Circle X Ranch

Canyon View Trail

  Date: 4/21/06



        Still very few flowers making an appearance. Actually, the species count is up to a respectable seventy five species, but many are having such a light turnout that it would be easy to miss the few small individuals in bloom. Now that the ceanothus have mostly finishing up it is harder to be generous in rating this trail, but on the other hand the trail is in good condition, is very lush and green, and is a pleasure to hike. Highlights include black sage, windmill pink, rock rose, chia, yellow pincushion, chinese houses, Parry’s phacelia, red-skinned onion, deerweed, California buckwheat, popcorn flower, wild cucumber, both white and purple nightshade, blue larkspur, wishbone bush, common fiddleneck, mustard evening primrose, wooly blue curls, water speedwell, collarless California poppy, globe gilia, California saxifrage, miners lettuce, annual paintbrush, golden yarrow, bush and creek and yellow monkey flowers, canyon sunflower, wild morning glory, blue dicks, virgin’s bower, a couple of early elegant clarkia, and a few California blackberry.  (TV).

Cheeseboro &

Palo Comado Canyons

Various north-end trails

  Date: 4/20/06



        Trails examined included the Albertson Motorway, Palo Comado Canyon Trail, Sheep Corral Trail, Cheeseboro Ridge Trail and Cheeseboro Canyon Trail. Much of the lower section of this unit is literally choked with non-native grasses and weeds but if you get up to the Northern end you are rewarded with some very nice wildflower displays. Some sections of some of the trails are quite good right now, even very good, but overall the quality of the flower display was quite variable from place to place. Be aware that much of this unit was burned in last fall's fires and has not been fully reopened for visitor use. Be sure to read all posted signs to avoid entering closed areas. Some of the burned areas are especially fragile right now.

        The lower end of the Palo Comado Trail and Cheeseboro Canyon Trail and most of the Cheeseboro Ridge Trail were quite disappointing, but as these trails reach their Northern ends we begin to see good numbers of several different species of wildflowers. The vicinity of the intersection of Sheep Corral Trail and Palo Comado Trails was quite good at least until we dropped back down into the depths of the burn. It is interesting to see how some of the burned areas are coming back primarily as non-native weeds, but in other areas the native wildflowers are holding their own. My own curiosity will certainly keep me watching the burned areas as Spring progresses. Similarly, sections of the Albertson Motorway vary considerably, but none as bad as the weed choked lower end of the unit. Highlights include succulent lupine, paintbrush, purple nightshade, blue dick, prickly phlox, mustard evening primrose, popcorn flower, bush monkey flower, yellow monkey flower, black sage, chia, sunflowers, caterpillar phacelia, Parry's phacelia, several different lupines, wild morning glory, datura, wishbone bush, a lot of both white and yellow pincushions, several different lotus, white and twining snapdragons, eucrypta, several different gilias, sections quite dense with star lily, golden yarrow, blue toadflax, fire poppies, several different pinks, fiesta flower, long-beaked filaree, and skullcap. All told over ninety different species in bloom.  (TV)

Circle X Ranch

Mishe Mokwa Loop Trail

  Date: 4/16/06



        The trail was still quite wet from the recent rains but overall in very good condition. As the weather continues to warm up we are beginning to see a larger variety of flowers, but so far still mostly light turnouts of most species, the notable exception being the several species of ceanothus which have all had a banner year. The hoary-leaved ceanothus is well past its peak now but the beautiful hairy-leaved ceanothus is only a bit past its peak and still showing very dense displays of blossoms. Similarly, the dramatic prickly phlox is past its prime but still plentiful. Other highlights include California buckwheat, wild sweet pea, coast gold fields, fuchsia-flowered gooseberry, yellow cress, popcorn flower, morning glory, wild cucumber, golden yarrow, Eastwood manzanita, a few late shooting stars, chia, California collarless poppy, purple nightshade, mustard evening primrose, small evening primrose, gilia, yellow pincushion, skullcap, blue dicks eucrypta, virgin’s bower, Parry’s phacelia, mountain phacelia, miner's lettuce, a few holdout California peony, California saxifrage, a few different lupines, bush monkey flower, woolly blue curls, chaparral current, and blue larkspur. All told about seventy different species in bloom  (TV)

Castro Crest region

Backbone Trail

  Date: 4/13/06



        On 4/13/06 we hiked the Backbone Trail in the Castro Crest region and identified 75 species of flora in bloom, including the grasses and trees. The trail was in good shape along the entire route and the area that burned last fall is starting to recover with lots of chamise sprouting from the old crowns. There were an equal number of yellowish blooms as there were of the whitish, namely 22 each.

        The whites included Calif buckwheat, chamise, popcorn flower, miner's lettuce, big pod ceanothus, bristly jewel flower and bedstraw. There were a few milkmaids as well as Burt's bur chervil, eucrypta, Mountain mahogany, Eastwood manzanita, and virgin's bower. Less commonly seen were white hyacinth and Calif saxifrage. Wild blackberry, windmill pink, wild cucumber, two-tone everlasting, Calif. everlasting, morning glory and cliff aster were also identified.

        Amongst the yellow blooms were hedge mustard, deerweed, golden yarrow, bush sunflower, prickly sow thistle and blow wives. Also present were snake root, London rocket, miniature evening primrose, western yellow cress and bur clover. Other blooms were American winter cress, Johnny jump-up, canyon sunflower, poison oak, pineapple weed, telegraph weed, bush monkey flower, Southern tauschia, large flowered lotus, bush poppy and Chile lotus.

        Amongst the purplish and blue flowers were red stem filaree, black sage, greenbark ceanothus,  purple night shade, wooly blue curls, dove lupine, blue-eyed grass, collared lupine wishbone bush, Parry's phacelia, fern leaf phacelia and fiesta flower.

        Pinkish and red were represented by Calif. peony, scarlet pimpernel, redmaids, scarlet  pitcher sage, chaparral current, fuchsia flowered gooseberry, and prickly phlox. Also seen were sugar bush, wild sweet pea, Indian pink and wooly paint brush.

        Other sightings were foxtail barley, Madrid brome, wild oats, golden top, slender oats and red brome. Both scrub oak and coast live oak were in bloom. Several fungi were spotted including a large 5 inch diameter mushroom, a 3.5 inch diameter inverted top toadstool and numerous smaller toadstools.

        A rating of very good is awarded for the quantity and quality of blooms on this hike.  (RWM)

Rocky Oaks

Various trails

  Date: 4/9/06



        Our unseasonably cool weather has delayed the wildflower blooms here, but now things look promising. Most of the trails to the eastern edge of the site are still very wet and muddy and will keep you from exploring the meadow. In the areas surrounding the meadow you can see the beginnings of bloom: popcorn flowers, cryptantha, filaree and long-billed filaree, as well as lots of funnel-web spider webs and mushrooms. North of the pond area are small lupines. South of the pond the trail continues into drier chaparral vegetation and views start to improve. Firedot, candleflame and speckled greenshield lichens are clearly visible on black sage, chamise and other shrubs and you’ll find California buckwheat, lots of California everlasting and then patches of California poppies. As you continue west, blooms improve. The most impressive are the several types of ceanothus in bloom, especially the blue violet one, ceanothus oliganthus. You can also see Carolina geraniums, golden violets, more small blue lupines and some mountain mahogany, just starting to bloom before that trail ends at the far western edge of the park.  (SB)

Malibu Canyon State Park

Backbone Trail between Corral Trailhead and Tapia Park

  Date: 4/8/06



        This hike was section number six of the National Park Service's annual Backbone Trail hike. This section starts at the Corral Canyon trailhead and runs along the Mesa Peak Fire road then down to Tapia Park on Malibu Canyon Rd. A good portion of this hike is along the ridgeline offering some excellent vistas of both the ocean and the valley. Flower density is still low for this time of year which is somewhat offset by great displays of ceanothus, producing only a fair showing. All told about fifty species in bloom. Highlights include Greenbark ceanothus, prickly phlox, purple nightshade, Eastwood manzanita, manroot, sunflowers, Parry's phacelia, fiesta flower, virgins bower, a few different lupines, paintbrush, Indian pink, California blackberry, oxalis albicans, and, perhaps the most important, summer holly.  (RW)

Circle X Ranch

Grotto Trail

  Date: 4/7/06



        the flower situation looks similar to the last report for the Grotto Trail: except for a few species the quantity of individuals remain low. The species count is up but many in the count are represented by just one plant in bloom. The recent rains have left the trail muddy in places, although it should be fine by the time you read this. There is a lot of water in the creek, enough to make the creek crossings a bit of a challenge and the waterfalls worth looking at. In the evenings there is a lot of frog song mixed in with the sound of the rushing water. This trail is excellent for another of our blue ceanothus, the greenbark ceanothus. It is a much paler blue than the darker hairy-leaved ceanothus found up on the Sandstone Peak and Mishe Mokwa trails. Other flower highlights include good quantities of purple nightshade, a single white nightshade, several morning glories, everlasting, canyon sunflower, some chinese houses, blue larkspur, a few fiesta flowers, miner's lettuce, popcorn flower, a little blue eyed grass, some bush monkey flower, a few blue dicks, one star lily, a few scraggly wishbone bushes, a fuchsia flowered gooseberry, and wild cucumber.  (TV)

Point Mugu State Park

La Jolla Canyon Trail

  Date: 4/6/06



        On 4/06/06 we hiked up the La Jolla Canyon Trail and connected with the Loop Trail westerly. Our objective was to find the Creeping buttercups that had been washed out from last years rains. We found several plants, but none were blooming. Including the grasses and trees we found 48 species in bloom. The dominant color was yellow which included hedge mustard, giant coreopsis, bush sunflower, deerweed, telegraph weed and bush monkey flower. Also found were sour clover, golden yarrow, bur clover and tree tobacco. Slender bedstraw, canyon sunflower, western wallflower, snake root, Santa Barbara locoweed and prickly sow thistle concludes the yellowish group.

        Second most common were the whitish group which included morning glory, Calif. everlasting,  horehound, poison oak, and mule fat. Two-tone everlasting, Calif. buckwheat, cliff aster, bigpod ceanothus, wild blackberry, eucrypta, and popcorn flower rounds out this group.

        In the purple/blue category we found black sage, redstem filaree, purple night shade, rigid hedge nettle, greenbark ceanothus, blue dick, blue-eyed grass, and wishbone bush. Red/pink was represented by coast  paint brush, wild sweetpea, and scarlet pimpernel.

        Other sightings were rip-gut brome, red brome, Calif. walnut, slender oats, golden top, arroyo willow and wild oats.

        There was plenty of water flowing in the creeks and at least three waterfalls were on display. The trail was in good condition with only a couple of muddy sections. The ticks seem to be as plentiful as they were last year, so don't spare the deet.  (RWM)

Circle X Ranch

Sandstone Peak Trail

  Date: 3/31/06



        At the lower elevations near the trailhead things look similar to a few weeks ago: few flowers, both in term of species count and quantity of individuals. However, moving up to higher elevations we begin to encounter large numbers of very heavily laden hairy-leaved ceanothus and a good number of prickly phlox. The deep blue and hot pink of these two flowers provide the perfect counterpoint. There was one short section of the trail which also included an abundance of the white blossoms of the hoary-leaved ceanothus that struck me as being as beautiful as any wildflower display I have ever seen. It wasn't just the unusually heavy blossom load, but rather the whole aspect taken together. It felt almost as if a skilled artist had arranged the dramatic colors to produce a work of art. Last year was a banner year for flowers in general, but only average for the ceanothus. This year the ceanothus have been spectacular and worth a hike in their own right (perhaps some compensation for the otherwise poor flower showing we’ve had so far this year.)

        Other notable sightings included purple nightshade, several black sage bushes beginning to bloom, golden yarrow, and good numbers of another favorite, the Eastwood manzanita, near the top of the trail. Don't forget to look for the smaller flowers like the delicate California saxifrage along the talus slopes just below the highpoint of the ascending trail. A few weeks ago it looked like the wild cucumbers were beginning to dry up but they are in full bloom again, thanks perhaps to the recent rains. There are still some shooting stars about and even a few chaparral currents. So don't let the rather poor flower condition near the bottom of the trail stop you, its much better farther up out of sight.

        So how to rate this trail? It doesn’t seem quite fair to rate it too high based on the presence of just a few of really stand-out species, but then, flower watching has always been a rather subjective sport. If you love the “California Lilac” as much as I do, then perhaps even “Excellent” is justified. However, cooler heads would point out that on the basis of the variety of flowers in bloom this is still a rather poor showing. You’ll have to decide for yourself.  (TV)

Topanga State Park

Los Liones Trail

  Date: 3/30/06



        Trailhead at the end of Los Liones St. off Sunset Blvd., just in from PCH.

        This trail is just starting to come into bloom.  Elderberry flowers, deerweed and California everlasting are visible from the trailhead.  Hiking a little ways brings you to canyon sunflower, morning glory, purple and white nightshade, wild cucumber, sticky monkey flower, bush sunflower and cliff aster.  This is a trail that is known for phacelia.  Not much yet but we did see some parry's and big flower phacelia..  (DS)

Malibu Creek State Park

Reagan Meadows

  Date: 3/23/06



        This is a lovely hike and one where you are not likely to encounter many other people.  Park in the gravel lot at the southeast corner of Mulholland and Cornell and walk up the paved driveway to the   park buildings.  Beyond the buildings the trail is obvious.  Soon the trail forks and you can choose the left and the meadow first or right and the woods, you can loop back the other way.  Either choice is perfumed with the scent of ceanothus.  I took the meadow trail first.  There are brambles of golden current and little yellow violets peeping out at the edge of the trail.  There is common fiddleneck, miner's lettuce, chaparral current, and, of course the ceanothus.  Curving uphill to the right at the end of the meadow you can return through the woods.  Here you find western wallflower, baby blue eyes, fiesta flower, larkspur and Chinese houses.  (DS)

Topanga State Park

Dead Horse & Musch trails

  Date: 3/22/06



        Dead Horse Trail to Musch trail and return to Dead Horse on the fire road.

        The recent rains are paying off in flowers.  Things are really starting to bloom.  The Dead Horse Trail is riparian at the beginning and then goes to chaparral.  In the riparian area there is blooming chamise, greenbark ceanothus, canyon sunflower, hummingbird sage and manzanita.  Above the footbridge there are several dozen peonies in bloom, they must have waited for the rain.  In the chaparral area there are fuchsia flowering gooseberry and vervain.  In the meadow before the trail meets the Musch Trail there are buttercups and blue eyed grass.  Going up the Musch Trail there is sticky monkey flower, purple nightshade, California buckwheat, California everlasting, wild morning glory and golden yarrow.  The most notable plant in bloom is notable penstemon which is just gorgeous and there is quite a bit of it.  There are also some lovely tree poppies.  Coming down the fire road to the Trippet Ranch parking lot there are still some prickly phlox hanging on.  (DS)

Cold Creek Preserve

Stunt High Trail

  Date: 3/16/06



        This canyon is a wonderful hike in any season but especially nice in the spring.  The creek is full of water and the deep shade of the canyon bottom is refreshing.  Right at the trail head is some mustard evening primrose.  There are a lot of deep blue ceanothus throughout the canyon.  By the creek there are purple nightshade, California everlasting, wild cucumbers, miner's lettuce, milkmaids and fuchsia flowering gooseberry.  There are bunches of baby blue eyes in every sunlit patch. 

        Going up the hill into the meadow there are golden yarrow, lupine, popcorn flower, common fiddleneck, sweet peas, fiesta flowers, blue dicks and blue eyed grass. 

        Continuing into the chaparral there is Eastwood manzanita and the beautiful flowering ash trees dripping with creamy yellow blossoms.  (DS)
