FAQs
When do these delphiniums flower?
They are specifically bred to flower earlier than traditional varieties, beginning their display in June.
Can I grow these in pots?
Yes, they perform very well in large containers, provided the pots are deep and heavy enough to support their 1.2m height.
Are they harmful to pets?
Delphiniums are considered toxic if ingested. Keep them in areas where pets or children are less likely to graze on the foliage.
Do I need to protect them from winter?
Delphiniums are perennials and are generally hardy; however, ensuring the soil is well-drained in winter will help prevent the crowns from rotting.
How do I ensure I get a second round of flowers?
Cut back the flower spikes completely after the first bloom to encourage the plant to put energy into a second growth cycle.
How much sun do they need?
They thrive best in a sunny position. Full sun helps produce the strongest stems and the most vibrant flower colors.
Troubleshooting
Stems falling over or bending
The plants likely need support. Install garden stakes or circular plant supports early in the growth cycle.
No second flush of flowers
Ensure you have pruned the stems back to the base immediately after the initial flowering period ends.
Wilting during hot weather
Delphiniums require moisture-retentive soil. Increase your watering frequency during dry spells and consider applying a mulch to retain soil dampness.
Pros and Cons
Pros
- Striking visual contrast between blue-purple and white spikes

- Requires support in windy or exposed garden areas
- Needs consistent monitoring for moisture in dry periods
- Less effective if planted in poor, non-fertile soil
Setup, Compatibility & Care
For the best results, plant your 3-litre pots in a location that receives full sun and is protected from harsh, direct winds. Ensure the planting site has fertile, moisture-retentive soil that drains well to prevent waterlogging. If you live in an exposed area, install a bamboo cane or a ring support early in the season to prevent the tall stems from snapping under their own weight. During the peak of summer, monitor soil moisture; if the surface feels dry, deep watering is essential. Once the first flush of flowers has finished, cut the stems back close to the base; this often triggers a second, smaller flush of blooms later in the season. Feed periodically during the growing season with a balanced, organic fertilizer to maintain strong, upright growth.
