What, if any, azalea will grow in Indiana, outside?

again, thanks

They typically just bloom once a year, but when treated like you treat it, it could surprise you and bloom again. Alway prune just after it finishes blooming, because the new growth will start forming new flower buds in a month or two. It is more apt to bloom again after it goes through a cool spell. Some florist azaleas can be easily tricked into blooming twice a year, so good luck.

hi, i also live in zone5 in in. yes there are many hardy azaleas that do well in z5. they are the native ones. they are decidous ,they bloom later that the exbury and norther lights they have a much better fragrance. the foilage color in fall is beautiful.
