Here are twelve native
Asclepias species (milkweeds), displayed in What Grows Here? starting near Redding,
each shown on the map with its own colored icon.
What Grows Here? (WGH) can display a thorough plant list for a chosen area of the state
in several formats.
Select the area by moving and zooming the map, or draw a polygon,
or choose a polygon from a background layer, such as the
boundary of a State Park.
What Grows Here? Wizard
is available to help find a location by name in California.
Starting from the wizard, you will end up in the map application.
WGH provides some interesting ways to visualize plant data --
for instance, displaying the locations of several plants
on the map at the same time, assigning a different icon
to each plant. A set of plant - icon assignments is called a palette.
The various mapping applications can show a number
of background layers, or polygon sets.
Latest additions include
(all derived from data from the Prism Climate Group)
and various soil factors (eg. pH, Salinity)
from the NRCS SSURGO database.
to transform photos of plants into observation reports.
If a photo is geotagged, the software will pick up
the location; otherwise, you can set the location on a map
when you edit the record in
Plant Observation Entry.
The entry applications include
the ability to add a line
or polygon to a record.
Use it to describe the spatial extent of an plant population,
or the area covered by a survey or checklist.
For example, Jerry Baker added this polygon
to describe the extent of a patch of
Astragalus Brauntonii, Baunton's milk vetch, in Los Angeles Co.

point showing through, which is a previous record of the same plant.)
The Great Places
places in California which are particularly good for viewing native plants.
The search page now shows the number of acres and the density
(native species per acre) for each place.
If you have already made a bunch of observations with photos
in a particular area, then that area would probably make
an excellent Great Place.
The places can include both wild locations and gardens where natives have been planted.
There are three component applications: a home/search page, a page about a particular place, and an editor for adding a new place page.
Use this application to search for native plants likely to grow well at
your chosen location. Click on the map to indicate the location, press SEARCH,
and the results will show commercially available native plants
appropriate to the elevation, climate and soil of the chosen site.
When you are seeing a good plant list, you can download it as a spreadsheet or email
it to yourself, and then forward it to native plant nurseries
to find out what they have in stock.
In version 0.72, the TOOLS menu includes a Download spreadsheet link.
Here is an example:
From the Taxon Report page for the plant, click on the link to go to the Location Suitability page.
Click on the map to indicate the location of your garden. Scan the third column, "LOCATION VALUES", to see if there are any pink warnings indicating location values outside of the tolerances of the plant.
If there are warnings, you may want to try a different plant.
If there are NO warnings, then this plant is compatible with the conditions at your location. As a further sanity check, press
SEARCH in the map area
to find out if this plant has been reported growing wild, close to your location. If it does grow close by, this is a good sign that it could do well in your yard.

discussion on CNPLX.)
The Taxon Report page is now mobile friendly.
If you view it on a narrow width device such as a phone or tablet, it will adapt to

The map on the Taxon Report page indicates
plant presence by means of points and quads (instead
of by colored counties).
The map shows elevation in colors inspired by a
classic USGS map.

(climate and soil)
PlantID.net is a new website which offers help in identifying
wild plants in Calfornia.
It has a really good search feature: from the top page, you can enter any of the following:
county plant type (eg. "shrub") flower shape flower color leaf shape
and the site will find the matching plants.
The site has lots of big photos, some of them annotated.
This site is the brainchild of Bruce Homer-Smith, and more useful features are coming.
For instance, here is an article on
The Calflora Taxon Report page also has a link to the PlantID.net
page for the same plant, for those plants now covered by PlantID.net.
The link is in the More Information section; for instance
This page shows the climate and soil tolerances
of a plant (the conditions under which the plant will grow).

The climate factor,
helps to distinguish very hot places from moderately hot places.
Also, the factor fomerly known as Warm Months has been
recalculated and re-named
Climate factors are mostly based on data from the
Prism Climate Group at Oregon State University.
Taken together, they describe the local climate of various locations in California.
By extension, the climate tolerances of a particular plant
can be inferred from values of the factors at locations
where the plant is known to grow.
The elevation values of all observation records
were updated, in meters, by referencing the point location against
a digital elevation model.
Also, whenever you edit an observation record

you can see the elevation of the new location immediately by pressing
The application will also update
the elevation value automatically when you save the record.
The elevation value comes from the Google Maps Elevation API.
Accurate elevation values can be important in predicting
where a plant will grow.
The elevation range of each plant was recently derived
by analyzing the elevation values of observations
of that plant. The elevation range in meters is reported on
You can be notified by email whenever new observation records show up in the database.
For instance, you might want to be alerted when any new observation
of a certain plant shows up in a certain area.
To set up an alert, first use

Then open TOOLS / SAVED SEARCHES, and save your search by name.
Then go to

table of AVAILABLE SEARCHES. Click on that search, and choose whether
you want the alert every week or every month.
Here is an example of an alert, sent on September 1, 2016, for
Observations of Mimulus species with photos:
