Growing Larkspur from seed can be a slightly erratic affair but follow my line and you won’t go far wrong…at least I hope not.
Larkspur have long been a mainstay in country cottage gardens the length and breadth of our fair Isles. Wonderful dense spikes of flowers in a myriad of colours are a florists dream. Use them to add height and drama to your displays.
“Larkspur: These annual delphiniums, with their tall.papery flowered spikes in whites, blues, pinks and reds, are hot favourites with florists, and will crop reliably over a good two month period from a single sowing. They are much grown by specialists in making real-flower confetti, for fresh and dried use. If conditioned, the flowers don’t wilt quickly out of water, so are useful in hair garlands and buttonholes”
*It is best to pop the seeds in the fridge/freezer for a week or so before sowing.
*I sow two batches…one in March/April and one in early September. Some folk sow as early as February but I find if they sit around in wet soil they will simply sulk and end up ‘not living their best Larkspur….having said that, I would sow them in pots under glass in Feb and just water them lightly.
*They like a good dollop of sunshine, so avoid shade or semi shade. Soil must be free draining and light…add some organic material and grit if your soil is clay. (Shudder)
*I sow in straight rows in a thoroughly weeded bed, Don’t skimp in this weeding malarky…you will live to regret it.
*Cover the seeds very lightly with either soil or compost and keep the seed bed moist…don’t let it completely dry out, this is pretty easy in April.
*In a few weeks when your lovely Larkspur seedling bunnies are an inch or so high…thin them to about 10 inches apart.

*when they are a little taller, a layer of mulch will help keep the weeds down.
*It’s important to note that Larkspur seeds can be erratic to germinate and sometimes take up to six weeks to show themselves if they are feeling treacherous…don’t pile in with the hoe too early thinking that the crop has failed.
In 2024 we have Larkspur ‘Imperials’ and ‘Hyacinth’…both can be found in the shop. :)
