Growth—

Pyrola asarifolia is a plant of cool, moist climates and is known to be very cold tolerant, tolerating temperatures falling as low as -40°c. It grows in areas where the growing season can be as short as 2 - 3 months[1]. Prefers a moist sandy woodland soil[2, 3] in a cool position with partial shade[4, 5, 3], though it is tolerant of very heavy shade[1]. Requires a peaty or leafy acid soil that remains moist in the summer[3]. Soil pH is typically below 5.0[1]. Pyrola species can be very difficult plants to grow. They require a specific mycorrhizal relationship in the soil and therefore need to be grown initially with some soil collected from around an established plant of the same species[3]. They are also very difficult from seed. as well as being intolerant of root disturbance which makes division difficult[4].

Propagation

Seed - the only information we have on this species is that it is difficult from seed and germinates infrequently[3], and also that germination is better in the wild after there has been a non-intense forest fire[1]. We would suggest sowing the seed as soon as it is ripe if this is possible. Sow it into soil collected from around an established plant, only just covering the seed, and put the pot in a shady part of a cold frame. Consider baking the seed in the seed compost for a short while (up to 60 minutes) at 50°c[1]. Pot up any young seedlings as soon as they are large enough to handle, once again using soil from around an established plant. Plant out into their permanent positions when the plants are large enough. You should not need to use soil from around an established plant to do this since the soil in the pot will contain the necessary micorrhiza. Division with great care in the spring[4, 2]. Pot up the divisions using some soil from around an established plant, grow on in a lightly shaded part of a greenhouse or frame and do not plant out until the plants are growing away vigorously[3].
