Cornus controversa (Wedding Cake Tree) seeds
Fine architectural, small tree or shrub originating from China and Japan which has been grown in the UK since the 19th century. The branches of this showy tree are arranged in tiers and look spectacular in early summer when smothered in clusters of tiny, star-shaped, white scented flowers. These are followed by green berries ripening to blue-black in autumn which are much loved by birds. As an added bonus, the leaves turn rich shades of red and purple for a lovely autumn display.
A stunning tree for all seasons!
Height: to 15m
Position: Full sun or semi-shade - avoid very cold winds

Packet of 20 seeds
These seeds have a double dormancy which needs to be broken before they will germinate, ie. they need to go through a process which simulates the changing seasons.
Sowing Instructions: Sow at any time of the year. Soak seeds for 24 hours in water which starts off hand hot. Sow very thinly in trays or pots of moist, peat based seed compost (eg. Levington), lightly cover with compost and seal inside a polythene bag. Maintain an optimum temperature of 20C for 16 weeks, then place the container(s) in the fridge for a further 8 weeks. Then, return to 20C and germination should take place. Throughout this process check regularly and ensure the compost does not dry out. 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.
Alternatively, sow as above, seal in a polythene bag and place in a cold frame or sheltered part of the garden and let nature take its course as the seasons change. (I personally find this gives the best results)
Growing Instructions: Transplant seedlings when large enough to handle into 7.5cm pots. The little trees are best grown on for a year or two in pots and protected from frost for the first winter. Plant out once established in a sunny or semi-shaded position sheltered from cold, drying winds.
