Dissectum

Dissectum

Dissectum actually is a group in the Palmatum species, but it is so different from the other Palmatums that I'm making it a separate section. Dissectums are also known as lace leaf or cut leaf. Leaf lobes are deeply divided and deeply dissected into sublobes. The trees are generally weeping spreaders, but a few are semi-upright to upright.

Dwarf

Dwarf

Dwarf Japanese Maples are also actually a group in the Palmatum species but I'm giving it its own section here, due to its unique use in smaller areas and gardens.They have various leaf colors, forms and habits. All Dwarf Japanese Maple trees are under six feet at maturity, with some as small as twelve inches. Many have a compact bushy look.

Other hardy Asian maples

Other hardy Asian maples

These include Shirasawnum, Japonicum, Griseum, Sieboldianum and Pseudosieboldianum. All are hardy to zone 5 or even zone 4. Don't forget that the zone charts have changed so check out the new chart from the USDA.  You may very well be in a warmer zone than before. These are the best cultivars for those at the edge of JM growing areas. They will give you the best chance for success in your cooler climate.
Conifers

Conifers

Many call them just "evergreens' but they encompass a huge number of specific culitvars.... literally thousands and thousands. There are  hundreds of new cultivars that are introduced each year each year. I specialize in dwarf cultivars which like JM's can be super small or just smaller than "large". Most of my cultivars are not commercially available. I have hand picked a small assortment of very cool conifers that will do well in Midwestern weather and soil conditions, and many other more forgiving  areas of the country. The conifers that are in one gal containers sell in the $45-$50 (not including shipping) range, and can be shipped inexpensively or added to any JM order with little or no extra shipping cost.
Conifers are probably the best all around companion plant/tree for Japanese maples .. they compliment each other in a way few other trees or plants do .If you are buying Japanese maples you should take a close look at and include a few of these cultivars in your order as well.
