Hosta 'Blue Umbrellas'
 

This is another of the many hostas originated by Florence Shaw of Massachusetts and registered by Paul Aden of New York in 1978. It is a giant size (33 inches high by 72 inches wide) cultivar which has slightly blue-green leaves that are cordate, convexly cupped and rugose. Very pale lavender, bell-shaped flowers are borne on 42 inch tall scapes from June into July. It is registered as a  hybrid of H. 'Tokudama' × H. 'Elegans'.

From the Field Guide to Hostas by Mark Zilis (2014), "It certainly is not a hybrid of 'Tokudama' and 'Elegans' since a cross of that nature would likely be bluer, smaller, and bear near-white flowers...A cross between 'Elegans' and 'Green Wedge' or another 'Elatior' type would account for the shiny, dark green character, convexly cupped foliage, and flowering habits..."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Leaves, which soon turn shiny dark green, droop downward at the edges, giving an umbrella-like appearance."
