The various delphinium hybrids embellish every garden with their tall, usually blue or white flowering flower candles. The lush splendor can even be lured out a second time by a targeted pruning after the flowers have faded.

Most delphinium species flower in June/July

Larkspur is a summer bloomer

Delphiniums are extremely versatile plants, as evidenced by the approximately 5000 different registered varieties. The large number proves that blue does not have to be boring, but has very different tones and variations. There are also Delphinium breeds that not only flower blue, violet or white, but also red, yellow or pink variations. What they all have in common, however, is that they unfold their enchanting blooms in early summer - usually between June and July.

Extend flowering time by pruning

It's just a pity that every flower is fleeting. This also applies to delphiniums, which develop their follicles with numerous seeds from mid to late July at the latest. If you do not want to get seeds, cut off all faded shoots to about 20 centimeters above the ground. Then the perennial invests its energies in new flowers instead of in the formation of seeds, which usually appear from the end of August / beginning of September. The second bloom of the delphinium can be admired between September and October, but it is not as lush as the first summer bloom.

win seeds

Delphiniums can be propagated very easily using self-collected seeds, which can simply be collected from the ripe follicles in autumn. But be careful, because all parts of the plant - and especially the seeds! - are highly toxic and should therefore be kept out of the reach of children and animals. Incidentally, you do not necessarily have to collect the seeds, as the delphinium sows itself very reliably.

tips and tricks

If you want to grow delphiniums from seeds yourself, make sure you know which variety the mother plant belongs to. F1 hybrids in particular are poorly suited for seed production, since their offspring always have completely different properties than the mother plant.
