The delphinium (Latin delphinium) has been blooming in German cottage gardens for many centuries and always impresses with its bright, mostly blue, abundance of flowers. The classic perennial comes in many different varieties, most of which are perennial, but some are only one to two years old. Almost every Delphinium variety can be stimulated to bloom again by a strong pruning after the first summer bloom.
When does delphinium bloom and how do you encourage rebloom?
The delphinium (Delphinium) blooms with bright blue flowers in the summer months of June and July. A vigorous pruning after the first flowering can encourage re-blooming in September.
Cut larkspur after summer flowering
The grape-like inflorescences of the delphinium, which are sometimes very tall, especially in the varieties of Delphinium elatum (this is also called “high delphinium”), can be seen for the first time in the summer months of June and July. Immediately after flowering, cut it down to about 15 to 20 centimeters above the ground, because in many cases the plant will sprout again and bloom a second time in September.
Tips & Tricks
Since delphinium is poisonous, you should wear gloves when cutting to be on the safe side - although the individual parts of the plant are dangerous, especially if consumed, some people also react with a rash from mere skin contact with the plant sap.
