how to make an umbrella from a plant

from my friend barry at sunshine farm & garden comes this wonderful shade loving 'american umbrella leaf' plant, Diphylleia cymosa. reminds me of a may apple, and rightfully so as they are related, but barry says the umbrella leaf is like a may apple on steroids, though! i love the idea that woodland creatures and birds take refuge under the umbrella-like leaves during rainstorms. the plant sounds easy to grow and propagate as the umbrella leaf is native to several southeastern states and apparently is hardy in all 50
(even hawaii?!): wow!
