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.
Asclepias speciosa seeds will usually germinate in 30-90 days, even under good conditions germination may be erratic.
Asclepias speciosa seeds need to be "overwintered" before they will germinate.
Stratification; cold treatment or vernalization. Seeds of some species need just a couple of weeks, others 3 months. Seeds can be stratified in dampened peat or sand, in a plastic box or bag at 4°C or 5°C in a refrigerator. The seeds should not be frozen or in a wet medium. Very small seeds can be sown on the surface of their growing medium, in pots sealed in plastic bags, and kept in the 'fridge. Many vernalized seeds need light to germinate when they are sown in the "Spring".
(Pre-chil for 3-4 weeks).
