I really like these delicate flowers. However, I bought many bundles, as I needed to fill up a large pot. They are tiny flowers. You will need more than you assume. But I think the "look" is worth buying extra.

Ex Input:
Well designed, easy to use. Great value for the money. I'm working with a nice mild mannered dog who likes to wander to the neighbor's house and hang out by the road. I stopped him at the boundary line the very first time with a few beeps and called him back to me. No negative reaction at all. This is going to improve life for both of us.
