Everyone once and a while a milestone is reached in the life of a gardener. I purchased seed of this Narcissus from Chiltern's seeds in 1998 and it flowered today for the first time. I was grown completely under HID lights. Note that its flowering time is identical to when mine has flowered although I have not adjusted the light level or length of day to coincide with its normal out door cycle. The bulb is native to Central Portugal and as the name implies it grows in calcareous soil, due to the presence of limestone but Henning Christiansen has shown the pockets of soil it grows in have been found to be very acid around pH 5.9 http://pacificbulbsociety.org/pbswiki/files/… Arnold New Jersey cold wet with snow on the way.
