How to Grow Quaker Bonnets, Bluets and other Hedyotis Plants in the Garden
Fresh seeds from Hedyotis plants should be planted in a sunny area of the garden at the end of Summer.
The seeds should be sown into vermiculite containers, and sunk into a shady area of the garden.
Germination usually takes from three to four weeks. Once Quakers Bonnets / Bluets seedlings have sprouted they should be allowed to grow for a further year, and then transferred to their final location the following autumn.
Ideally Hedyotis Plants should be spaced about 30 to 40 cm (12 to 16 inches) apart in the garden. Locate plants in a moist acidic soil of about pH 5 to 6.
Caring for Hedyotis plants
Once established it is important to keep Hedyotis plants such as Bluets well watered when they are growing.
More plants can be created by dividing the plants. This should be done regularly as Hedyotis plants have a short life span.
Following flowering allow the leaves to die fully before attempting to remove them.
