The leaf is composed of 5 lobes. The lobes at the base are well developed, which gives the leaf a sagittate appearance. The blade is shiny dark green. The foliage takes on colors in cold and dry weather.

The question of circumstance…
What is a sagittate leaf?
The vocabulary used by botanists to describe plants is very rich. For leaves alone, you can come across dozens of specific terms.
The word ‘sagittate’ comes from the Latin sagitta which means arrow. A sagittate leaf is a leaf whose blade is shaped like an arrow. Similarly, a leaf whose base is sagittate is a leaf whose base is shaped like an arrow.
Ivy in literature
“Ivy spread, weaving a mantle of green over the ruins, bringing a hint of life to the desolation.”
