Bridal Silk is a Shirley poppy. Shirley poppies thrive in cool temperatures and must be sown when the soil is still cold. ‘Bridal Silk’ has glistening pure-white chalice-shaped flowers in glorious bloom during early summer, new flowers opening every morning as the old flowers shed their petals. These plants prefer evenly moist soil but can tolerate drought. About an inch of water per week is more than sufficient once they are established. Plant height 45-60 cm.
