Now all I need is a $40 million biology laboratory and I will be able to label my narcissi! The N. bulbocodium forms are continuing to flower through the very long period during which different ones appear, and I am not even going to attempt to sort them out, but will merely describe and photograph them for the database. If they appear on my list and originate from a population new to other growers, perhaps they will be of interest for genetic variation, or to trial in gardens where not all forms succeed.
