The plant is an unusual example of very strong pebbling, very stable streaking and is structurally upright with rounded leaves. Together it makes quite a specimen hosta which has been a show stopper plant in my garden. It continues Bill and Eleanor's breeding line through their 'Sand Pebbles' cultivar which has siebodiana in its background. 'Halley's Comet' is a result of a cross of 'Sand Pebbles' as pod parent back to sieboldiana as the pollen donor."
