My seeds of showy mountain ash (Sorbus decora), cold stratifying in the fridge, showed signs of germinating so I planted the little sproutlings in potting soil and put them in the coldest window, to delay their growth enough to allow the calendar to catch up to them. They are reaching for light a bit, but they are very cute.
Seeds of plants which grow in cool conditions may start to germinate in the fridge. Especially when I haven’t grown the species before, I may estimate that they need a much longer cold-moist stratification period than they do. It is useful to check on stratifying seeds — about once a month should do in the winter, more frequently as the season progresses.
I collected the showy mountain ash seeds in Nova Scotia this past September. I have very fond memories of this lovely shrub/small tree from a visit, some years ago, to Newfoundland in early October. Bright orange clusters of mountain ash fruit were everywhere, the most colourful thing in the landscape.
