These are only a few recommendations. Other deciduous trees may be allowed. Contact the City Forester with questions.
Deciduous means falling off at maturity or tending to fall off (deriving from the Latin verb decido, "fall off") and is typically used in reference to trees or shrubs that lose their leaves seasonally and to the shedding of other plant structures such as petals after flowering or fruit when ripe.
In a more specific sense deciduous means the dropping of a part that is no longer needed, or falling away after its purpose is finished. In plants it is the result of natural processes.
Deciduous has a similar meaning when referring to animal parts such as deciduous antlers in deer, or deciduous teeth, also known as baby teeth, in some mammals (including human children).
In botany, an evergreen plant is a plant having leaves all year round. This contrasts with deciduous plants, which completely lose their foliage for part of the year.
Leaf persistence in evergreen plants may vary from a few months (with new leaves constantly being grown as old ones shed), to several decades (over thirty years in Great Basin Bristlecone Pine Pinus longaeva).
