Experienced an unusual situation occasioned by this daffodil yesterday. Plant was one of the last of a bunch of forced daffodils over the winter. Bulbs produced good sized plants that were flopping over. When I brought them upstairs to enjoy them, I couldn't find a suitable place to put them. They were so flopped that the only way to enjoy them was by looking up at them, so I decided to put them on top of the refrigerator. They looked ok there (pic of this in DB). Later, when I was getting some refreshment from refrigerator, the whole pot of bulbs jumped down from up there, sailing down and grazing my head (like ruffing my hair) before landing upright on the kitchen floor. I said wow! to myself. I cut the blooms off and stuck them in a vase (pic of this in DB).

This entry has been described as 'gargantuan'. Considered an excellent garden plant and companion to other bulbs.

The International Daffodil Register & Classified List lists two cultivars so named. The other one is a registered Division 1 Trumpet daffodil w/ white petals and a soft yellow corona first flowering before 1934.
