...or the Rodney Dangerfields. Deciduous flowering shrubs get little enough respect as a group, and I'm thinking that, excepting forsythia, weigelias are the low rung on that totem pole. It is true that they take up a lot of room and only look good for a few weeks a year, but. Their shape, gawky with multiple arching branches, works wonderfully for those few weeks that they're covered with flowers. And a few, actually a good number, of them rebloom lightly.
The older I get (and the more perverse?), the more I appreciate these plants. The red one is 'Red Prince', one of the "usual suspects" at the garden center; they were only planted last year so they're really just babies. The middle plant with multicolored flowers, they darken as they age, is a favorite. The plants, there are more than one, in the bottom photo were renewal pruned last year and they did a darned good job of renewing themselves. Still, if you want to grow these older larger selections, you're going to need a good bit of property.
