The classic Clematis beloved by gardeners for more than 100 years, C. x jackmanii blooms so heavily from June through September that you should abandon all hope of viewing the foliage! One of the loveliest climbers of all time, it will remain a beloved favorite as long as gardeners treasure profuse, rich color!

The 4-petaled blooms are held wide open and measure 4 to 6 inches across. They arise by the hundred (thousand?) on climbing plants that eventually reach 12 to 30 feet high and 4 to 5 feet wide. Not a plant for the mailbox, this is a Clematis you want to blanket your fences and outbuildings, spreading its royal glory for 4 months at a stretch every summer!

'Jackmanii' can also be grown through strong, tall shrubs and trees. The blooms are excellent for cutting; just float them in a bowl of water for a lovely table centerpiece. They never fail to make an attention-getting display!

Best in light (not deep) shade, such as that provided by the high canopies of tree branches. Zones 4-9. Pruning Group III.
