Andromeda polifolia, common name bog-rosemary, [2] is a species of flowering plant in the heath family Ericaceae, native to northern parts of the Northern Hemisphere. It is the only member of the genus Andromeda , and is only found in bogs in cold peat -accumulating areas.
It is considered a potentially invasive species and its seeds are often difficult to start, with a low germination rate and relatively slow growth, but the plant can live as long as 35 years. [10] [11] Forms range from upright to trailing; [7] the upright forms can reach between 1.2–1.8 metres (4–6 ft) tall. [12]
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.
Seeds in soil lose viability in less than 10 years. [16] Florida scrub communities typically experience fires at 15 to 100 year intervals, [17] which kill all plants, including rosemary. [18] If a scrub patch burns less than ten years after a previous fire, there will not be seeds available in the soil to sprout into new rosemary plants.
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.
