Maidenhair Tree ‘Blagon’ · Ginkgo biloba ‘Blagon’

'Blagon' holds a distinctly columnar habit (Habitusform), reaching roughly 12 to 15 metres in height against only 3 to 5 metres of spread, with a dense, well-structured crown. This narrow profile suits it to confined street pits, avenue alignments, and contemporary courtyards where lateral room is constrained but vertical presence is wanted. As a grafted male selection it carries no fruiting, removing the malodorous seed litter of female Ginkgo.

Winter hardiness (Winterhärte) is not a constraint for this species. Ginkgo biloba is reliably hardy well below minus 25 degrees Celsius and performs across every German climate region, from the mild Oberrheingraben (Upper Rhine valley) to the colder continental sites east of the Elbe and the voralpenland (pre-Alpine foothills). There is no northern or eastern limit to flag, and no first-winter protection regime to specify, which distinguishes it from the Mediterranean taxa that share this catalogue.

Its street tree suitability (Stadtbaumeignung) rests on demonstrable mechanisms: tolerance of compacted soils and confined root volumes, moderate de-icing salt tolerance, and resilience to air pollution and summer heat. The species held its canopy through the dry summers of recent years, supporting its standing as a Zukunftsbaum and its presence on the GALK-Straßenbaumliste (the definitive German street tree recommendation list maintained by municipal parks departments).

Site requirements (Standortansprüche) are undemanding provided drainage is sound: it performs on free-draining loams, sands, and calcareous substrates to high pH, but resents waterlogging. Full sun is needed for crown density and the strongest autumn display.

The dichotomously veined, fan-shaped foliage emerges light green and turns an even, intense golden yellow in autumn, a defined specification criterion for public space. Ginkgo carries no significant pest or pathogen pressure, making 'Blagon' a structurally reliable choice where disease exposure must be minimised. Slow to moderate growth keeps the crown disciplined under typical German pruning regimes.
