That most rare of flower colors, pure cobalt blue, is found in spades here. Cultivated since the late 17th century, it has starry rings colored white and yellow, etched on a deep blue trumpet-shaped flower. A low growing gem for the front of the garden, pretty with sweet alyssum and Chinese-forget-me-not 'Chill Out'.
Very bright, royal blue, morning glory flowers with a white and yellow throat. Blooms prolifically during Summer on a neat, compact mound, 1' tall by 2' wide. Looks great with sweet Allysum. Excellent container plant. Always a popular plant!
