4 "unknown" Petrocosmeas

4 "unknown" Petrocosmeas

Postby Reinhold » September 30th, 2012, 9:00 am

Hello to you!
I am new to this forum and would like to show you my 4 Petrocosmeas.
Well, when I got them, they just were given numbers 1..4 but no names.
I tried to find their proper taxonomy by comparison with pictures on the internet.
Please let me know whether you agree.
Thanks a lot
Reinhold

Reionhold, I have all the varieties that you mentioned in your post, except P. minor, I will check it for you :-)

The last one is P. rosettifolia for sure!

Wow, P. rosettifolia has so many flowers and buds! It is awesome!

Have you looked also on the pictures from this subforum of petrocosmea? Lola and Svetlana have a lot of them. :)

Right now she has got about 60 flowers.

We were discussing why that would be so. But we found no one reason.
Could it be the result of better fertilizing or is it due to the plant being somewhat grown up?

I think fertilizer has an impact on the flowering habit. Actually I'm also regurarly fertilize them, but mine not receiving that much light, so I think light can be an indicator too.

The most important factor is light! I see your plants' leaves are tight and short, this mean it receives a lot of light. And the flowers are the usual reaction to this amount of light.
