I got a huge calla lily and plan to grow it in a houseplant (instead of outdoors--I've lots of other plants planned for outside). How do calla lilies do indoors? Do they stay evergreen? I love the flowers, but the spotted leaves are quite pretty too. Just wondering if they stay evergreen (if kept inside, of course) all year long. I don't really like plants losing their leaves and going dormant--*seems* like they're dying! lol, anyways, just wondering. Also, about how long does a single calla lily flower last? So I know whether my plant has fresh flowers or not... Thanks for any help!
