Is this a lily or bromeliad?
I think it is Hippeastrum. Hippeastrum is a genus in the family Amaryllidaceae (subfamily Amaryllidoideae, tribe Hippeastreae). They generally have large fleshy bulbs and tall broad leaves, generally evergreen, and have large red or purple flowers. The name Hippeastrum, given to it by William Herbert, means “Knight’s-star-lily”, It is a lily for sure.
