Some knowledge about growing from seed is necessary to germinate even the easiest seeds.
Most seeds require humidity to germinate, even desert plants like
require that their growing medium remains moist until germination.|
Most seeds require oxygen to germinate, if buried too deep in their growing medium, or if the medium is too wet,
the seeds may not get the oxygen they require.
Lychnis arkwrightii x seeds will usually germinate in 21-30 days.
Lychnis arkwrightii x seeds have a hard seed coat that is impermeable to water, and which prevents the seed from imbibing.
Scarification: Large seeds can be chipped with a chizel, knife or rasp. Smaller seeds may be scraped on sandpaper, clipped with nail clippers or pricked with a needle. Try to do this on the side away from the hilum. After scarification seeds are usually soaked in warm water, which should be changed daily. Most seeds swell up when they are soaked, those that do should be sown immediately.
(pre-chill for 2 weeks).
