Hosta June Fever ® sport of Hosta ‘June’ comes up in spring with a bright yellow (becomes orangish) leaf centre surrounded by a thin blue-green border. There is no grayish wax on the leaves so the finish is shiny. The colour holds until about the end of June and then begins to darken slowly until it becomes chartreuse.
