The inflorescences will keep blooming in full for months, in spite of the severe hot weather, drought or poor soil.
The plants are consistent and full.

These flower seeds do not need light to germinate, so cover trays or containers with a black plastic sheet or a newspaper. Remove the plastic cover on a regular basis to sprinkle by misting. When seedlings emerge, they require intense light, but indirect sunlight as a south-facing window. Keep the temperature of the room above 70 F.
Periwinkles can be moved outside as soon as the temperature levels are constantly above 65F degrees.
Direct sowing Periwinkle seeds, is not recommended.
However, if you are going to direct sow, adopt the exact same process as above.
Wait until the risk of frost has gone and temperature levels are constantly warm.
Just make sure the soil is well prepared, it is enough light and everything should be fine.
