Hymenocallis 2013

[ThomasB]

Hope this Beauty will flower for you, Fermi! 

H. 'Sulphur Queen' is not a difficult bulb here. Actually it's growing together with several bulbs of H. x festalis in a large pot on my balcony during summer. I'm cutting the leaves once frost is predicted, place the whole pot in a cool cellar and keep it dry till next spring. The plants are heavy feeders and drinkers.

Thomas, leaves must not be cut if still green. If need be, the plants must be taken indoors to let nutrients in the foliage to migrate and fatten the bulb.

All said, Jim's comments and images refer to proper Hymenocallis. 'Festalis', 'Zwanenburg', 'Festalis', are all Ismenes. Two different genera for two groups of different looking plants. This said to avoid the confusion concerning these plants.
