Description:
Lobelia x speciosa 'Vedrariensis' is a herbaceous perennial that typically grows to a height of 2 to 3 feet (60 to 90 cm). It features lance-shaped, dark green foliage arranged in an alternate pattern along the stems. The real showstopper of this cultivar is its vibrant, cardinal red flowers.

Care Guide:

Lighting: Lobelia x speciosa 'Vedrariensis' thrives in partial shade to full sun. It prefers a location with at least 4 to 6 hours of direct sunlight per day. However, in hotter regions, providing afternoon shade can help protect the plant from scorching. If grown in full shade, the plant may produce fewer flowers and have a less compact growth habit.

Water: Lobelia x speciosa 'Vedrariensis' prefers consistently moist soil conditions. It thrives in well-drained but moisture-retentive soil. Regular watering is important to keep the soil evenly moist, especially during hot, dry periods. However, be cautious not to overwater, as excessive moisture can lead to root rot. Mulching around the base of the plant can help retain moisture and regulate soil temperature.

Soil: Lobelia x speciosa 'Vedrariensis' prefers rich, humusy soil that is well-draining. It can tolerate a range of soil types, including loam, clay, or sandy soil, as long as it retains moisture. Amending the soil with organic matter, such as compost or well-rotted manure, before planting can improve its fertility and moisture retention capabilities.

Temperature: Lobelia x speciosa 'Vedrariensis' is hardy in USDA hardiness zones 3-9. It is adaptable to a wide range of temperatures but performs best in moderate climates. It can tolerate cool temperatures and is well-suited for temperate or woodland gardens.

Fertilizer: Lobelia x speciosa 'Vedrariensis' generally does not require heavy fertilization. However, a light application of balanced, slow-release fertilizer in early spring can promote healthy growth and flowering. Avoid excessive use of nitrogen-rich fertilizers, as they can promote excessive foliage growth at the expense of flowers.

Maintenance: Lobelia x speciosa 'Vedrariensis' requires regular maintenance to ensure optimal growth and flowering. Remove any spent flower spikes to encourage continuous blooming. Additionally, deadheading can prevent self-seeding and redirect energy to the development of new blooms. Cut back the stems to ground level in late fall or early spring to promote fresh growth in the following season.

Pests and Diseases: Lobelia x speciosa 'Vedrariensis' is generally resistant to pests and diseases. However, it may occasionally attract slugs, snails, or aphids. Monitor the plant for any signs of pest damage and take appropriate measures if necessary. Additionally, provide adequate air circulation and avoid overcrowding to prevent the development of fungal diseases.

By following these care guidelines, you can enjoy the vibrant red flowers of Lobelia x speciosa 'Vedrariensis' in your garden. Adjust the care routine based on your specific growing conditions and monitor the plant for any signs of stress or pest infestation. With proper care, Lobelia x speciosa 'Vedrariensis' will provide a beautiful display of color and attract beneficial pollinators to your outdoor spaces.
