Plants suitable for the Inland Empire are provided in the lists for each type of plant (trees, shrubs, etc.). Selected plants are featured with photos and descriptions. Take a gander and get inspired! Click on each photo to get detailed information (In progress). 

If you believe the information on the plant lists is incorrect, or you have a suggestion, please let us know using the Contact form under About Us.

The plant lists are extensive. They include species that are very common to very uncommon. All are sorted by both botanical names and common names. The longer lists (trees, shrubs, and perennials) have separate lists sorted by botanical names and common names. There are some abbreviations in the lists:

  • d - Deciduous. Plants that lose their leaves due to seasonal dormancy or water-restrictive dormancy.
  • de - Some species will lose their leaves for only a short time, and only if particular environmental conditions exist.
  • e - Evergreen
  • N - Indicates California native species
  • spp., cvs. - Multiple species or cultivars
  • ssp. - Subspecies
  • var. - Variety

Some species have varieties or cultivars that can be wildly different in size from the original species. An example is Cupressus sempervirens 'Tiny Tower.' It only grows to a height of 8 feet while the original species grows to over 70 feet. There are thousands of plant varieties and cultivars; too many to have in our lists. If you see a plant name followed by "spp." or "cvs." you will know there are varieties and cultivars that are likely different from the original species. The best way to find out about these is to do an internet search "Varieties or cultivars of [botanical name]." Or inquire at your local nursery.

 

Plant Names

Did you notice the lists are alphabetized by funny names. Why? Those funny names are botanical names. Each plant species has a unique botanical name. If we used common names, confusion would result because many common names are associated with a number of completely different plant species.  Take, for example "Mimosa." Do an internet search of mimosa and you will find a variety of plants and even a few cocktails! However, search for Albizia julibrissin and you will find a very specific plant with one of several common names being of mimosa.

So here is a little science lesson... Botanical names are basically made up of two names: the genus name and the species name. Let's use roses as an example.  The botanical name for roses is Rosa (always written capitalized). There is a specific plant or species of rose called Lady Banks' rose. The botanical species name for this rose is banksiae (always written in lower case). Hence, the botanical name for Lady Banks' Rose is Rosa banksiae. But what about cultivars, hybrids, and varieties? 

  • Cultivar - a man-made species created by hybridization, mutation, or selection for desirable characteristics light color, fragrance, growth habit, etc.  A cultivar name is denoted with single quotes: Rosa 'Double Delight' 
  • Hybrid - an offspring resulting from the breeding of two genetically distinct species. An example of breeding two distinct genera is the cross between Hedera helix and Fatsia japonica. It is written as xFatshedera lizei where the "x" is a multiplication sign. An example of breeding between two distinct species is the cross between Plantanus orientalis and Plantanus occidentalis, thus forming Plantanus xacerifolia, the London plane tree. Often, for simplicity's sake, the "x" is removed from the name. 
  • Variety - a subspecies that is a naturally occurring variation within a species. It is denoted as a word or words, typically in Latin, following the abbreviation "var." A common example is Pittosporum tobira var. variegata.  You will often see a common error of "var." left out of the name.
