Gardening is always a mystery to me. I plant with no estimation of survival rates. Last fall, I planted a couple hundred new bulbs and a couple dozen pansies. Bulbs are winter hardy, and they bloom before my tree leaves, so they seem a good choice. However, the fall was very warm, and many of them sprouted leaves, so I wasn't sure if they'd bloom this year.
Of the 100 anemones I planted, three reds have bloomed. None of the whites.
