Re: Tips on Maihuenia patagonica

I put them out, unprotected, in a pot outside in late autumn and wait for spring.

Re: Aloe Variegata

Hi Martin.
Did we discuss this at Wilts BCSS earlier this year?
The second pic looks to be one of the most compact forms to me.

Interesting observation iann. Do you have a referance to work that demonstrates that? I'd be really interested in reading it.

Re: Euphorbia obesa hybrid crested

Dave Rushforth used to sell E. obesa and E. symetrica when the latter was new. When asked what the difference between them was he would answer "£1.50".

Re: Hybridisation > New Species

There are arguments that, occasionally, hybridisation occurs together with a polyploidy event. So you have allopolyploids. Here the egg and pollen process retains both or the chromosomes from each pair. The result is a plant with matching pairs of chromosomes so it can readily breed and since it has...

I only have relatively young seedlings (perhaps a few years) - mainly because they don't last much longer for me. :smile: I've been wondering abo...
