Here is a Romulea from Cedar forest in Morocco : which species could it be ? "Only" R. bulbocodium ? It is just finishing to flower ; the plant is autogame and do not have vegetative multiplication...

Thank you Alberto.

I am glad you confirm my identifications.
As you have probably noticed only a few people grow this genus, and there isn't any 'Guru' or a good reference  to consult and so i study this genus from the little material written and by growing and observing them in my field trips in the Mediterranean.

Thanks for the encouragement

Hi Oron:
   
            Not that Eurasian romuleas are easy to grow weeds but I suspect that there is even less interest from the impossibility of identifying them with any certainty. Moreover, fancy names, particularly of those from N. Africa, complicate things further.

           I will write more later.

Regards

Francois,
It is R. bulbocodium and a nice one since all its center is yellow.
in most forms the yellow stays only inside the throat.
This phenomenon of bluish -purple buds to then transform to a white flower is typical to R. bulbocodium and R. nivalis.
thanx for showing it.

Thanks Oron (Fred is Bulbissime, a friend of mine ; I'm François, or Bio as it is said on french forum  ;) ).

Here is after a romulea from Podgorica in Montenegro : vegetative multiplication and gitonogamy (no autogamy possible) ; as I saw in the post, may I name her R. bulbocodium var. leichtliniana ? Flowering time is march in my garden.

Moreover, how do you differentiate R. bulbocodium and R. nivalis ? I have the last species from Paul Christian but I found it very similar to the first one...

Finally, only for the pleasure, a pict of R. hirta : interestingly, it is the only bulb which survive from a lot bought some years ago, actually the less tender : I sown its seeds and seedlings are also frost resistants  :D !

Pardon Francois, vous aves raezon,

Yes, you can name the first R. bulbocodium var. leichtliniana.

It is quite hard to distinguish R. nivalis from R. bulb. out of its natural habitat.

Romulea nivalis grow at high altitudes usually above 1500m, and bloom just days after snow melts, around mid March.
It has much shorter leaves, color of the flower is basically white with yellow throat often veind purple with the upper part of the petal purplish blue.
But the best is to check the bulb: R. nivalis bulb tunic is membraneus  while R. bulbocodium bulb tunic is hard dark shell like , similar to Colchicum.

Hello,
Apart from Tropaeolum I'm starting some new things : romulea, moraea and leucocoryne. I've sown some romulea which I've got through the seed exchange last year and much to my surprise I had 2 flowers ( R. "bulbocodium "I think ... ). So I decided to try others. Are they all that quick to flower from seed? Are they all  hardy? ( I'm from FRANCE ). By the way it's an interesting topic  even for beginners . Thanks for all your nice photos.

The bulk of species in the genus are winter growing South Africans, the most striking ones are in this group. They come from frost free areas, enjoy full sun and many inhabit spots that become seasonal pools at flowering time. Of these R. hantamensis is hardy. Those from the mountains of South Africa and Africa, summer growers, are hardy in most cases.

Those from an Eurasian origin are hardy.

The most widespread species in Eurasia is R. bulbocodium, in which the style clearly overtop the anthers, and the bracteole, almost completely paper like, reddish or brownish. The floral tube, 4-8 mm. long, the bract, green and 1-2 cm. long. If the stigma branches are well exserted beyond the anthers the first guess is bulbocodium. Color or color combinations in the flower are not relevant as this species is variable according to the region.

Romulea linaresii ssp graeca is in full bloom today,
It has a tiny flower with dark throat [not yellow].
