Nodding white flowers, usually 2–3 per stem, with narrow petals and a delicate cup. They have a light, feathery quality. Thalia is excellent for massing at the edge of woods or in a shrub border. Also grows well in the Deep South.
Thalia is almost 100 years old, but it still has a verve that makes you fall in love with it over and over. It has proved to be an excellent perennializer, and with its bright white color, Thalia creates a gorgeous display every spring. It combines very nicely with grape hyacinths.

To get the most from daffodils, follow these 4 basic rules:
- Plant them where they will get at least 6 hours of direct sunlight, even after they have finished flowering and the trees have leafed out. Daffodils need lots of sun after they bloom to produce next year’s flowers.
- Plant them in soil that drains well. Avoid areas where water stands after a rainstorm.
- Fertilize very lightly with a low-nitrogen fertilizer, preferably organic, just as the shoots emerge from the ground in early spring.
- After daffodils flower, wait at least 8 weeks—until the leaves turn yellow — before cutting them. Never tie or braid daffodil foliage. This year’s leaves = next year’s flowers.
If you want to naturalize daffodils (i.e., plant them so that they look as though they had sprung up on their own), we suggest that you set them out in drifts (not in blocks or lines) and that you space the bulbs farther apart than recommended on the bag label (to allow room for the clumps to increase in size). If you want to naturalize daffodils in a grassy area, you must wait to mow until their foliage has turned yellow, which means allowing the grass to grow very tall.
Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.
Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.
