Skylark, I usually just start with the cultivar name or even a part of it if I'm not certain of the spelling. In your example, I searched for 'pick me pink' and your euphorbia was first in the list, followed by some other plants with similar names. I only use the latin name as a search if I am flumoxed otherwise, as often the spelling gets tweaked by the powers-that-be (not those on ATP but whoever makes decisions in the botanical world). I also find it rather interesting to see what other plants might share the cultivar name.
