Planting & Care
Larkspurs require cool temperatures to successfully germinate and bloom, so they grow best when sown directly in the garden in early spring before the soil warms. The seeds germinate reliably under the correct conditions and will mature to a height of 1 to 4 feet in just a few months. However, the seedlings are susceptible to rot and must be planted in quickly draining, mildly alkaline soil to survive into maturity.
Sunlight: Pick a spot with full sunlight or partial shade.
Soil: The soil should be average to rich and also well-draining.
Water: Keep soil moist throughout the growing season.
Temprature: 80 degrees and more.
Fertilizer: Apply any organic fertilizer.
- Since seedlings don’t transplant well it is best to sow the seeds directly in the ground.
- Cover the seeds lightly.
- The seeds must be close to the surface, because to germinate they need a lot of sunlight.
- Four inches apart is generally enough space, and do not put a lot of mulch on them.
- For optimum growth, it is best to group them into sections of 10 or 20 plants.
- It will take about a week for the seeds to germinate, so be sure to keep them moist during this time.
- Remember to keep the soil watered well to feed their fast growth.
- Wait until about two leaves appear on each plant and then thin them out to six inches apart.
Harvesting: Seed from Larkspur can be collected and saved for planting next year. Allow the flowers to go to seed, collect the tiny black seeds on a dry day, and store them in a cool, dry location. Saved seed retains it s viability for up to 6 months, after which time it starts to decline. Year old seed can have germination rates as low as 50 percent.
- Larkspur generally grows best in cooler weather.
- When the temperature rises to 80 degrees and higher, they will most likely die.
- But in general, it will grow fast with little maintenance until the first frost hits.
- As with most annual plants, frost will wipe them out.
- Also strong winds will damage them, so make sure they are well-shielded.
- If your larkspur grows too tall, it may have to be staked up as the blossoms get too heavy.
- But if they are planted about six 6 apart, they will support one another and won’t require staking.
- Larkspur usually blooms very early in the spring, before any other plants.
- If you need to add fertilizer to your soil, do so about once a month, but not after the larkspur have bloomed.
It is great used in arrangements with other flowers, or simply by themselves.
- The part mostly used for medicinal is the seeds, and their virtues seem to reside in alkaloidal principles (Delphinine, Staphisagrine and perhaps others) that are found in the shell of the seeds.
- Poisoning is possible if large quantities are consumed.
- (No culinary uses)
- The plant is used for ornamental purpose.
Larkspur seeds are toxic.

Buy ready to use nutrient rich soil:
In general use a soil-based compost placed over a generous layer of drainage material such as earthenware crocks, pebbles or gravel. Water and feed regularly, especially while plants are bearing flowers and fruit, when a high-potash fertilizer is recommended.
