Striking trailing plants for hanging baskets and pots.
Intense blue flowers over light green foliage provide brilliant, eye-catching color for the patio all summer long.
Ideal for all types of container.
Best bloom i from June to October. Like pansies and linaria, these plants perform beautifully in cool spring weather, but begin to rebel at the onset of hot and humid summer weather. In the event foliage and flowering significantly declines in summer, consider cutting back plants to encourage a fall bloom or simply removing them from the garden.
Tender perennial (zones 10-11), but grown as an annual. It is best grown in organically rich, evenly moist, well-drained soils in full sun to part shade.
Appreciates regular fertilization (every 2 weeks) throughout the growing season.

1. Fill a clean nursery flat with soilless potting mix. Put the flat in a nursery tray that can hold water.
2. Sow trailing lobelia seeds on top of the potting mix. Do not cover them with soil since they need light to germinate. Press them gently in place with the bottom of another clean nursery flat.
3. Water the planted seeds by putting water into the nursery tray and letting it soak up into the flat filled with soil. Empty the extra water out of the tray after the soil has become thoroughly wet to prevent soil from staying too wet, which encourages damp-off.
4. Put the flat on its tray under grow lights where temperature is between +20-+22C. Use a heating mat if necessary.
5. Monitor the flat frequently for germination and for water needs. Water from the bottom as needed to keep the potting mix evenly moist but not soggy. Watch closely for damping off once seedlings emerge, because lobelia seedlings are prone to this fungus infection. Use a fungicide if necessary.
