Wow those hostas are awesome. I have the same thought with the geraniums. I really like them and am going to see if mine make it through the summer this year and how long I can keep it going. The Allium is pretty too so cool that it is from your time abroad.
Geraniums are a really hearty flower. We bring them into the garage in October/November and they basically go dormant for the winter. Then we bring them back out in April/May. But we always lose a few each year.
She actually bought the Allium and some tulips while living in Canada. They were shipped from the Netherlands. But still reminds us of being in Europe.
