Full details
The Lobelia Speciosa Starship Blue is a hardy perennial designed for gardeners looking to add vertical structure and vibrant color to borders, cottage gardens, or patio containers. This plant offers long-lasting, deep blue flower spikes that bloom from mid-summer into early autumn, serving as a reliable attractant for bees and butterflies. While it is celebrated for its neat, clump-forming habit and ease of care, potential growers should note that it requires consistently fertile, well-drained soil to reach its full flowering potential.

FAQs
Is this plant deer-resistant?
While Lobelia is not typically a first choice for deer, no plant is entirely deer-proof if other food sources are scarce.
Does it need to be brought indoors for winter?
No, it is a hardy perennial and can remain in the ground or in its container outdoors, provided the container has adequate drainage.
How far apart should I plant them?
Space them roughly 30-40cm apart to allow for proper airflow and root development within the clump.
Can it grow in full shade?
While it can tolerate partial shade, the plant will produce the most vibrant blooms and strongest stems when given access to at least partial sun.
Does it attract pests?
Generally, it is quite hardy, but it is always good practice to monitor for common garden pests like aphids in the spring.
Troubleshooting
Flowers are wilting during the day
The plant is likely heat-stressed or water-deprived; ensure a consistent watering schedule during the afternoon.
Poor flowering output
The plant may need a boost in soil fertility; apply a balanced liquid fertilizer during the early summer months.
Leaves turning yellow
This is often a sign of waterlogged soil; check for drainage issues and adjust your watering frequency.

Setup, Compatibility & Care
When you receive your 9cm pot, acclimatize the plant to your local garden conditions gradually. For optimal growth, prepare your planting hole with organic matter or compost to boost soil fertility. Ensure the site is well-drained, as soggy roots are the primary cause of decline. During the growing season, remove faded flower spikes to encourage a secondary flush of blooms. In the winter months, although this variety is hardy, adding a layer of organic mulch around the base of the clump provides extra protection for the root system. Ensure the plant receives consistent moisture throughout the growing season, especially during hot spells in July and August.
