Untangling the maze of strange names: a very general guide for Horticulture Division entry cards. Please refer to resource books or web sites for more specific information.
Using Rhododendron maximum or the native
Rosebay Rhododendron as an example:
(underlining shows example)
Rule 1: The
botanical name should have two words - the genus and the species.
The botanical name MUST
always have the GENUS first:
Rhododendron maximum
Rule 2: Those two words may include: 1. Species only (Rhododendron maximum)
2. Subdivision of the Species:
A. Species & Variety
Rhododendron maximum var. roseum
B. Species & Cultivar
Rhododendron
maximum ‘Midsummer’
C. Cultivar only:
Rhododendron
‘Pride’s Pink’
Definitions:
GENUS (pl.
genera) - Always a noun. A group of
plants closely related and including one or more species. The first word in a plant’s botanical name,
in Latin and always capitalized.
SPECIES - (s
& pl) - The particular member of the genus, the second half of a botanical
name, in Latin and in lower case. When
the species is not known, sp. may be written after the genus, i.e. Rhododendron
sp.
SUBDIVISIONS:
VARIETIES: Varieties are found in nature; the word is
Latin-like and you should use reliable references to determine varieties.
CULTIVAR: Plants cultivated by man for a particular
set of desirable characteristics, coming from a hybrid or a variant. The cultivar name uses not more than 3 modern
words, is always capitalized and set in single quotes.
When a cultivar name is
unknown, ‘cv’ may be written in place of the cultivar name, i.e. Rhododendron
‘cv’.
COMMON NAMES:
Common names are desirable, but not
necessary. Capitalization if optional.
Botanical name: Rhododendron
maximum
Common name: Rosebay Rhododendron
FAMILY:
One or more genera which are more or
less alike, especially in flower, fruit or a combination of these and other
characteristics.
Rhododendron belongs to the family
Ericacaea
HYBRID:
A plant resulting from a cross
between two different species or two genera.
The use of an “x” preceding a word
is a flag saying that plant is a hybrid.
A hybrid may be between two genera or
between two species and given a species name with an “x” before the
species name.
ADDITIONAL PLANT
CLASSIFICATIONS:
Growth Habit:
Herbaceous - fleshy, soft tissue, dies to the ground in winter
Woody -
maintains above-ground woody parts
Vine - with twining,
clasping or self-clinging growth habit
Tree - with single
central axis, 6 feet or more from the ground
Shrub - with several
stems branched from the ground
Deciduous
- leafless part of the year
Evergreen
- having leaves all year
Hardy - able to withstand low winter
temperatures
Tender - mostly annuals, harmed by low
winter temperatures
Annual
- takes one year to complete
it’s life cycle (seed to seed) and then dies
Biennial - takes two years to complete it’s
life cycle before dying
Perennial
- grows indefinitely year to year
**
Plants may change with the environment.
A hardy plant may be tender in another zone or may only be an annual in
other zones.
