Miss Carrie Brown of Dayton, Ohio, was very successful in blooming Lily of the Valley last Winter, and in response to a request from the Montgomery Co. Horticultural Society, gave the following note as to their treatment:
"It is necessary to leave them in the ground until after a hard freeze. It may perhaps do to transplant the bulbs in the Fall to pots or boxes, and let them remain outdoors to freeze. In selecting the bulbs take those that have rounding tops instead of the pointed ones. Put them in a very warm place, and the light is not necessary for them until they are well started, at least an inch high. Then give them light, but do not put them too near the glass, as they often blight if the sun is too hot upon them".
