Thanks to all for the responses here. Like many I assumed one bulb would produce one spike annually, but I have at least 2x as many spikes visible this year as last and many more small shoots. I'll let you all know what actually blooms as they progress. They have not been subject to any damage to induce this sudden multiplication. Don't think I accidentally split any while digging. I think it is a combination of maturation and a mild winter, perhaps. They are growing in my basic soil-glacial fine grain loess clay over limestone. Alkaline and water retentive. These are all named cvs and I haven't looked at the labels in a while, but I think one is 'Innocence', but don't quote me. I also have some mulitflorum types in another part of the garden that have multiplied very slowly over a longer period of time. They produce a few small spikes per bulbs. I am surprised at how few are shown on the wiki http://pacificbulbsociety.org/pbswiki/index.php/… , but this does depend on the generosity of members so get pix of those species available. I's love to see more of these wild hyacinths. I hope Jane and Reichjke can bring out their cameras to share some pix. Bloom season still isn't quite here and not all bulbs have even sprouted so there's more surprises to go. Always something new in the garden. Best Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
