Galanthus nivalis often pushes bulbs to the surface, and I've even seen Narcissus cultivars do the same. The physical mechanism seems to be overly exuberant production of offsets until crowding forces some onto the surface. The adaptive value is that doing so facilitates asexual reproduction. Commercial bulbs of /Iris danfordiae/ are notorious for breaking up into "rice grains" unless planted very deeply. My guess is that this too is a strategy for facilitating asexual reproduction when the bulbs are near the soil surface. -- RFW "It's MY computer, Mr Gates.

You are colder than us here in SE Pennsylvania, but not so much more that I'd expect that to happen. Cold hardiness is very much influenced by drainage - was the ground these tubers were in at all soggy? Freezing and thawing in less than perfectly well-drained ground could cause you to lose plants that would be hardy with perfect drainage in a garden a zone colder. On our S facing perfectly drained hillside I have a number of hederifolium that are 25-50% exposed to the air - they look like flying saucers that have crashed into the slope and stuck half-way in. They are up to 8" diameter - but they come through the winters just fine. I'd try to optimize the situation and drainage - and then you can certainly plant deeper as well if you want, as long as whatever is on top drains perfectly then the flowers and leaves will find a way through. You could put up to 6" of pure gravel on top of them without issue - but don't create a sump for water to gather on top of the tubers. Good luck! J.

More is okay, less is bad. Hederifolium puts out roots from the top and sides of the tuber, unlike coum and the like which have roots on the bottom surface only. Don't worry, the foliage and flowers will make it up through most anything. I've rescued tubers from seeds that germinated six inches deep in a pot, and tiny filament-like leaves somehow make it to the surface. I have planted Cyclamen hederifolum all over my garden, and they appear to be happy in some spots, and a disaster in others. The best locations seem to be on a north facing slope under a japanese maple, and on top of the septic tank (a little extra warmth?). The ants seem to find good locations, too, and volunteers are thriving in some very unlikely spots. In addition to hed, coum, cilicium, and purparascens seem to be the best for naturalizing in this way, and love coarse gravel as a seed bed. It always pains me to run the lawnmower over the coums in the lawn, but the ants drag them out there, too. One final tip is to try to find a spot that doesn't get any direct sun in the winter. Sunlight makes the normal freeze/thaw cycles in NE even worse. Good luck with your planting. My own goal is to get pseudibericum going outside one of these days. It was happy in an unheated cold frame last winter, so should be worth a try. --Roy NW of Boston Snow cover? Hah! Unreliable at best...

The time is 7:45pm, place is San Francisco County Fair Building (Hall of Flowers), 9th Avenue & Lincoln way, San Francisco, CA. The talk is preceded by a stroll around Strybing Arboretum and Botanical Gardens at 4:00pm, then dinner at a nearby restaurant. You don't have to be a member to attend. I will be taking a selection of bulbs for sale at prices reduced from the catalogue, and, hopefully, some that are not presently listed. There is a drawing, to which I am contributing a small Pamianthe peruviana. I hope some members can make it to the meeting. The walk around the Arboretum and the dinner gives everyone an opportunity to meet.

It started as a single seedling from the Archibalds highest altitude collection after I dumped the two year old un-germinated pot. The tuber was quarter-sized after 3 years and is now planted in the garden here in TN. Purpurascens was by far the best in Kansas, and seems content here so far also. Hederifolium was always iffy in Kansas living about 2 years on average. Coum I got to bloom once, but always died in early spring or summer.

Much depends on how long you have for exploring. If you could get to the flower auction in Aalsmeer that would be an interesting experience. Funnily enough I never went to an actual auction while I lived in Holland, but used to love visiting the wholesale florists and plant-sellers who occupy part of the cavernous auction building - see http://www.cultra.nl/. There you get a concentrated experience of the Dutch horticultural industry as they sell something of everything that passes through the auction to smaller traders/florists etc who don't need 10,000 roses all at once. You can just walk in and prowl about but you need an account to buy anything. What they offer of course depends on season but is always amazing. I once was able to buy bunches (50 in each) of Oncocyclus irises, imported from Israel. In Amsterdam itself the floating flower market is interesting, even if touristy, & there are a couple of bulb sellers. To those accustomed to the dullness of an English or American florist's offerings a visit to even a local Dutch florist's shop is a revelation. For a non plant-related activity Amsterdam is of course full of cultural interest, which could be combined with a horticultural theme. You could go to the Rijksmuseum to study flowers in old flower pieces - not to mention the Rembrandts etc. There are some surprising plant images in the Van Gogh Museum too. For food I would recommend an Indonesian meal - the Dutch East Indies connection is quite strong. I used to go to Sampurna, an Indonesian restaurant (http://www.sampurna.com/) by the flower market and have a rijsttafel - a selection of all sorts of small dishes of delicious things.

For more specialised visits go to Lisse and see the HOBAHO or CNB bulbtrade center, there are always displays of flowers and of course million of bulbs (especially on a Monday).

I have always seen the flower and leaf stems go out horizontally for some distance before heading for the surface. In pots, I always get a ring of leaves and flowers around the the edge. In the ground, the effect is like a wreath, with a hole in the middle. Later season leaves sometimes fill this in a bit. On the other hand, C. graecum is one of the types that grows up, not out. In this species, formation of a trunk is to be expected. I have some elderly tubers, nearly 20 years old, with trunks close to three inches long. The root structure on graecum is radically different from hederifolum, with big, thick, possibly contractile roots only on the bottom of the tuber. My biggest difficulty in growing them is to find a pot that is deep enough to handle the tuber (~4" diameter), the floral trunks as described, and six inch long roots that resemble pencils. Usually the roots wind up getting folded over. I recall an article in the Cyclamen Journal that described graecums found in nature with trunks over ten inches long. All perfectly normal! --Roy NW of Boston ----- Original Message ---- Roy, Allthough I am in a much milder climat (we get frost down to -8? 18F) I never put more then 2-3 cm (1") of soil on it.
