GTry to plant in a location that enjoys full sun and remember to water moderately. Neon is generally regarded as a tender plant, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. Neon needs a loamy soil with a ph of 6.1 to 7.8 (weakly acidic soil to weakly alkaline soil).
Sow March to May. Sow seeds outdoors where they are to flower. Prepare the ground well and rake to a fine tilth before sowing. Sow 12mm (½in) deep, in rows 30cm (12in) apart.
For spring/summer flowering pot plants: Sow in a cool greenhouse or conservatory in late summer/early autumn. Grow on cool in full light and water sparingly.Sow 0.2 inches (0.5 cm) deep with a guideline distance of 7.8 inches (20.0 cm). For optimal germination, soil temperature should be a minimum of 10°C / 50°F.
By our calculations, you should look at sowing Neon about 35 days before your last frost date.
The petals can be used as a substitute for saffron in soups, rice or omlettes. They also look good in salads.
