DecidÂuÂous trees from LapÂpen, such as the Tilia (lime), Acer (maple), Fagus sylÂvatÂiÂca (copÂper beech), QuerÂcus (oak) and NysÂsa (tupeÂlo gum), offer the onlookÂer a senÂsaÂtionÂal disÂplay of autumn colours. In turn, othÂer plants bloom attracÂtiveÂly in spring, amongst othÂers the Prunus ‘accoÂlade’, yedoenÂsis or ‘TaiÂhaku’ (JapanÂese cherÂry), togethÂer with a large numÂber of othÂer ornaÂmenÂtal trees.
In sumÂmer they proÂvide shade in the streets, car parks, garÂdens and parks. Such variÂeties with highÂly develÂoped crowns and high growth, includÂing the LiriÂoÂdenÂdron (tulip tree), are parÂticÂuÂlarÂly suitÂed as free-standÂing soliÂtary trees for parks and avenues.
The acer plaÂtanoides ‘Columnare Dila’ (columÂnar NorÂway maple), on the othÂer hand, is freÂquentÂly plantÂed in narÂrow streets and small parks. The frost-hardy and wind-resisÂtant, but someÂwhat heat-senÂsiÂtive Acer freeÂmanii ‘ArmÂstrong’ (red maple), one of the 150 sub-species of the acer (maple), is also suitÂable for plantÂiÂng in conÂfined spaces and narÂrow streets. Its bark is silÂver-grey and it blooms before bud burst in March with beauÂtiÂful orange-red panicles.
But it’s not only the growth and colours that are imporÂtant when selectÂing the right tree. The cliÂmatÂic and soil conÂdiÂtions at the future plantÂiÂng site also play a key role. For instance, the straightÂforÂward Alnus (alder) places no parÂticÂuÂlar demands on the soil. It thrives on nutriÂent-poor, dry soils while simulÂtaÂneÂousÂly copÂing with a high levÂel of soil saturation.
The BetuÂla (birch) also prefers a sunÂny locaÂtion, but is still capaÂble of tolÂerÂatÂing almost all soil conÂdiÂtions. The QuerÂcus (oak), in conÂtrast, loves rich, deep soil, with at least some clay in the lowÂer levÂels of the soil.
If the soil and cliÂmatÂic conÂdiÂtions are good, real giants can develÂop from the trees grown by LapÂpen: alongÂside QuerÂcus (oak), Fagus (beech) and Ulmus (elm), the Acer (maple) can also grow up to 30 m tall. If the tree stands in an unreÂstrictÂed space a magÂnifÂiÂcent crown will grow. The deep-reachÂing roots and soil-improvÂing leaves of the Acer (maple) mean that it is optiÂmalÂly suitÂed to derelict land.
Future trees can also be found among the tree nursery’s decidÂuÂous shrubs. These are charÂacÂterised by their growth vigour, life expectanÂcy, and low levÂel of care, harÂdiÂness and resisÂtance to breakÂage. Such trees include the Acer campestre (field maple) in varÂiÂous variÂeties, Celtis ausÂtralis (EuroÂpean netÂtle tree), Acer buergÂeÂriÂanum (triÂdent maple), FraxÂiÂnus americana(white ash), Acer monspessulanum(French maple), QuerÂcus cerÂris (Turkey oak), Ostrya carpiniÂfoÂlia (hop hornÂbeam), ZelkoÂva serÂraÂta (JapanÂese zelkoÂva), GledÂitÂsia triÂaÂcanÂthos (honÂey locust ‘SunÂburst’) in varÂiÂous variÂeties, KoelÂreuteria panÂicÂuÂlaÂta (pride of India) and the FraxÂiÂnus ornus (manÂna ash).
AnothÂer plant in the tree nursery’s comÂpreÂhenÂsive range is the Tilia henÂryana (Henry’s lime). This proÂduces parÂticÂuÂlarÂly rich necÂtar and pollen and thereÂfore freÂquentÂly attracts honÂey bees. The bee pasÂtures proÂvide reliÂable staÂbilÂiÂsaÂtion of slopes and inland dunes.
