Subject: Re: Taccarum
Here in Brazil I grow two species: Taccarum weddellianum and Taccarum
warmingii. The other three species are T. cardenasianum, T. caudatum and
T. peregrinum. Last year I traveled more than 2.000 km to look for the
last one (T. peregrinum) but El Nino make the rainy season shorter in
Northeastern Brazil and all plants was dormant when I was there (there
was no way to find them in the field!). I will try again later. In
January I will be in northwestern portions of the Cerrado province
(state of Rondonia near the Boliviaīs border) to look for a possible T.
cardenasianum. The species is from Bolivia, but there are interesting
Andean remnants in some higher places of western Brazil, so I think I
have one chance in 100!
In my plants, the tubers of T. weddellianum are smooth and with
yellowish patches. In fact they have beautiful tubers, as Julius told!
All my plants of this species are still young, so I donīt wait blooms
for the next two years.
All T. warmingii clones I grow (3 or 4) donīt have that smooth
surface. They have the texture rather similar to Taro tubers, altought
they rounded and flattened apically. One of the most interesting thing
in such species is the base of petioles. They are red (just like blood)
in fertile plants and one I colected in the state of Goias had the base
of petioles bright yellow. It was really terrific! My biggest tuber is
spected to produce inflorescenses this year (our growing season are just
starting here in the Southern portions of the world).
In my experience, Taccarum is hard to kill (I am the best one to
talk about this, because I was able to kill all my Sauromatum venosum!)
but donīt produce offsets usually, altought they can be divided. There
was a time that I collected a plant of T. warmingii in the field and the
tuber split when I tried to bury it, so I stored the two halves and both
sprouted in the growing season. I grow mine in my "all-purpose mix for
tuberous things", that is a misture of limestone grit, Dicksonia fibers
and cork. It is very common to find wild populations of Taccarum in
limestone outcrops here in Brazil (they grow in crevices in the rock) so
I think limestone is good for them.
Letīs wait for contributions of other "Taccarophiles"!
