Maple Forums on the UBC web-site

The Maple Society Open Science Initiative is please to present a new maple profile from Peter Gregory, with photos from Hugh Angus of Westonbirt Arboretum, Piotr Banaszczak of Rogow Arboretum, and yours truly. The correct name of this maple has been much disputed, and in 2010 when the original text was published in the newsletter was accepted as Acer robustum. Today we believe the species is most properly called Acer anhweiense. I hope you enjoy it!...

After admiring (and coveting) so many gorgeous maples on this forum, I know it seems presumptuous of me to talk about the unusual seedling that popped up in my garden in 2015. It's likely nothing special although I do think it shows some promise . . . Possible parents are Acer palmatum ‘Osakazuki’, 'Bloodgood' and ‘Seiryu’.

JT1 gave me suggestions about how to document its characteristics throughout the growing season which I've been doing since April.
So far, it distinguishes...

Upstart little JM seedling

Rightly or wrongly I have covered the top of the soil of my maple trees in large pots in that black permeable cloth then added slate chips as a means of keeps weeds down..this year I notice that several of the pots with the cloth cover have maple seedlings with various leaf patterns growing through the cloth and up through the slate..how the seeds got under the cloth I don’t know amazing! I have cut the cloth dug them out and potted them up.. not sure how long they take from seedlings to...

Hi all,

I'm from the UK and have recently purchased a Japanese Maple bonsai tree that I am very keen to be able to keep indoors as long as possible. I understand that the winter dormancy period is very important for the long term survival of the tree but I'm hoping someone here would be able to give me some advice about how much if the year I can keep the tree inside if any.

The place where I would like to keep it is at a window with decent light and I could keep the window open to...

Was out picking up some Erythronium bulbs the other days and although I really don't have room, like Snow White, I came across a couple of attractive dwarves that were hard to resist (now up to 42 different maples in a lot half the size of my last one).

Both seem to be newer cultivars to local outlets and don't appear in the usual 10-15 year old maple books, though I saw a thread here discussing at least one of them.

I was wondering what people's experience with these has been, e.g. growth...

I saw an unfamiliar (for me) maple in the pine forest near to Tallinn. I took a photo of the tree and another of the underside of a leaf, merged those together and attached to this message. Could it be Acer heldreichii subsp. trautvetteri?

Never been before OMG this place is special

Time to show the Spring colors for 2019. From bud burst to full Spring colors, all photos are welcome! Please show the Spring evolution of your maples!

My yard is just getting started.

I think these potted plants at a café in the West End are Acer 'Sango-kaku'. Except in one of the pots, there is a trunk that is not as red, and the leaf colour is entirely different - green/red instead of yellow. But all the other details look the same to me, leaf size and margins, red stem colour. So I think they are really the same. Can it be?

Can these all be A. 'Sango-kaku'?

A friend who lives on Beresford street asked for the ID of these trees. I have never identified an Acer x freemanii, but I thought these might be good candidates for that ID. The leaf shape is similar to silver maples, almost as deeply lobed, and the habit looks similar to that tree; the leaf colour is like red maples, but I didn't see any trident-shaped leaves. What do you think? These are in Burnaby, so I don't have a database to check.

My acer palmatum changed colors in Bangkok, it was a big surprise because my house had no autumn.

This is acer mono. My seeds are very fast growing in Bangkok, but I probably didn't see them change color.

Hi,

Does anyone have a photograph of late summer/early autumn new growth on Tsuma gaki?

I picked this tree up yesterday, it needs some real TLC..am pretty sure it’s Tsuma gaki, I saw a Tsuma gaki at a nursery I don’t visit often a year or so ago and am pretty sure it’s the very same tree..but it’s now lost it’s tag..it was a bit of a bargain at £50 given it has a 3+ inch trunk..there is quite a bit of dieback but there are plenty of buds all over so I am hopeful..you will see in the photo...

Hello, my name is Surachai. I am the founder of Maple Growing Group in Thailand. My country is very hot, so it's difficult to grow. I'm happy to meet all friends who love maple. This is my seedling maple. (I'm not good at language)

Just received my 5ltr Ornatum from Ornamental Trees. It looks like a very healthy happy little plant. I'm looking forward to see the colours change.

Hello everyone!

I collected a few different types of acer seeds and was wondering if they all have the same stratification process to germinate as palmatum?

I collected:
Acer Campestre
Acer Monspessulanum
Acer Pseudosieboldianum
Acer Pubinerve
Acer Heldreichii
Acer Shirasawanum var Tenuifolum
Acer Tataricum

The Maple Society Open Science Initiative (OSI) is pleased to present Peter Gregory's Acer davidii Franchet (1886) profile, with photographs by Hugh Angus. Father David's Maple is one of the best known of the Chinese Maples in the West, where its attractive dark green leaves with orange and yellow fall colors, combined with spectacular striped bark, make it a popular addition to many parks and gardens.
