can I grow a large Yucca plant in zone 7a
I have built a six acre garden fully landscaped and in my sunken Italian garden require tall stately plants that flower. I am unconcerned about sharp leaves but I am about winters here that sometimes go down to 20 C below. The snow helps protect plants but for two months we do not venture into the estate, as it is too cold.

Much will depend on the variety of Yucca that you chosen.
There are some varieties of Yucca that are hardy down to zone 3.
