Plant details

A plant you are more likely to smell than see the flowers are tucked down among the slender leaves and, though pretty, are modest. Plant three or five plants close together, in a group, in a warm sheltered sunny spot beside a path or garden seat where you are likely to appreciate the ripe greengage perfume. Plant them close to other flowers in bloom at the same time, such as dwarf or intermediate bearded iris, tulips, or rock plants. Iris graminea is an undemanding plant that does not spread, and rarely needs lifting and dividing. The Royal Horticultural Society has given it its prestigious Award of Garden Merit (AGM).
