These are counts of records collected
somewhere in the region, which is the resolution of the
evidence: the map above shows where inside it. A region with
3 records is not the same claim as one with three
hundred, so the count travels with the region. A region missing from
this list means nobody has recorded it there, which is not the same as
the plant being absent. Records within 900 m of a
border count for neither side, because the border is not drawn finely
enough to say which one they are on.

Documented animals No animal relationships are documented for this species in our sources. That is a gap in the catalogue, not evidence that nothing uses it.
Also worth knowing Safety Toxicity not assessed, absence of a warning is not a guarantee of safety
Buying it About $25–$50 per plant (estimate), usually from a native-plant nursery. Estimate (shrub default); AB retail as of 2026
