[citation needed] Evergreens have generally a larger fraction of total plant biomass present as leaves (LMF),[5] but they often have a lower rate of photosynthesis.
Additionally, they usually have hard leaves and have an excellent water economy due to scarce resources in the area in which they reside.
[citation needed] In Rhododendron, a genus with many broadleaf evergreens, several species grow in mature forests but are usually found on highly acidic soil where the nutrients are less available to plants.
[citation needed] In temperate climates, evergreens can reinforce their own survival; evergreen leaf and needle litter has a higher carbon–nitrogen ratio than deciduous leaf litter, contributing to a higher soil acidity and lower soil nitrogen content.
This is the case with Mediterranean evergreen seedlings, which have unique C and N storages that allow stored resources to determine fast growth within the species, limiting competition and bolstering survival.
In months where most other plants are dormant, evergreens with their sturdy structure, and vibrant foliage are popular choices to beautify a landscape.
Additionally, evergreens can serve as a windbreak, stopping heat loss from buildings during cold months when placed on the northwest side of a structure.
