Every few years, more than 200 species of plants bloom, producing a spectacular carpet of purple, pink and yellow flowers on the desert floor. Many of the species are endemic to the area, including nolanas, huillis, and añañucas.

"There are something like 3 billion people on Earth that don't consume energy. 


No-one in this world consumes no energy.

I am an aroid fan, no matter the "scent".....

That said, there are plants beyond number that have neither scent/smell nor copious nectar, for which we know of no specific pollinator, or how/why they do the deed, albeit we humans do not have the senses of invertebrates, or even very many vertebrates (ever smelt the pheromones of a moth?).

Nature is indeed a wonderful thing.

As above.

Quote from: Martin Bohnet on October 20, 2022, 08:50:16 AMActually, Methane gas heatings may have up to theoretically 111% efficiency

That would asume no chimney/flue gases.
Nothing legal would be allowed to be unvented - some heat will always be lost up the flue and combustion requires introduction of new air (oxygen), even if supplied direct to the burner rather from the greenhouse itself.

I suppose you could get close to a real 100% by running the flue pipe around any greenhouse, or even use an intercooler - flue/supply gas heat-exchanger - so that the gas that eventually exited was very close to greenhouse temperature, or even below, but the extended flue would probably have major problems with condensation/corrosion and any inter-cooler would have to be (very) large. None of it an engineering dream when it would all have to rely on convection and/or chimney/pitot effect.

Thanks for the information.
The plant is in a very gritty compost in a clay pot and it may be an optical illusion that it has made less than 1mm of new leaf growth beyond the tunics so far.

It will get a drench every 7-10 days and will likely dry out between.

It has been for a long while this year - NL banned export of cucumbers a few months back and there was recently an early morning report on the farming programme that large parts of the Lea valley horticultural area have been sold off for housing development as a consequence of growing becoming uneconomic.

Thanks Marc - bottom heat here is generally around 20C anyway. In an enclosed space, this means close to 20C air temperature.

(We are a hardy lot here in the UK - unless we are relaxing at home, vegging-out, during the day, household temp's will drop several degrees under that during the day. Even more so with current energy prices      )

The supplier of this to me, in the UK, has never flowered this plant. 
Another UK source of information suggests that it is a pink form of R. bagnoldii, in which case it would probably be from very sandy habitat with infrequent heavy rains, and winter-growing.

Does anyone know the plant, or even better, has anyone flowered it? Better yet, would they care to share?

I knew that Crinum were fast to germinate - hence my surprise when none had geminated before they arrived (last year I bought some Crossyne seed and they had all germintaed in the packet, before arrival).

I did check after my last post and one Crinum seed has a very small root. I have moved them to a heat pad set at 20C, which may be better, even though they are indoors so do not get cold.

Thanks again

Hi Uli
Many thanks for the comment. The seed was sown the day that it arrived - no germination as yet, which is a surprise, although some have expanded. I may soak the ones that have not, as you suggest.
My name was mentioned before - Carl

I recently bought some seed and had expected it to have produced shoots before it arrived, but not so.

The seed had obviously originally been roughly spherical, around an inch diameter, but the seed arrived as what look like large segments from an orange - maybe 3-4-5 per whole. As the segments are covered in the same seed-coat all over, the seeds appear to be whole, even though the few online pic's of Crinum seeds show whole, spherical seeds of varying sizes.

Is anyone familiar with the seed able to comment?

Triploid?
