Spring Crocus 2010

Submitted by Mark McD on

I started this thread "Spring Crocus 2010" to post photos and information on the popular spring crocus. This year has been the mildest and earliest spring flowering ever, advancing the season for "first bulbs" by two full weeks over the last 10 years, with lots of species and hybrid crocus pushing the season to an extraordinarily early start. One species that is barely visible one day and all of a sudden after a warn day leaps forward into full flower is Crocus kosaninii.

I received the plant as C. biflorus ssp. pulchricolor, however it is a mistaken ID, the plant illustrated is most likely C. kosaninii. The first photo shows early anthesis with lots of very small perky flowers, with many more buds coming. It is a bee magnet.

Not familiar with that species...looks partway between a tommie and etruscus.

I'll win the prize for the latest crocus to bloom..I usually have some that make it to late May.  It will be mid-April before my show really begins...most of you will be finished then.

Here are some of my plants. I am not sure of the names, many cross and self-sow here. We have had a very fine day today, reached the 10C mark! However I was too late home to catch the blooms fully open.

Trond, I think you have, in order, C. etruscus, C. tommasinianus 'Ruby Giant' and C. chrysanthus 'Gypsy Girl'...Mark can probably verify if this is correct.

I have three cultivars open today...C. chrysanthus 'Gypsy Girl' and what I think is C. tommasinianus, although they look surprisingly like Mark's kosaniniii.  The second photo is either C. chrysanthus 'Cream Beauty' or 'Romance'


Submitted by Boland on Tue, 03/23/2010 - 16:56

Trond, on second thought, the crocus I ID'ed as 'Gypsy Girl' is more bronzy than mine, so I think it might in fact be 'Fuscotinctus'.

Hard to tell until the flowers are open to see stamen and stigma characteristics, so Trond, please post photos again of these same plants if you're able to catch them open.  Regarding C. chrysanthus cultivars, a Scottish Rock Garden Society member created an excellent photographic essay that diagnostically shows various chrysanthus cultivars... I'll find the link and post here.

I believe the C. kosaninii has a different disposition... thin narrow tube, small flowers, and a dark tube where the color ascends part way up onto the petals on the outside, although photos of this species from Serbia show lots of variation.  Also note the stamen and stigma differences.

On the C. chrysanthus cultivar, I would go with 'Romance', based on the light yellow flowers with the outer petals near white at the apex, see:

This has been my great frustration when I was working, asking myself over and over again: "why do I plant species crocus?", I almost never get to see them open, and invariably on the weekend it'll rain and I can completely miss seeing some species and varieties with open flower some years.  Now that I am home and unemployed, I get to see them (and photograph them) everyday. :D


Submitted by Boland on Tue, 03/23/2010 - 17:41

I think MY Gypsy Girls are Fuscotinctus as well!  I went back and checked my older pictures and Gypsy Girl has purple stripes with just slight feathering that does not reach to the edge of the sepals.  On Fuscotinctus the feathery is more pronounced and does reach the edge...you can see that on both Tronds and mine.

Mark, pics I've seen of kosaninii show yellow at the base of the tepals on the outside and inside.  Your base looks darker, but as you say, there is variation.

Mark, was that crocus chrysanthus article by Tomas Huber?  I have a copy of photo plates taken by him in an article he wrote but be darned, if I know the original source.  I use his pictures all the time to try and ID my chrysanthus and tommies.

Actually, he (Mr. Huber) made two of them, each is a multi-page thread... a wonderfully useful work.  I'll refind it and provide links for all; I'm off to watch some TV to unwind for a bit  8)

Thanks both of you. I can remember planting cultivars of etruscus and chrysanthus and others too. Regarding 'Ruby Giant' I know I have some of them as well, but I thought they had another deeper color. I have several of  "big" blues (or what you will call those colors) of different hues. I have several small ones (Crocus tommasinianus?) too of colors from white, cream, yellow and blue. Those seem to interbreed. I have planted them in my lawn not bothering to separate cultivars.

Mostly common garden hybrids and seedlings, this was the sight today when I arrived home! I tried to take some close ups but my old camera but the autofocus tricks me. The cereals are residues from bird-feeding.

Wow Trond, that's a lot of Crocus!  :o :o  Looks like spring is finally happening for you.  What's the identity of your Crocus 12, it's a real beauty with those violet purple goblets and white interior.  Did you plant all these, or are they self seeding?  On the Scottish Rock Garden Society forum, there are a few members that have created bulb lawns, full of crocus, snowdrops, and other spring ephemerals, for amazing spring displays.

The precious few I had open are now buried under 4" of snow  :-[


Submitted by Hoy on Sat, 03/27/2010 - 15:36

Sorry, Mark, I can't help you with a cultivar name. I know I have planted both siberii and biflorus in that area. Most of the plants are seedlings (of vernus and tomassinianus and different hybrids). My lawn is a bulb lawn. I can hardly put down my feet anyplace. And you know, the spring here is a long story starting in February and ending in late May!

Todd, I am not jealous on you! Though we can have snowfall as late as April it has not been common for many years now.


Submitted by Lori S. on Sat, 03/27/2010 - 19:57

Snow only as late as April?  I hate to admit it but it's the norm here to have a week or 10 days of dreadful weather in April (which is the usual determinant of whether our pear trees will produce fruit or not) with snow and overnight lows as extreme  as -15 deg C... wonder what this year will bring? 
Still, I have to say that it's in the snow in June that really hurts!  (Thankfully, it only happens every few years!)

Actually, it's a bit spooky that we have not had our usual huge dump of snow in March yet... and only a few days left to go... (I have this ominous feeling that we are tempting fate...  :o)

Crocus season is starting here with a few individuals, earlier than we've seen it before... The big clumps will be a while yet.

Nice start to the Crocus season Lori, they are such cheerful flowers, one never has enough of them.  May you be spared further winter-like weather misery.  It went down to 18 F (-9 C) last night, and this morning I actually touched and squeezed the blooms on crocus, and they were hard as rocks!  Later on today, it warmed up above freezing, the flowers were fine.  A dry freeze seems less damaging than a late wet wintery-mix sort of freeze.

Isn't it amazing what plants, and even flowers, can take in terms of temperature extremes?

Three forms of Crocus malyi, my last crocus hurrah!

Observing Crocus species over the years, I believe C. malyi to be one of the very best for growing outdoors, providing a bold display of pristine white blooms that are more waetherproof than many.  This message compares C. malyi 'Sveti Roc', C. malyi 'Ballerina', and an unnamed form of C. malyi that I received from Jane McGary that looks more like the 'Ballerina' selection.

Cultivar        flower width      tube height  scent                    distinguishing characteristics
=====================================================================
'Sveti Roc'    5.0 cm              2-3 cm        none                    short stature, full rounded flowers, pure white
'Ballerina'      6.5 cm              4 cm          light melon scent    tall stature, brownish tube tops, long petals, outer petals with fine
                                                                                      purple line on outer tips.
McGary form  7-8 cm            5 cm          light melon scent    tallest stature, brownish tube tops, long petals, no purple lines

Photos of each are uploaded.  In the photo of the Jane McGary form, flowering size seedlings are there, and note one on the lower rigaht with rounder petals.

What an amazing collection of crocus you have, Mark!!


Submitted by Hoy on Sun, 03/28/2010 - 10:14

I have never considered planting malyi but now I see I have to change my mind!


Submitted by Boland on Sun, 03/28/2010 - 15:52

Never heard of malyi...but then we have limited access locally to funky crocus species.

All of mine are now under 4-6" of fresh snow.....just as well with the temp down to -6 C and 50 km winds!  Guess it will be another week before this latest snow melts.


Submitted by Lori S. on Sun, 03/28/2010 - 23:43

We're doing a little better than that here, with crocus blooming a week or more early...   No unusual species, but a joy for us to see, nonetheless!  :) 


Submitted by Hoy on Mon, 03/29/2010 - 08:44

Both the blue and yellow seem to differ from any colors I have. Have tried several cultivars to have early ones and different colors.


Submitted by Boland on Fri, 04/02/2010 - 13:30

Well it hit 16 C today and the crocus responded!  Here are some selections of C. tommasinianus...Lilac Beauty, Barr's Purple and Ruby Giant.  The Barr's Purple self-seeded in the lawn.


Submitted by Boland on Fri, 04/02/2010 - 13:31

First C. chrysanthus selection...Saturnus.


Submitted by Hoy on Fri, 04/02/2010 - 23:45

There you see, you will catch me up, Todd. Don't think we will have 16C for a while!
The lawn seems to be green too.
The tommasinianus selections look like mine which I have no name of.


Submitted by Boland on Sat, 04/03/2010 - 15:25

More open today...C. X hybridus 'Jeanne D'Arc', C. etruscus, C. minimus and C. chrysanthus 'Advance'


Submitted by Mark McD on Sat, 04/03/2010 - 19:43

Todd, I liked the Lilac Beauty, one I'm not familiar with, it is a beauty.  Always like seeing C. etruscus, such a classic shape and coloration on this one.  I have tried C. minimus, purchased at Home Depot in discount bonus-sized packages (Home Depot; a large "big box" home improvement chain for those unfamiliar with it), but they are not true to name, so I'm glad to see your photo which looks like the real thing.


Submitted by Boland on Sun, 04/04/2010 - 13:32

I blundered on the ID of C. minimus...it is actually C. corsicus.  Here it is with the flower closed.


Submitted by Boland on Mon, 04/12/2010 - 17:28

Crocus still going strong...the C. sieberi are now out..they are among the last to bloom.  Meanwhile, on the north side of the house, the tommies are just sprouting!

Below is Tricolor, Violet Queen and the beautiful Hubert Edelstein


Submitted by Hoy on Tue, 04/13/2010 - 00:57

The Crocuses (or Croci??) are finished here except a few stragglers. Edelstein is new to me. Looks nice.


Submitted by Lori S. on Fri, 04/16/2010 - 09:21

Despite a very early start, the crocus season is really just getting going here!
Having said that, the Crocus sieberi 'Tricolor' are done now... accelerated by the snow.


Submitted by Lori S. on Sun, 04/18/2010 - 19:38

Wait!  I'm not ready to give up on crocus yet!  ;D
1) Crocus chrysanthus 'Advance'
2 - 7) Various C. chrysanthus, tomassinianus(?), vernus...
8, 9, 10)  These two common C. vernus types seem to have got together to make this intermediate form (last photo)... unless I'm forgetting what all I planted a decade ago.   (Who me???  ;D)


Submitted by Hoy on Sun, 04/18/2010 - 23:47

I am already longing for next spring! My crocuses are all leaves now.


Submitted by Boland on Mon, 04/19/2010 - 16:30

Great crocus show Lori!  Mine are all tightly closed with all the rain, drizzle and fog.  I hope to get a pic of C. sieberi 'Hubert Edelstein' with open flowers but it doesn't seem likely.

Thanks Ian!  I have downloaded his pics as a future reference.  Our weather has been so wet and cold this past 10 days that most chrysanthus simply rotted before they ever opened properly.
