Bol Park Revegetation Project: Description of Native Plants
Description of what has been planted and what is being considered or sought
as part of the
Bol Park Revegetation Project.
Evolving Page: Goals
This page does not yet reflect our numerous acquisitions
since late spring 1997.
We hope to go to a more formal database for the information listed here
because there are many partial, often conflicting, sources of information
and a textual listing makes it too easy to lose track.
Wildlife supported covers only special/notable aspects.
Unfortunately, many of the reference materials do not identify
which aspect of the plant is important to the named animal.
This information has been culled from multiple sources,
with attempts to localize it.
Some sizes may be typical
and others may be the normal range for "normal" environment
and others still may be the absolute range for all environments.
For example, some trees grow significantly larger when given summer water.
Unfortunately, most of the reference materials do not identify which
of these situations they are presenting.

Propagation:
Note: fast growing
Note: The Water District's own manual on plants states
that this tree is
poisonous to honeybees (Apies mellifera L.)
:
Do not plant this tree near bee-pollinated agricultural
crops or wherever it could cause similar problems.
This tree's pollen also makes the bee's sting more
potent
(Source: last paragraph of Hymenopterism section in Urban Entomology by Walter Ebeling).
Note that this warning refers specificly to honeybees,
and is silent on other species of bees.
Other documents suggest that honeybees are particularly
susceptible to this problem,
but that it does affect other bees to lesser extents.
Without consulting with the BPA,
they approved a change that substituted in this tree.
The BPA was able to get half of them removed,
but the other half remain --
in a natural habitat that was designed
to support and depend upon bees.
On the other hand, there already are a number of these trees
present from before the construction project.

VanHoutte's Columbine (A. eximia)
Height: 2-3
, Breadth:
Bloom: scarlet, May-August
Fruit/Seeds:
Note:
Several books note that A. eximia tends to produce
few volunteers from seed -
especially in relationship to A. formosa -
which matches my personal experience
(although I have had no problem starting plants
from seeds collected from existing plants in my garden).
May be more desirable in garden than A. formosa because
it blooms all summer with large flowers and
has attractive wide branching structure.
Western Columbine, Red Columbine (A. formosa)

Pacific Coast Irises
Note: the irises in this group freely hybridize in the wild.
Thus, at various native plant sales, you will see specimens
classified only as "Pacific Coast Hybrid" (PCH)
Personal observation:
I would treat the classifications with a bit of skepticism,
treating them more like "bulges" on a continuum
rather than truly distinct species.
Coast Iris, Long-petaled Iris (I. longipetala) - classified by some to be the same as Western Blue Flag Iris or Rocky Mountain Iris (I. missouriensis)
Aside:
It is called I. missouriensis when found
in the interior mountains (Sierras, Rocky Mts, ...)
(Yellow Pine or Red Fir Forests;
at elevations of above 3000 feet),
and I. longipetala when found at lower elevations
near the coast,
hence the common names.
Slender-tubed Iris (I. fernaldii)
Douglas Iris (I. douglasiana)
Lily (Lilium)
Humboldt Lily (L. humboldtii)
Leopard Lily (L. pardalinum)
Cascade Lily, Washington Lily (L. washington)
Blue-eyed Grass (Sisyrinchium bellum)
Wake Robin (Trillium ovatum)
Annuals / Wildflowers
Advice:
When a plant is labelled as larval food,
it means that the larval form of the butterfly eats parts of the plant.
Use these plants in larger groups:
(1)
the damage is spread over more plants,
(2)
with many plants overlapping, the damage is less visible, and
(3)
more food for more larvae produces more butterflies.
Rocket Larkspur (Delphinium ajacis) (non-native, but included in various "California Wildflower" mixes)
Height: 1-2
, Breadth:
Bloom: blue-violet
Fruit/Seeds:
Animals supported:
Tansy Mustard (Descurainia pinnata)
Turkey Mullein/Dove Weed (Eremocarpus setigerus)
California Poppy (Eschscholzia californica)
Height: 1-2
, Breadth:
Bloom: yellow to dark gold
Fruit/Seeds:
Animals supported: Nectar: bees; seeds: doves, sparrows, meadowlarks, ...
Note: Actually a perennial.
With some summer water will bloom repeatedly
and come back the next year.
Root goes very deep searching for water
(personal experience: over 4 feet long),
so best to plant in fall to give roots chance to develop.
After setting seed, the stalks may die back to the ground
or near the ground, but new growth appears if/when there
is adequate water (ground water or provided).
Suggestion:
Plant large group of California Poppies,
not just for color, but for wildlife.
On a still day, the bees will cause the flowers to bob
as if there was a gentle wind.
The bees force their way into just-opening flowers,
and lay on their sides and madly spin around to collect as
much pollen as they can.
After the seed pods open, doves and sparrows will seem to
be permanent diners, not just occasional visitors.
Bee Food (Phacelia tanacetifolia)
Height: 1-4
, Breadth:
Bloom:
Fruit/Seeds:
Animals supported: nectar: bees, butterflies
Note: very effective attractor for bees, often recommended to interplant it with crops

Height: 2
, Breadth:
Bloom:
Fruit/Seeds:
Animals supported:
Problem: snails love it.
For residential landscaping,
many gardening books recommend growing it in a hanging pot.
