  Zantedeschia availability??
From: "Julius Boos" ju-bo at msn.com> on 2002.05.02 at 04:34:41(8704)
Dear Folks,

I am loking to aquire/buy a few doramnt tubers of Zantedeschia
aethopica (or any large, white spathed clone) for a friend here in S. Florida
who wants to grow it 'wet'. Does anyone know the warmth/cold
requirements of this genus??? Is there a species or clone that will
grow eell wet and warm??

I look forward to your replys!

My experience is that most of the cultivars of Z. aethiopica will love it wet
and warm. It is often grown standing permanently in water in botanic gardens
here and the only problem I would forsee is that it grows VERY fast under
such conditions. There are of course both short and tall cultivars (up to 5-6
ft is not unusual), the shorter clones tending to have much more open,
flatter spathes ie. Z. aethiopica 'crowbrough'. I prefer the taller forms
which have beautiful tall, often tightly furled spathes.

Zantedeschia aethopica grows so well wet and warm that it is regarded as a
noxious weed in many parts of Australia. It colonises coastal waterways in
many parts of Aus and can become quite a pest. I do not know what you mean
by "warm" but I am talking places that in many cases never get even close
to a frost, let alone actually getting one. These tend to grow in the
swampy conditions on waterway edges.

I would assume that the varieties we have here in Australia are nothing
particularly uncommon, so I figure you should be easily able to get a warm
and wet variety for your friend.

I hope this is of some help.

Z. aethiopica grows well here in North Carolina (zone 7) in spite of
getting zapped every
fall by the frost. It's native to South Africa (zone 10) and loves the
warm weather.

This may not be what you are looking for, but I hand pollinated my "giant", "herculies" or whatever other cultivar name you want to give it (the mammoth white one with the white spots on the leaves).

The infruct. is quite huge and I am sure the berries will be ripe soon.. I will be looking to keep a bunch for myself as this cultivar is so gigantic and amazing.. but I will have plenty to spare. If you or others would like some.. feel free to let me know.

Also, I grow one in a reletively dry area... I grow one grossly wet..both in the heat (I am in S. Florida as well) and the winter temps dont bother them at all and they dont go dormant for me. It is about as adaptable as it gets... I only notice that it flowers infrequently in the summer? Heavy in spring and fall...also fragrant (from close up :)

(with all of that said...the berries are currently very big and swollen.. but juuuust turning a lighter shade from the "green" they were..how long should these things need to go before they are fully ripe?)

For me here in Zone 6, I have grown a zantadeschia unknown white hybrid in a
pot sunken in my water garden to a depth of 3" above soil level. It
thrives. Maximum temp survived is 95+ with this method. Leaves burn in
full sun. I have grown this in regular conditions with same results. A few
volunteers have regularly come up every year with no special treatment.
Bulbs multiply very rapidly in good soil, less so in water. One of my first
aroids! Seedpods tend to droop without full sun, but that makes more
volunteers! Happy to share a couple if you want; I gave away most last
fall, but still have some and will have many more by fall!

Thanks, Geoffrey!

It will be a help when I obtain some for my friend!

I just looked on Google to see what the heck a Zantedeschia looks like.
Surely you are not talking about the calla? It is invasive here. In fact,
if you make the mistake of not pasteurizing (or discarding) media from a pot
that once grew calla lilies, and if you attempt to reuse the media, you will
have them coming up in whatever you put the media in. Even pasteurizing
doesn't kill the larger tubers but, hopefully, you will have screened your
media first to get those out.

The ones that are the worst are the common white ones. Hopefully the more
beautifully colored ones are not so ninja.

In my experience, you cannot give them too much water, but they tolerate
clay soil just fine, even in a pot, so keeping water on them is usually not
a problem. Don't give them good media with good aeration because it will
just encourage them.

Drooping seed heads are one of the characteristics that distinguish one
species from

All my callas came from a single tuber; as a regular thing, the ones planted
where they receive more than 6 hours of sun/day (full sun) stand up
straight; the ones that receive <1 hour sun/day droop. The ones that get
from 1-6 hours kind of droop. I assumed it was more a function of the
amount of sun received rather than dependent on the species. No, I don't
deliberately place any of mine in full shade; these are mostly volunteers,
or maybe from seed harvested by various insects/rodents and stored that have
later sprouted. I come across them from time to time. They seem to survive
our winter here (zone 6) with only the natural leaf mulch in our woodland.
