Orthodox, that is to say seeds with the capability to withstand desiccation and freezing temperatures (-20°C) and may therefore be conserved for years, if not decades.
For germination, you must...
1. allow TWO MONTHS for seed treatment;
2. subject them to a scarification AND a cold stratification before sowing (follow the steps below in order).
Scarification : Soak the seeds in water at room temperature for 24 hours.
Stratification (cold) : Place the seeds in a bag (Ziploc Slider type) containing slightly premoistened peat moss. Seeds should be surrounded by the latter. Close the bag and place it in cool storage (between 1°C and 5°C) for approximately two months.
Seedlings : Remove the content from the bag and sow the seeds by broadcasting the mix on the growth medium. Bury very lightly, less than one millimeter from the soil surface.
Comments : Mountain Laurel seeds would require light to germinate. That is why it is important to sow the seeds at the surfce of the growth medium or very shallowly (about 1 mm under the surface).
