Hi Leucojumfriends , I enjoy this discussion about this genus and here is my report from the species that I grow : L. aestivum - from this species I know only "Gravetye Giant " - this plants grows without problems in my borders . L.aestivum v. pulchellum : This plants I have collect on the balearic island of Mallorca - I have found these plants near the sea on a river - they grow good free in my garden ( with temperatures until - 15 C ) L. autumnale : this plants grow on sunny borders free in my garden . L . longifolium : I have sown this plants , grows in pots in my greenhouse L.nicaense : this plants grows also free in my garden - also in sunny borders L. roseum : this species grows also without problems free in my garden , in this year ( September ) by my travel in Corsica and I have found 3 populations in flower - the grow in rock pockets ( Porphyr ) or in open stony maccia area , together with Scilla autumnale, on a high of 80 - 130 m , the soil was acid . L. spec. from one of the ionic islands - collected from a friend - I believe this is L. valentinum - after my informations this species grows in Spain and on this Greece islands , I grow this plants in a pot : in winter in my greenhouse and in summer in my bulbframe . L. tingitianum : this plants ( received from Archibald ) I grow this plants in pots in my greenhouse - I have these species since August of this year . L. trichophyllum : I have received this plants from a friend , he has collected this plants in Spain , I grow also the "pink" form , but until now I have not any expieriences , they grow in pots in my greenhouse . L. vernum : This species grows here in my area natural on shade or semishade woods in wet condition ( together sometime with Galanthus nivalis and Primula ) the grows near rivers or lakes , I know some different populations from 200 m altitude until 1000m , they grow in all kind of soil , in this location with the 1000 m in the french mountains there grow L. vernum together with Narcissus pseudonarcissus , Daphne spec. , Lilium martagon. I have since many years this plants in my garden and it is the same like all the other observations - they grow really slow - the multiplication is not so good , maybe my garden is a bit to dry , they grows by me in semishade between my Helleborus . L. vernum v. carpathicum , I have bougth this species before some years , but I'm a bit dissapoited - the blotches are not really yellow - maybe one reason is my calcy soil . Thats all - I hope to find the other species that I search to find one day . This plants are a really nice addition to my Galanthus , Eranthis, Anemones and all the other bulbplants . With best wishes Hans Southwest- Germany
