FAQs
When is the best time to sow Delphinium 'Hunky Dory Blue' F1 seeds?
Sow indoors from late winter to early spring. Earlier sowings will flower in the same year, while later sowings may flower the following year.
How tall do these delphiniums typically grow?
While they are described as compact, delphiniums generally require staking. Specific height varies, but expect them to need support as they develop flower spikes.
Are these seeds suitable for direct sowing outdoors?
It is recommended to start these seeds indoors to give them a head start. They should only be planted out after the danger of frost has passed and after a period of acclimatization.
What kind of soil do delphiniums prefer?
Delphiniums thrive in well-drained, fertile soil. Improving heavy soil with organic matter or grit can enhance drainage.
Can I grow these in pots?
Yes, this variety is ideal for patio pots and containers. Use a good quality compost and ensure the pot has adequate drainage.
What does 'F1' mean for these seeds?
F1 indicates that these are F1 hybrid seeds, meaning they are produced by crossing two specific parent varieties. F1 hybrids often exhibit improved uniformity, vigor, and disease resistance.
How should I deadhead the spent flower spikes?
Once the main flower spike has finished blooming, cut it back to the base or to a healthy side shoot. This encourages the plant to produce new energy for potential re-blooming.
Are these delphiniums safe for pets?
Caution: Delphiniums are listed as harmful if eaten by humans and pets. It is important to plant them in areas where pets and children cannot access or ingest them.
Troubleshooting
Seeds not germinating
Ensure consistent moisture and warmth (15-20°C). Check that seeds are not buried too deeply and are receiving adequate light. Try using a propagator for optimal conditions.
Seedlings are leggy or weak
Provide more light immediately. Ensure the temperature is not too high. Gradually acclimatize to cooler conditions once they are stronger.
Plants wilting despite watering
Check soil drainage. Delphiniums dislike waterlogged roots. Ensure the pot or soil has adequate drainage holes. Amend heavy soil with grit.
Flower spikes are bending or breaking
This indicates a need for staking. Install stakes early, before the plant grows too tall, to provide support as the flower stems develop.
Leaves have yellow or brown spots
This could be a sign of fungal disease, often due to poor air circulation or overwatering. Ensure adequate spacing between plants and water at the base to keep foliage dry.

Setup, Compatibility & Care Instructions
Sowing Indoors:
- Fill a seed tray almost to the top with moist seed compost.
- Sow seeds thinly on the surface and lightly cover with vermiculite or a thin layer of compost.
- Place in a warm location (15-20°C) and keep consistently moist.
- Ensure the tray is in a light spot, but out of direct sunlight.
Growing On:
- Once seedlings are large enough to handle, transplant them individually into 8cm pots.
- Gradually acclimatize the young plants to outdoor conditions over 2-3 weeks.
- Plant them outdoors only after all danger of frost has passed.
Planting Out:
- Choose a sunny, sheltered spot with well-drained, fertile soil.
- Space plants approximately 30cm apart.
- Alternatively, plant in patio pots using a good quality compost.
- Keep plants well-watered, especially during warm, dry weather.
Care:
- Delphiniums prefer fertile, well-drained soil and a sunny, sheltered position.
- Water and feed plants well during spring and early summer.
- Staking is essential to support the flower spikes as they grow.
- Remove spent flower spikes promptly to encourage a potential second flowering later in the season.
Compatibility:
This variety is suitable for mixed borders, rock gardens (if space permits), and container planting on patios and balconies. It pairs well with other sun-loving perennials.
