As a certified horticulturist for about 50 years, I prefer the botanical names as well. To someone grounded in Latin and some Greek, it tells you so much more about the plant (or animal) than common names do. As a for instance. alba lineatus literally means white lined. It is a brilliant system and universal as you have stated, but as to "anyone can understand you", well, that will never happen.I prefer the scientific names, common names can be very confusing, but the scientific name its universal and anyone can understand you
I know that many people who viewed that particular post, probably most people, viewed it as Ice Plant rather than Delosperma.
But I do agree that common names can be both confusing and misleading.
