The nomenclature of ACER is based on the book 'Maples of the World' by D.M. van Gelderen, Dr. H.J. Oterdoom en Dr. P.C. de Jong. This book is considered to be the major reference of the genus Acer for the next decades. 458 pages, more than 200 colour pictures and hundreds of line drawings make up this magnificent book.

ACER PALMATUM CULTIVARS:

The collection of Acer palmatum has been enlarged significantly in the last years. New contacts in Japan, Korea and the USA provided us with several dozen new cultivars. For the time being these new varieties will not be available, we first have to grow some stock, which takes a few years. We want them to be in the catalogue however, all marked with B/L, meaning little stock available. You can see these plants in our nursery, but they are not always available for sale!

The spelling of the Japanese cultivar names have in several cases changed to bring them in conformity with the latest views in this area. These names now mean something in Japanese. For much more information see the new book 'Maples for Gardens, A Color Encyclopedia' by D.M.van Gelderen and C.J.van Gelderen, which was published in the autumn of 1999 and unfortunately recently sold out.

Most varieties of Acer palmatum are grown in 3-litre containers, these are listed in this catalogue with POT 3 litres. These are almost always 2-year old grafts, sometimes 1 year old. The exact sizes of these plants are not important for the calculation of the prices. Some more common varieties are also available in larger sizes, these are mentioned. Sometimes of other varieties larger sizes are also available, prices upon request or see the on-line plant shop where these are also shown with their respective prices.
