Crocus October 2008

[Guff]

Thomas, that is very nice. When I order crocus next year, I will be getting the fall ones you had suggested. Would the same leaf compost/sand mix that I use for spring crocus work for fall, or does some gravel/perlite need to be mixed in?

[David Nicholson]

Lovely stuff both Tonys and Thomas

Magnificent pictures everyone.  Tony it's interesting to see how different your robertianus is from the form I posted earlier (Reply #47). 

[ashley]

Has Crocus sieberi nivalis now been elevated to species level (C. nivalis, SRGC #2007/1018)?

Anyone?

Full species status for this taxon seems unlikely given that BM (The Plantsman, June 2002) cites variability in wild populations that overlaps C. sieberi sublimis.

I have opened two windows and compared our mutual robertianus. I think in fact they are very similar and perhaps vary slightly in shape  because of the length of time they have been open and mine is slightly pinker but this may just be the light in which the photgraph was taken. I have possibley  another two to open and I will photograph them if we get enough sun and put them up for you to see.

Don't quote me but I have yet to grow any C sieberi nivalis that I could key out as that taxa.  The overlap with ssp sublimis may be more than just geographical.

The show does go on people - wonderful pix everyone !
Thomas, I hope the weather is somewhat clement to your great display ! 

[Thomas Huber]

I hope so, too, Luc, but the forecast doesn't agree with me 

Ashley, can't tell you anything about the botanical level of sieberi ssp nivalis, but I CAN tell you,
if the seed germinates now it's likely to be NOT C. sieberi which is a spring flowering species.

Crocus robertianus is variable from white to blue. I've also seen bicolored forms and plants with
narrow petals as well as rounded petals. Mine are flowering since September and still new flowers
are coming out of the ground - see below.

13 - C. robertianus
18 - An ugly mutation of Crocus asumaniae with 14 petals, 7 styles and anthers  
01 - C. wattiorum - one of the best in autumn
07+06+03 - different forms of C. biflorus ssp melantherus, the autumn flowering biflorus ssp with black anthers
02 - C. cancellatus ssp lycius
21 - This one came to me from Dr. Kerndorff. It looks like a pink mathewii but was ID'd as C. pallasii
47 - C. banaticus 'Snowdrift', received two years ago as two tiny corms, this year I've 3 flowers!
41 - C. goulimyi ssp leucanthus, the pale ssp of goulimyi from SE-Peloponnese


OLEG: Your blue crocus is C. speciosus!

Spectacular

Thomas,
stunning ! 
C. pallassii is a little treasure !!

Thanks Tony and Thomas. 
Interesting point about germination time Thomas; I hadn't noticed before that spring flowerers germinate later 
Yes the robertianus form I have is very much at the rounded, white end of the spectrum compared to yours and Tony Willis'.

[Gerry Webster]

A spectacular display Thomas. Congratulations!

Does the C. asumaniae show these multiple structures every year or is this a one-off? If the latter, I suspect it is the result of a physiological disturbance rather than a genuine mutation. The saffron crocuses seem prone to doing this - I posted a similar C. cartwrightianus recently. 

[Thomas Huber]

Thanks for the compliments everybody!

No, Gerry, it doesn't show the extra petals every year - first time since I received it in 2006.

[Oron Peri]

Thomas,

Beautiful species,
do you know the origin of this particular palasii?

It is really interesting.

[Maggi Young]

Thomas, is this "pallasii"  Crocus pallasii hkep9814 2008-10-07-21.jpg not look more like a Crocus asumaniae? I see it has a good provenance... HK and EP!!
