Sow Delphinium - possible between March and September
Apart from the non-semen F1 hybrids - whose offspring always have completely different characteristics than the mother plants - almost all Delphinium varieties can be propagated very well via seeds. But also a vegetative propagation over division works very well with the larkspur.
Collect seeds and keep them properly
If you do not cut back the withered panicle of the delphinium after the summer bloom, but instead leave it on the plant, this puts her energy into the training of seeds. The Larkspur develops narrow follicles that contain several triangular black seeds.
Absorb follicles before bursting
In the fall you can pick up the fruits as soon as they turn brown. However, you should not wait too long, otherwise the fruit will burst and the plant will self-sow. The seeds are cleaned and then immediately filled into a dry, airtight container. Keep them cool (optimally 0 to 5 ° C) and dark until spring.
Larkspur preference from March
From March, the delphinium in the cold frame under glass can be preferred. The local windowsill is rather unsuitable for this project, because it is usually too warm for the plant there. The delphinium is a cold germ, d. H. The seeds need a cold period before they start to germinate. Even collected seeds germinate usually at about 5 to 12 ° C, only purchased varieties also have on the windowsill a high germination rate.
Sow Delphinium
Delphinium takes about four weeks to germination.
Direct sowing between May and September
The direct sowing of the delphinium is much easier: Put the - in self-collected previously stratified seeds - just in well-loosened, fine crumbly soil and protect the sowing with a net or the like from hungry birds. Self-collected seeds need a cold spell if possible before they germinate better. This can be done from March outside or in the vegetable compartment of the refrigerator. Under no circumstances should the seeds be exposed to frost, d. H. please do not put it in the freezer!
Tips & Tricks
If you want to do as little work as possible, just let nature take its course. Most delphiniums sow themselves very reliably, if they are left.
