Specific Leaf Area and Specific Sprout Area for accrescence were clearly different
(Table 4; Figs. 3 and 4). North produces a Specific Leaf Area of 126 cm2/g, South of 101 cm2/g, and a Specific Sprout Area of 11 cm2/g, south of 8 cm2/g. Investigations by Schröder et al. (2009) and investigations by Hoflacher and Bauer (1982) also showed the tendency to a higher Specific Leaf Area of H. helix sp. on the shady side. Bartfelder and Köhler (1987) found a similar Specific Leaf Area for a north side with H. helix (Table 5).
