At the edge of the trail, large ivy flowers parade on the cliff. Their flowering lasts from September to October and fruiting occurs in late winter, early spring. The Ivy flower therefore presents a reversed phenological cycle compared to plants. Its flowers are among the last to provide pollen for bees. A bee is directly related to the ivy; Ivy bees (Colletes hederae). You can see it flying until early November if the weather is mild and lenient.
