Narcissus 'Thalia'

Narcissus 'Thalia'

An elegant triandrus daffodil bearing 2-3 nodding pure white flowers per stem in April. The swept-back petals and graceful habit make it one of the most refined daffodils. Excellent for white-themed borders and naturalistic planting. Lightly fragrant. Pairs beautifully with blue muscari and forget-me-nots in UK gardens.
