It is not exactly known how long dry plant specimens last in storage, but with proper conservation, they have been able to last many centuries. Specimens collected by Linnaeus in the eighteenth century and by Banks and Solander on the Endeavour voyage in 1788 are still excellently preserved. [4] The specimens may be whole plants or plant parts.
Cold stratification simulates the natural process by subjecting seed to a cool (ideally +1 to +3 °C [34 to 37 degrees Fahrenheit]) moist environment for a period one to three months. Seeds are placed in a medium such as vermiculite, peat, or sand and refrigerated in a plastic bag or sealed container. [1]
Marjoram (/ ˈ m ɑːr dʒ ər ə m /, [2] Origanum majorana) is a cold-sensitive perennial herb or undershrub with sweet pine and citrus flavours. In some Middle Eastern countries, marjoram is synonymous with oregano, and there the names sweet marjoram and knotted marjoram are used to distinguish it from other plants of the genus Origanum.
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.

The soaking increases the water content in the seeds and brings them out of quiescence. After draining and then rinsing seeds at regular intervals, the seeds then germinate, or sprout. For home sprouting, the seeds are soaked (big seeds) or moistened (small), then left at room temperature (13 to 21 °C or 55 to 70 °F) in a sprouting vessel.
Origanum syriacum subsp. syriacum; syn. Majorana syriaca (also Origanum maru, although this primarily refers to a hybrid of O. syriacum), [4] bible hyssop, [5] Biblical-hyssop, [1] Lebanese oregano [1] or Syrian oregano, [1] is an aromatic perennial herb in the mint family, Lamiaceae.
A species forming no soil seed bank at all (except the dry season between ripening and the first autumnal rains) is Agrostemma githago (Corncockle), which was formerly a widespread cereal weed. [citation needed] Longevity of seeds is very variable and depends on many factors. Seeds buried more deeply tend to be capable of lasting longer. [18]
