Trailing plants for hanging baskets and pots.
A favorite variety with bright, vivid blue flowers and tiny white eyes that catch the light.
Long flowering and is an ideal container companion.
Blooms 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.

Sow from January to April inside.
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.
