It looks like it is possibly a Cherry Nymph. I don't have that in my collection, so I don't know if the flowers fade with such significant striping/streaks of white on that cultivar. Regardless of name, it's obviously a happy plant!

Jane, It's very pretty!! Cherry Nymph is a large flower with very thick texture sort of like corduroy. Since mine never bloomed outside I couldn't tell you if it forms white streaks as it matures in the sun. What ever it is, it's very bright and cheerful a nice addition to any garden!!

Thanks!

what I love about it is, the flowers are thick and waxy. They shine in the sun. Very unlike my common amaryllis which have thin flowers.

Here is a cherry nymph - mine does have some white streaking although not the same pattern as yours, and I seem to remember that this increases with age, so this could be it

Jane, very very pretty. So nice that it grows so well in the ground! Tempting me more and more to plant in the ground :) - J
