Not for establishing a brand. I would use it to rank for "donate flowers" and related flower donating keywords. Throw up some related articles and advertisements with flower affiliate programs. That's what I would do.
You can sell flowers as an affiliate to many of the large flower vendors.
Improper english? Uncommon phrase? Did you research the keywords? Obviously not. "donate flowers" is worth targeting. I'm not going to educate you on the flower industry, but donating flowers is a common practice...
