Hibiscus


I’ve found an interesting plant in multiple locations in our community of Lincoln Hills (Placer County).

In our Placer County, Lincoln Hills, 55+ community we have 500 acres of open space and preserved areas, most with meandering streams, and a few ponds. These don’t belong to our community, but are administered by the Wildlife Heritage Foundation.


Alongside moist areas (close to streams or ponds) from late summer to late fall, we can find a white hibiscus in bloom. On one secluded location, these have been blooming in October and November. This week (Nov. 9-11) our low temperatures were -2 Celsius or 28 Fahrenheit, so that may slow down blooming. The last photo with the tape measure was taken Nov. 12, 2020, and many buds were ready to open.

On one well known wildflower photographer’s website (he’s a member of this Facebook page), a similar-appearing hibiscus was discussed, and a name proposed – Woolly-rose-mallow, Hibiscus lasiocarpos var. occidentalis. I looked it up in iNaturalist, and this appears to be correct. I also submitted photos and GPS information to iNaturalist.


I had been communicating with UC Davis folks to find out whether they are cultivated plants which naturalized and appear similar or are the CNPS Rare Plant rank 1B.2. I don’t have an answer yet.
