"High geraniums are shrubs. You remember momma had blue ones growin' in the shade out by the shed in the back yard".
"Low geraniums are red and orange and you gotta bring 'em in fo' the winter".
She may have had the names confused, but at least she knew where they should be grown. My own "high geraniums" are just coming into full bloom this week.
Hydrangea macrophylla var. serrata 'Kiyosumi'
Hydrangea macrophylla 'Mariesii Variegata'
The next four are two different varieties from the Halo Series, but unfortunately I did not know which two they were when I planted them. All of the varieties in this series have petals with a white "halo".
Hydrangea macrophylla 'Glory Blue'
I did not plant this one, it just sort of appeared and it's name is unknown.
