You don’t see flowering quince planted in commercial or big residential landscapes very often. Professional designers tend to overlook it, opting instead for rock-steady performers that look great 52 weeks out of the year. Flowering quince does not. It’s like I was in calculus: A-plus one week, then struggling to pass two weeks later. But unless you have a townhouse garden or a zero-lot-line property, you probably have space to tuck one flowering quince into the back of your plantings.
