardia in Florida that I collected years ago, Charlie Mc Daniel has it, no taller than 5 ft., thin as your finger and blooms at this size.
So glad that I solved this one! Thanks for the info. By the way, the seeds are good eating when roasted according to Pete Boyce who ate them w/ the natives in Brazil. The infructesence looks like a small, really knobby pineapple
Good Growing,
