There is a large movement now to name new varieities and reclassify old ones (Green Trompenberg from palmatum to shirasawanum to name one). The same stands with 'Herbsfeuer', a green palmatum grown in vacinity to a vine maple does not mean a hybridization occurred. Keep in mind that when you read that one maple is a hybrid between two species, thereby what is called an interspecific hybrid, you are reading the assumptions of those that have viewed the characteristics of the plant and have 'assumed' it is a hybrid.įor example, because Acer palmatum 'Trompenberg' was grown in proximity to Acer shirasawanum 'Palmatifolium' and a resulting seedling germinates in the vacinity looking somewhat like a red 'Palmatafolium' says nothing about the actuality of a hybridization occurring.
