Rod Lysne of
Northern Grown Perennials in Wisconsin crossed
two unnamed seedlings
to create this large size cultivar which he registered in 2006.
It is projected to grow into a giant size hosta around 40 inches in height and 9
feet in width. The leaves are broadly ovate, slightly corrugated
with thick substance. In July, it bears lavender flowers on
scapes nearly 4 feet tall.
The 2021 registration materials
for H. 'Standing
Room Only' say that it is a "reciprocal sibling" of this cultivar.
Reciprocal siblings occur when the same two plants are used for two different
crosses. In one, Hosta A is used as the pod parent and Hosta B is the pollen
parent. In the second cross, A is the pollen parent and B is the pod parent. The
parents of both cultivars are two unnamed seedlings originated by
and Cynthia Tompkins in their breeding program.
