LONGEVITY OF THE SEED. There is but little information as to the length of time that the seed of the Easter lily will remain viable after it is harvested. Ex- [)erience has shown that if planted as soon as it is gathered it takes about twice as long to germinate as when held and planted G months later. Perfect germination has occurred when the seed was 18 months old. This shows that perfect results may be expected from seed held over to the second year. Whether seed can be safely held hunger is not known. All the seed worked with in tliese investiga- tions was stored in i)aper sacks in the packing shed of an ordinary irreenhouse. 11.
