Larkspur (Latin: Delphinium) has been flowering in German cottage gardens for many centuries and never fails to impress 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 annual or biennial. Almost every Delphinium variety can be stimulated to bloom again by vigorous pruning after the first summer bloom.
If you cut back delphiniums after the first bloom, they are likely to bloom a second time
Prune delphiniums after summer flowering
The floriferous inflorescences of Delphinium elatum (also known as "tall larkspur"), some of which are very tall, can be seen for the first time in the summer months of June and July. Immediately after they have faded, cut them back 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 and tricks
Since the 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 when eaten, some people also react with a rash through mere skin contact with the plant sap.
