ACER dissectum group

Perhaps the archetypal Japanese Maple, these have lovely finely divided fern-like leaves and (with the exception of 'Seiryu') develop a mushroom like habit. Choose from a wide range of colours - green or rich purple for a sunny site or cream margined and variegated in shade. Watch out for summer drought and avoid exposure. The perfect complement to a pond.

It can be useful to gain initial height by training a strong shoot up a cane. Even if you want a weeping plant, this height will establish a framework for it weep from.  

Please Note: Technically, few of these cultivars should be listed with "dissectum" in their name. However, to make it easier to see which plants have this distinctive leaf-type, I have included them here in this manner for ease of use only. 


ACER palmatum dissectum 'Ao shidare'
The feathery green leaves are typical of the dissectum group, as is the gently weeping "mushroom-like" habit. The yellow autumn colour is excellent.

ACER palmatum dissectum 'Atropurpureum' 
These are fantastic specimens with wonderful architectural, almost quirky habits. Others are more symmetrical. They have fine purple deeply divided leaves, turning red in autumn. Their attraction is not limited to pot culture; they are as perfectly useable in the garden as any other Acer.

ACER palmatum dissectum 'Autumn Fire'
Arising as a chance seedling in Oregon in 1979, this pretty cultivar was not actually named until 1996. It is less pendulous than the usual mushroom shaped dissectum, though still quite broad. Pink edged, pale green new growth matures to mid green in summer before taking on spectacular red autumn colour. Deeply toothed substantial leaves make this a really rewarding plant to grow. Expect 2m by a greater width. See it planted at the top of our Woodland Quarry Garden.

ACER palmatum dissectum 'Baldsmith' 
A recently introduced dissectum from America. The leaf shape and habit is familiar, being typical of the dissectum group, but the greeny-orange colour is quite distinct. Yellow autumn colours. A. palmatum dissectum 'Watnong' is very similar, if not the same.

ACER palmatum dissectum 'Barrie Bergman' 
A recent Australian selection, that is slow growing so perfect for pot or garden. Rusty red-purple summer colour turns orange red in autumn. This cultivar stood out for me last summer - they looked fantastic and kept their colour well under difficult weather conditions.


ACER palmatum dissectum 'Benishidare Tricolour' 

See Acer palmatum dissectum 'Toyama nishiki'
 

ACER palmatum dissectum 'Berrima Bridge'
This Australian selection is vigorous as a young plant, but not upright. Thus it seems to naturally attain a wonderful quirky and Oh so "Japanese" shape. It really is very distinctive when seen amongst other dissectums. Young growth is green, becoming flushed with red or bronze through the summer, which is actually the other-way round to how most colours develop. Autumn colours are complex shades of orange as the nights draw in.  

ACER palmatum dissectum 'Bewley's Red'
An excellent new Australian cultivar which can almost be described as a purple foliaged equivalent of 'Seiryu' with upright habit as opposed to the usual weeping shape.

ACER palmatum dissectum 'Bronzewing'
More compact than many cultivars, this delightful Australian cultivar forms a tidy, dense mounded shape. Bronze is an excellent colour description for the leaves - not dark enough to be purple, but much more colour than in a green. Primarily yellow autumn colour perhaps with a hint of orange.

ACER palmatum dissectum 'Chantilly Lace'
An American introduction, we have found this recent selection to be extremely vigorous and well behaved as a young plant. The new leaves emerge a coppery red, whilst the exact colour they maintain through the summer will be influenced by light levels; being greener in shade but maintaining richer reddish hues in more light. Golden yellow to crimson autumn colour. Expect the same size, shape and habit that is typical of the group. The photo shows autumn colour. See it planted in our Woodland Quarry Garden.

ACER palmatum dissectum 'Crimson Queen' 
This selection of the purple dissectums is one of the best. The graceful feathery leaves are a persistent deep reddish purple colour. It will also endure periods of high summer temperatures with the minimum of leaf scorch. Vivid scarlet autumn colour. This dense, tidy selection has a greater tendency to form a neat, dense mound. 1m
