I shouldn't, but I do get a little aggravated when someone has a problem with a plant and I ask what I think is a pretty simple, straight-forward question -- what's the name of the plant?
I think that if you care about the plants in your realm, you should have the wherewithall to find out what you have, what its requirements are, and then proceed to give it the care it needs. Of course, if you don't care, then just skip to the next post.
I had a visitor drop by the other day and ask 'Why isn't my lilac blooming?'. I ran down the list of the reasons why I thought. He said 'Just go out and take a look at it'. So I did.
He didn't have a lilac on site.
Not to ramble on, but I do think that knowing a scientific name every once in a while is not plant snobbery. It just shows you've taken the time to find out and that you care. If I hear 'Hy-geranium' one more time, I think I'll have to go prune something.....
