Do Columbines come back every year?
Also to know is, do Columbines bloom more than once?
Late spring and early summer are the season for columbines, and the flowers last for about four weeks before their droop sets in. As a perennial, columbine's life cycle for returning every season is short-lived. A new planting may be required after three seasons to round out the fullness of your garden.
Also Know, will Columbine rebloom if deadheaded?
Not all plants will rebloom if deadheaded, however. If plants like foxgloves, columbines, salvia and catmint aren't given the chance to form seeds, they can't throw them all over your garden.
Timing Pruning Extend columbine's bloom period by pinching spent flowers back to just above a bud. Columbines can be cut back to about one-half of their height after flowering to keep the plant attractive and green for the remainder of the summer and stop the center of the plant from opening up and looking bare.
