One of our favorite white daffodil flowers is 'Thalia', a late white daffodil that means that spring is wrapping up and we're heading into summer. This white on white star shaped daffodil brings a unique shape and interest to your daffodil garden. You will find multiple fragrant blooms on each stem. This makes a great cut flower for inside your home. Narcissus triandrus 'Thalia' conditions are similar to most daffodils: full winter sun, well drained soil, avoid standing water, and avoiding too much competition.
Plant the bulbs about 2-3 times the size of the bulb (so if the bulb is 1 inch long, plant it 2-3 inches deep). If you are farther north and get very cold during the winter, you may want to plant it about 4-6 inches deep. Space the holes about 3-6 inches apart, and for a more natural looking display, consider planting 2-3 bulbs in each hole.
