Usually growing no bigger than a large shrub this is recommended as a valuable garden plant that deserves to be planted more widely. It typically grows as a multi-stemmed specimen with elegant tiered branching like that of the Japanese Maples
Grows well in light shade as an under-story shrub beneath tall forest trees and prefers not to be in full hot afternoon sun as the leaves may burn if water is restricted. Prefers an acidic soil, rich in organic matter with regular water. Hardy to about -20°c
Maple seeds have a relatively short and uncomplicated dormancy that is easy to break down. This species is regarded as an easy maple to propagate and produces very uniform seedlings. Full information on how to do this is included with every order.
Germination, Sowing and After Care Information for
Vine Maple (acer circinatum)
Maple seeds of this species have a deep dormancy within them, this requires a degree of patience to overcome and it is usually quite easy to get high levels of germination if the correct procedures are followed.
First prepare a free draining substrate into which the seeds are to be mixed, this can be a 50/50 mixture of compost and sharp sand, or perlite, vermiculite. The chosen substrate needs to be moist (but not wet), if you can squeeze water out of it with your hand it is too wet and your seeds may drown and die. Mix the seeds into the substrate, making sure that their is enough volume of material to keep the seeds separated. Place the seed mixture into a clear plastic bag (freezer bags, especially zip-lock bags are very useful for this -provided a little gap is left in the seal for air exchange) If it is not a zip-lock type bag it needs to be loosely tied. Then write the date on the bag so that you know when the pretreatment was started.
Next the seeds are required to undergo a cold period to break the dormancy, this is easily achieved by placing the bag of seeds and compost in the fridge at (4 Celsius or 39F) for around 12 weeks. It is quite possible for the seeds to germinate in the bag at these temperatures when they are ready to do so, if they do, just remove them from the bag and carefully plant them up. When the period of pre treatment has finished the seed should be ready to be planted. Small quantities can be sown in pots or seed trays filled with a good quality compost and cover them with a thin layer of compost no more than 1cm deep. For larger quantities it is easiest to sow the seeds in a well prepared seedbed outdoors once the warm and cold pretreatments have finished and wait for the seedlings to appear.
It has also been found that fluctuating pretreatment temperatures can give the best germination results and I have myself had excellent results by keeping the mixed seeds in a cold shed through the winter for the cold stage of their pretreatment and allowing the temperature to fluctuate naturally. Ungerminated seeds can have the whole warm and cold process repeated again to enable more seeds to germinate.
Do not expose newly sown seeds to high temperatures (above 25 Celsius). Keep the seedlings well watered and weed free. Growth in the first year is usually between 10 and 40cm depending on the time of germination and cultural techniques and developing seedlings are usually trouble free. Allow them to grow for 1 or 2 years before planting them in a permanent position.
