Acer mandschuricum (Manchurian Maple) seeds - RP Seeds

Acer mandschuricum (Manchurian Maple) seeds


A surprisingly little known, graceful Maple, native to Siberia, Korea and Manchuria, which is rarely seen, even in botanical gardens. Has very attractive, dark green leaves composed of three, narrow, pointed leaflets and unusual scarlet-red leaf stalks. These lovely leaves turn a beautiful, rosy-red in the autumn. Its upright habit and spreading crown make it an excellent tree for training as a standard and Bonsai specimen. Very cold tolerant and fully hardy in this country.  

Hardy Tree
Height: 10m if not pruned
Position: Sun

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.
