The
Linden family is characterized by heart shaped leaves,
graceful shady crowns and small golden flowers that are
know for fragrance. Lindens are one of the most
attractive ornamental trees because of their symmetrical
growth habit. They take a couple of years to set
down root after transplanting and then grow at a moderate
to fast rate once they are established.
Lindens prefer to grow on moist, fertile soils that are
well drained and sufficiently aerated. The
homeowner or city crew can provide optimum conditions for
Lindens by a regular maintenance program that includes
watering, fertilizing, pruning and aeration.
Lindens that have been planted on the harsh urban sites
tend to lose their vigour and die prematurely.
Sites that are not suitable for Lindens include the heavy
soils that become compacted by urban activity, draughty
soils that do not retain moisture or fertilizer,
locations where winter salt spray is prevalent and highly
exposed areas where wind and sun penetrate the tree.
Lindens have the potential to be used more extensively as
a landscape tree throughout the prairies. They are
becoming more available and can serve as an alternative
to the widely used ash (Fraxinus). The main
Lindens grown on the prairies are presented below. All of these lindens do well in the
northern prairies or Parkland area. In the dry
south-western region of the prairies, American and
Dropmore Linden have performed best.
