It is a small deciduous tree growing to 10–15m tall with a trunk up to 40 cm diameter, though usually smaller and often with multiple trunks, and a spreading crown of long, arching branches. Young branches begin purplish in colour, older bark remains smooth but becomes olive-green in colour with regular narrow vertical white striations on young trees.
This is not a difficult tree to grow and will perform well planted on almost any well drained but moist soil. Prefers part shade, particularly in hot summer climates.
These seeds are collected from a large group of this species growing in an arboretum. Under the parent trees is a profuse carpet of naturally regenerated snake bark maple seedlings.
Snake bark Maple seeds have a relatively short and uncomplicated dormancy that is easy to break down. Full information on how to do this is included with every order.
Germination, Sowing and After Care Information for
Father David's Maple (acer davidii)
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.
Write the date on the bag so that you know when the pre-treatment 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 1 cm deep. For larger quantities it is easiest to sow the seeds in a well prepared seedbed outdoors once the warm and cold pre-treatments have finished and wait for the seedlings to appear.
It has also been found that fluctuating pre-treatment 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 pre-treatment 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 40 cm 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.
