Thanks Jim W. for your posting. Hyacinthus cvs. and species etc. are currently my favorite bulb to collect and grow. I, too, grow Hyacinthus litwinowii, orientalis chinophilus, and transcaspicus. The first two species were Archibald offerings, H. transcaspicus came from a private collector. I'm hoping for some bloom this season. Lately, a number of historical hybrids have become available, originating from the primo supplier, Edward Shipper, in the UK. Old House Gardens of Michigan offers some of these hybrids from Mr. Shipper, but another supplier In N.J. also has an ample offering of hybrids, as well as another commercial grower in the Netherlands. I propagate from bulbils formed by cleaning the basal plate, and slicing the bottom of the bulb into 6 sections, by making 3 cuts through the basal plate, but leaving the bulb intact at the top of the bulb. It forms multiple bulblets where the cuts have been made. I remove the bulbils, and plant them shallowly in a pan of sandy compost and grow them on. The Holland Bulb Council recommends regular feeding, once in the Fall, once in early Spring, and yet again after flowering. I use Holland Bulb Booster, and have had great results. It's a 9-9-6 analysis, which, apparently is what the bulbs want to keep them up to size.
