This the my last installment in the Reblooming shrub series. Cearly there are plenty of shrubs that bloom for a long period of time. I'm sure I left something out so please feel free to comment and share your favorite rebloomers.
Abelia x grandiflora is a superb rebloomer if you live in zone 6 or a warmer climate. Hummers and butterlies will visit the plant providing added enjoyment. This selection is called Bronze Anniversary. Its leaves emerage an attractive bronze-orange color then age to lime-green.
While most all Buddleia are reblooming if you dead head them Lo & Behold 'Blue Chip' starts blooming early and continues without having to deadhead. Additionally this selection non-invasive and is the only available cultivar that can be sold in Oregon.
Daphne transatlantica (D. caucasica) is a favorite of mine. It has small, fragrant, white flowers that start in April and can continue sporadically right up into fall.. It a small shrub about 3-4 feet tall and is one of the easiest daphnes to grow. I took this photo in the fall at the Arnold Arboretum in Boston.
One of you commented about Kerria japonica. You're right - it is a good reblooming shrub. It's a great shrub for the shade or semi-shade. This cultivar is called 'Alba' which is not white as the name would indicated but rather a butter yellow as opposed to the typical bright gold. It's hard to find but worth growing. I like it!
