A plant's identity and its geographic origin are
related but different pieces of information.
What is provenance?
Provenance refers to the geographic origin of
plant material. For seed-grown plants, this can
include where the original seed was collected.
For other propagation methods, the source of
the original material may also be relevant.
Knowing provenance can help buyers evaluate
whether a plant source aligns with the goals
of a locally focused planting or restoration
project.
What is an ecotype?
An ecotype is a population associated with
particular environmental conditions and
potentially possessing inherited characteristics
associated with those conditions.
The term is more specific than simply saying
a plant is native to a state or broad region.
It concerns population-level variation rather
than just the species name.
Why does the distinction matter?
Two plants identified as the same species may
originate from different geographic populations.
A nursery's regional specialization does not,
by itself, establish the provenance of every
plant in its catalog.
If local provenance or ecotype matters to your
project, request the nursery's specific source
information rather than relying on general
marketing descriptions.
