Opinion
"
The hardiest of all pear trees; this deciduous tree can thrive in cold climates. It produces stunning flowers during bloom and retains a lovely autumn colour. Simple to ovate glossy leaves. Fruit is also used to make edible food. Overall, a good choice for planting as an accent or ornamental.

| Starting the seed is best during the autumn, as it is ripe enough to be sowed into a cold frame. You can also do cold stratification; this requires 8-10 weeks (about 2 and a half months) with a temperature around 1°C. Be sure to sow the seeds as early as you can for maximum potential. Seeds will mostly germinate mid to late during the winter months. Watch temperatures over 15-20°C as they can interrupt the growth of the seed, causing a secondary state of dormancy. Transplant the seeds into pots once big enough and keep them in a greenhouse or a cold frame for the first year of growth. |
