I find myself in the odd situation of knowing some flower names in japanese but not remembering or never knowing them in English. Why? you might ask. Because they are all around me, something thats a daytoday experience and some plants werent in my part of america. Not so with the above plant. My mom had some in her garden (though i do seem to remember them blooming later than now?) but i couldnt remember their english name. their japanese is あじさい (i didnt know the kanji which is apparently 紫陽花) so i looked it up and it felt right. so "hydrangea" is here so i remember this flowers name.
