Liriodendron tulipifera (Tulip Tree) seeds
Height: to 25m
Position: Sun or semi-shade and preferably slightly acid soil
Packet of 15 seeds
Sowing Instructions: Sow at any time of the year. Mix equal parts of peaty seed compost, eg. Levington with vermiculite, perlite or horticultural grit and sow seeds very thinly on the surface, then just cover them with a layer of compost, vermiculite or perlite. Seal inside a polythene bag and place in the fridge for 3 months. [If sowing a large quantity, mix seeds with the compost/vermiculite and place in a resealable bag in the fridge, then sow into trays or directly outdoors in a nursery bed.] After this, move to a propagator or other warm place and maintain an optimum temperature of 18-21C. Germination should take place within 1-3 months. Note: Germination can be very erratic, so sow thinly and prick out the seedlings as they become large enough to handle disturbing the rest of the compost as little as possible. Occasionally, the seeds may need another cold spell in the fridge before they will germinate.
An alternative method is to sow in pots as above during late summer to early winter then place in a cold frame and let nature take its course as the seasons change with the seedlings emerging the next spring.
Growing Instructions: Transplant seedlings when large enough to handle into 7.5cm pots and grow on in a cold frame or nursery bed for a year or two then plant in their final position in sun or semi-shade, and preferably slightly acidic soil.
