Before 1990 the use of curate indicated a parish priest who was charged with the care of souls. A later form of the word is curator, indicating someone who "oversees or manages a place" such as a museum or a zoo. This is often the person who chooses the art or animals.
I could say that I carefully curated the fabrics for the quilt I finally completed today. However, I used a variety of scraps - pieces of Tim's dress shirts, remnants from sewing children's clothing, etc, so that can hardly be called curated.
The use of the word is increasing and causing some discomfort to English purists. I know that I find it somewhat pretentious, and there is nothing wrong with just saying "chosen", as in, "She has a carefully chosen collection of dahlias."
My own dahlia collection is eclectic and that little pompom dahlia at the top is a tiny one, just 1 1/2 inches across. It has been in a pot, and I find they do better in the ground, so that's where it will go next year.
