Cultivars/Varieties

'Arthur Burkwood' - This is one of the original two seedling to resulted from the hybrid cross. It grows to about 3' tall.

'Briggs Moonlight' - This is a sport from 'Somerset' in which the majority of the center part of the leaf is yellow and the edge is green. It needs some shade and lacks the vigor of other variegated cultivars with a greater percentage of green tissue.

'Carol Mackie' - This form has creamy white margins on the leaves that contrast nicely with the dark green central leaf portions. It is a popular cultivar with a nice variegation pattern and it grows vigorously.

'Silveredge' -This cultivar has leaves edged with white and pink flowers.

'Somerset' - A plant that grows to about 4' tall, this is one of the original two seedlings from the hybrid cross. It is a a vigorous cultivar that grows wider than tall.
