Magnolia grandiflora ‘TMGH’, trade name Alta is one of the 21 new plants that are officially nominated for the Innovert award of the upcoming international trade fair Salon du Végétal which will be held February 19-20 in Angers, France. Young plant producer La Forêt Jeunes Plants submits this new magnolia to the Innovert competition.
History goes decades back
Actually, the history of Magnolia Alta goes several decades back. It was discovered as a so-called chance seedling in a production field of Future Trees in Statesboro, Georgia (US). US Patent was granted in 2000, with Thomas Julian Strickland mentioned as inventor and Tree Introductions as owner. Tree Introductions describes Alta as a cultivar with a naturally columnar habit, with dense, glossy foliage. “This dense growth not only means less pruning for the grower, but also a maintained appearance in the landscape.” Alta should also have a more fibrous root system than many other magnolias, meaning less die back after planting.
Problems in propagation
In the US a number of nurseries have Magnolia grandiflora ‘TMGH’ in their portfolio. It is also introduced in Europe by royalty management agency Plantipp/Concept Plants. According to the website of this agency there are also in Europe several licensed growers. However, Plantipp co-owner Peter Rijssen refers to the problems in the propagation of Alta in the past seven years. These problems should be solved now.
He emphasizes that it takes many, many years to develop Alta into a street tree. In trials this cultivar showed being extremely winter hardy. Rijssen shows himself happy with the French introduction of this magnolia.
