Last summer I purchased some Trident maple and Amur Maple seeds from Angelgrove Seed Co. I followed the instructions that came with them for stratification and planting.

Also, all my black pines and lacebark pines came up too, so I know I did something right. Neal This is not unusual. Trident maple, Acer buergerianum is just like Acer palmatum with regard to seed germination. Once the seed is thoroughly dried and stored, it is extremely difficult, if not impossible to get it to germinate. Acer buergerianum is best collected fresh in the fall and immediately soaked and stored in the refrigerator for the winter. I understand that this may be next to impossible when buying seed from a company. I think you are in N. CA. There are a number of larger Tridents planted in the landscape in this area since the weather is mild enough for them. I get my seed from a huge tree on the Santa Rosa Jr. College campus in Santa Rosa. There is one thing you can try. Many Acer species need multiple pretreatments to break down a series of germination inhibitors. Since you have given it a cold moist pretreatment, proceed to a warm moist one. Keep it at 70F for three months, or through the summer, then put it back in the refrigerator this fall for another cold pretreatment. You should never allow the seed to dry out during this entire process. If it doesn't germinate after you take it out of the fridge next spring, it is probably hopeless. You can also check the seed for viability by cutting a few seeds open and checking the kernel. It should be hard and cream colored, but not dry and chalky, or dark, or mushy. A concave cutter is good for cutting them open.

HI Brent
I have here on my desk 2 leaves and 4 seeds of "Acer sempervirens* or maple form Creta it is a sort of trident maple small leaves quite hard like bay leaves it is making a lot of seeds actually ( May in Europe Geneva botanic garden ) I made a scan if you wish to see it It only looses partially the leaves during the cold winther here When should I collect seeds? september? they seems quite in advance for the season.. and making cuttings ? is june the best season for ? thanks for your feed back Theo Brent Walston wrote: At 02:07 PM 5/4/03 -0500, Neal Ross wrote: Last summer I purchased some Trident maple and Amur Maple seeds from Angelgrove Seed Co.

My season for collecting Maple seeds is as soon as the wings start to
turn brown. This can be as early as late July in my part of the world, depending on species and weather. I take cuttings as the new shoots harden. Cheers Kev Bailey I have here on my desk 2 leaves and 4 seeds of "Acer sempervirens* or maple form Creta it is a sort of trident maple small leaves quite hard like bay leaves it is making a lot of seeds actually ( May in Europe Geneva botanic garden ) I made a scan if you wish to see it It only looses partially the leaves during the cold winther here When should I collect seeds? september? they seems quite in advance for the season.. and making cuttings ? is june the best season for ? thanks for your feed back Theo --- Outgoing mail is certified Virus Free.

Acer species seem to fall into two categories with regard to seed, spring ripening and fall ripening. Spring ripening seed forms from flowers that develop in very early spring as the leaves emerge. The seed develops immediately and is ripe in about a month or two. You can tell the seed is ripe because the seed will begin to dry a bit and perhaps start falling from the tree. This seed must be soaked and planted immediately at 70F or above. Your tree probably falls into this category. If you want to play it safe, divide the seed in half. Plant half when you think it is ripe. Leave the rest on the tree. When it starts falling from the tree by itself, soak it and put it in the refrigerator until next spring.

A. sempervirens is a valid name, my books on seed just don't cover it. It is listed in Maples of the World, but there is no information on seed ripening or pretreatment.
