In Eldorado you can estimate when it's possible to plant hemerocallis by using the USDA zone info.

Since hemerocallis do well in moderate cold you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

The last month that you can plant hemerocallis and expect a good harvest is probably September. Any later than that and your hemerocallis may not have a chance to fully mature. If you are starting your hemerocallis indoors then you might be able to get away with starting them a little bit earlier.
