The only rocks I know are the kind in jewelry. I'm pretty good with those.
I'm starting to learn the botanical names of plants simply because - after some 20 yrs, sheesh - I have so many plants some are the same family but diff members. Like 4 campanulas. Botanical is the easier way to keep them straight.
Speaking of those, I finally snagged Canterbury bells, Campanula medium.
It's supposed to get what, over 2' tall. It's about 3 inches and blooming. Now that's funny.
The flowers are big as the plant.
