Glossary: Descriptors Used On Plants Lists
PRELIMINARY, web page under construction, February 12, 2019
The descriptors that are used on the lists of recommended plants for Sonoma County are defined below.
Note: The letters that indicate the applicable descriptions were chosen to be easy to remember, but that led to using the same letter for two different descriptors. To distinguish between the two, lower case is used for descriptors of size (for example, s indicates small, S indicates full sun).
"spp" in the name refer to all species within the named genus.
"cvs" in the name refer to cultivars within the named species.
Plant lists are organized by plant type: Trees, Shrubs, Ground Covers, Vines, Perennials, Succulents, Grasses and Grass-Like, and Ferns. Plants identified here as Ground Covers may be identified by nurseries or others as shrubs or sub-shrubs or perennials.
Plant Size, by Type
|Plant Size||Tree||Shrub||Perennial, Grasses, Succulents, Ferns||Ground Covers|
|s = Small||15-20 feet high||3 feet or less high||1 foot or less high||3 feet or less wide|
|m = Medium||20-40 feet high||3-6 feet high||1-3 feet high||3 to 6 feet wide|
|g = Large||over 40 feet high||6-15 feet high||over 3 feet high||over 6 feet wide|
Water requirement indicators are based on the WUCOLS (Water Use Classification of Landscape Species) list. More information is available on the WUCOLS website.
|H = high
||Require the greatest amount of water during the summer months to maintain acceptable health, appearance, and growth
|M = moderate
||Need lesser amounts of water. Tolerate some drying of the top few inches of soil; may need water every week to ten days away from the coast or every two weeks in areas with maritime influence.
|L = low
||Perform well with relatively small amounts of irrigation water. Give deep soaking every three to four weeks.
|V = very low||Need no irrigation except during years of below average rainfall for the region. Give deep soaking once or twice during the hottest and driest months of the year|
S = full sun
A = afternoon shade
P = partial shade
F = full shade
For items in the plant list that refer to all species within the named genus (indicated by "spp" in the name), a given quality may not apply to all of the species in that genus. See the comments for that item.
