Lobelia is a trailing warm weather annual and tender perennial, native to South Africa. From spring until fall, the Techno Series produces masses of delicate flowers on trailing, well-branched stems with narrow dark-green foliage. Traditional Lobelia tends to die back during hot weather and re-blooms as the weather gets cooler, but the Techno Series has been bred to withstand the hottest summer temperatures and continue in nonstop blooming. Lobelia is most desired for its delicate, ever blooming colors, heat tolerance, low maintenance requirements, and mounding habit.
Techno Heat Dark Blue has dark blue-purple flowers that sit on mid-green foliage. This beautiful plant has a medium-compact nature and has a trailing growth habit. Syngenta has mastered the Lobelia genetics and created the Lobelia Techno, Techno Heat, and Techno Heat Upright series. It is commonly used for mass planting in the landscape, or featured in hanging baskets and other containers combinations. Taller and fuller varieties with an upright habit go nicely as mixed fillers in the garden, while varieties with a trailing and mounding habit go well in potted combinations, window boxes, and hanging baskets. Lobelia grows best in moist, fertile, well-drained soil, and is a full to partial sun exposure flower. Lobelia thrives in the heat and is easy to grow. Techno Heat Dark Blue will bloom all season long. A key feature of Lobelia Techno Heat Dark Blue is that it is heat tolerant and does not require deadheading.
Growing Tips for Homeowners:
As with every plant purchase, it is important to look for quality at the start! During the purchasing process, be sure to avoid plants that look exhausted. Finding a fresh young plant, without yellowing foliage is very important. Look for rich green foliage as indication of the plant's care thus far. This will ensure an easy start for you, and a long life for your plant.
After locating and purchasing a quality plant at the store, it is important to find the perfect place for it at your home. Lobelia is a full sun annual that thrives in the heat. The best time for planting your flower is mid-spring or early summer, after the threat of frost has passed. Be careful not to take your plant outside too early in the spring. If there is still a chance of frost in your area, keep your plant indoors, maintaining care in the container. Lobelia will last from late spring, through the summer, until the finish of fall. They are good pioneer plants in the garden, until other plants become more established.
Lobelia Techno Heat Dark Blue is a low maintenance plant that is heat tolerant. Regular water application, along with fertilizer or compost application will ensure optimal plant performance. Be sure to apply low to the ground, near the plant’s main stem, avoiding wetting the plant’s foliage, for quick absorption and utilization. Lobelia requires a good moisture level but must be well drained. It is important to ensure good drainage in both containers and landscaping, to prevent diseases like root rot. Drainage holes, elevated flower gardens, and proper soil composition are three great ways to prevent root rot and help your plants maintain a healthy moisture level.
These beauties will continuously bloom all season, and while the plant does not require deadheading, if your plants start to look messy, feel free to trim them back to keep them tight and well shaped. After pinching back, your plant should begin to bloom again within 1–2 weeks. It is good to remove the spent flowers to encourage continued flower bud production.
Preparing the ground for your plants is always an important key to maintaining healthy plants. Pests like slugs and snails are attracted to the environment created in flower gardens and landscaping. Prevention of these types of pests includes clearing the area of holes where such pests can live. Aphids and thrips may also pose a threat to your Lobelia, but are usually taken care of by predator insects. These tiny pests usually hide on the underside of leaves and are difficult to see because of their small size.
The earliest prevention against disease and pest threat is careful examination during the purchasing process. It is important to know the difference between harmful pests and beneficial insects. Some insects may lay their eggs on your plant’s leaves in order to feed on the pests, which is actually beneficial to your flower. Removal of the wrong eggs could potentially promote pest survival and growth. Lobelia flowers attract butterflies, adding a touch of beauty to your garden while promoting pollination and plant growth.
