Acer palmatum dissectum atropurpureum (Cut Leaf Japanese Maple) seeds
A lovely form of Japanese Maple is this mound-forming deciduous shrub with deeply divided, lacy, bronze-red or purple cascading foliage which turns brilliant red, orange or yellow in autumn. Mature shrubs have small, reddish-purple flowers in mid-spring. Gorgeous grown as a specimen shrub on its own or as a backdrop to a border or large bed.
Easy to grow from seed and fully hardy when mature. Will need frost protection for the first couple of winters.
Height: 1m, Spread 1.5m if not pruned
Position: Sun or semi shade and well-drained soil
Flowers: Mid-spring on mature plants
Packet of 10 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. Sow very thinly in trays or pots of moist seed compost (eg. John Innes), lightly cover with compost and seal inside a polythene bag. Maintain an optimum temperature of 18-21C for 8 weeks, then place the container(s) in the fridge for a further 8 weeks. Then, return to 18-21C 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 at least the first winter. Care should also be taken to protect them from late spring frosts which can be very damaging. Plant out once established in a sunny or semi-shaded position out of the strong midday sun and sheltered from cold, drying winds. Acers generally will give their best autumn colour in neutral to acid soil or ericaceous compost.
