LOBELIA hybrid Techno ‘Heat Upright Blue’

Lobelia –

0426 “Usually grown as an annual, edging lobelia is a prolifically blooming tender perennial. From spring until fall, ‘Tech Heupbule’ edging lobelia in the hybrid Techno Heat™ Series produces masses of white flowers with a subtle blue tint on well-branched, semi-upright stems with narrow dark-green foliage. This cultivar trails less than other members of the Techno Heat Series. Traditional lobelia tends to die back during hot weather and reblooms as the weather gets cooler. But Techno Heat™ Upright Blue has been bred to withstand the hottest summer temperatures while blooming nonstop.

Edging lobelia prefers deep, moist but well-drained, fertile soil, full sun to partial shade. Edging lobelia is an excellent choice for borders, beds, rock gardens, hanging baskets, and containers. Potential health hazards are associated with lobelia.”

Site Location
Annual lobelia will grow nearly anywhere. Lobelia seeds can be sown directly in the garden or indoors for later transplanting. These plants typically require an area with full sun but will tolerate partial shade. They also prefer moist, rich soil.

Planting Instructions
Start indoors about 10-12 weeks prior to the last frost in your region. Spread the tiny seeds just on top of the soil and water thoroughly. Place them in a warm, well-lit area.
The seedlings should pop up within a week or two, at which time you can begin thinning them out. After all danger of frost is gone and the plants are at least 2-3 inches tall, transplant them to the garden—spacing about 4-6 inches apart.

Care
Once established, the lobelia plant requires little maintenance. During hot, dry periods, care of lobelia requires that the plant should receive frequent watering, however, especially those in containers. A general-purpose liquid fertilizer can be given once a month or every 4-6 weeks, if desired.
Lobelia should delight your garden with beautiful blooms about mid-summer, continuing on up to the first frost. Although not necessary, you can deadhead lobelia plants to maintain a neat appearance.

Companion Plants
Primrose – Near ponds and streams, spring-blooming primroses of many sorts are charming with their white, pink, or yellow flowers, often in tiers one above the other. Later on lobelias bring interest to the same area.
Iris – The glorious open flowers of Japanese iris bloom with the earliest lobelias with a contrast in flower shape. Both thrive in damp soil.
Astilbe – Astilbes bloom with fluffy plumes of red, pink, or white flowers just ahead of lobelias, which then carry the colorful interest into fall. They enjoy similar conditions.
Turtlehead – The rounded mounds of handsome dark foliage and inflated pink or white flowers of turtlehead make fine companions for lobelias where soil is rich and damp.
