I have one growing in my planted tank.
Some of its leaves are close to 1m long.
Where did you source yours from as I would love a couple more.
Mine is growing in eco complete, under a 150 watt halide ,has CO2 injection and I dose EI method.
Hope those details help

I only have 8 bulbs which I have had in a hanging basket for years, but have only recently realised what species they are . Sorry, the spares have already been spoken for, in fact if I had 100 I could find homes for them all.
I would like to try a couple in my Malawi & Tanganyikan tanks which have 1 to2mm "Crushed Coral" as a substrate but not sure on how they will go.
Different websites state that they will grow under "Low to High" lights in most substrates which doesn't really tell you a heap.
If you have any info' on growing them I would really appreciate it if you could let me know.
Cheers

Scientific name: Crinum thaianum
Common name: Onion plant
Light requirements: Medium
Difficulty:Medium
Aquarium niche:Background
Care: Crinum thaianum needs a nutrient rich substrate and moderate lighting, and will grow quick if its requirements are met. Propagation rare in the aquarium.
Does that answer your 2 questions?

the only extra piece of info I can give is that I have put a lump of "Dino Dung " under it.
http://www.aquagreen...osaur_Dung.html
This will give the roots added nutrients.
I could be wrong but I think aquatix has it...... If not just do what I do and order from Aquagreen direct.
I havent noticed mine growing any daughter bulbs (YET )
Good luck with yours
here are a couple of aussie other posts that you may find some info from.

Many thanks for those links, they were just what I was looking for.
I did a "search" on that site, but I couldn't have used the correct words.
After reading the links I will try one in the pond. The flowers are just fantastic.
The 8 bulbs I have were originally in a hanging basket, I planted them in full shade 2 years ago & the biggest bulb has a couple of 10mm bubs already.
Thanks again, will let you know how I go with them later.
Thanks again

I can't remember where I got them from. I have had them for several years now.
It wasn't until I was looking for another plant that I came across some info' on it remembered that I had some.
I originally bought 2 bulbs & they have multiplied over the years & now I have 8 varying from 5cm down to 3cm diameter, plus the largest one has 2 bulblets on it.
Since I planted them in a shade garden on a South facing wall 2 years ago they have been largely neglected, so I assume with an enriched soils & better care they will reproduce more.

Please tell me my ID is incorrect as I don't know if I want to risk losing them by trying them in the Tanganyikan tank.
Photo's as requested, including close-ups of flower bud & bulbets.

heres some pics of mine
once it flowers it will be easier to identify but im guessing what you have is a native from the Amaryllidaceae family

I am pretty sure the plant I have is not Crinum Thaianum.
I placed all 8 bulbs in a bucket filled with gravel & water. The roots on all of them have rotted off.
I have now cut back all the leaves and planted them in a pot of soil & now waiting to see what happens.
Although disappointing, it will be interesting to see if they flower so I can ID them properly.
Apologies to those who wanted some bulbs.
