Staghorn ferns are epiphytes. They cling to tree trunks, rocks or whatever they happen to grab onto. They can root into decayed wood if it is porous enough, but they are satisfied to just cling to the exterior. They do not need soil. They sort of make their own soil by collecting debris that falls from the canopies of trees above. In the jungles where they live, they get all the water they need from rain. They often live in the crotches of branches because that is where they happen to land. (The epiphyte I wrote about earlier was just a palm that landed in the wrong place, but is not really an epiphyte. https://tonytomeo.wordpress.com/2017/11/15/epiphyte/ )
In home gardens, staghorn ferns are often grown on wooden plaques so that they can be moved around like potted plants. Because it does not rain much here, they need to be watered occasionally. They do not grow very fast, but eventually need to be attached to larger plaques, or divided into smaller clumps that fit onto new plaques. Alternatively, they can be grown like plants in hanging pots, but without the pots. Even if they start out in pots, they may eventually envelop and obscure their pots, and form a big rounded hanging mass that only wants water and debris from above. A small bit of fertilizer might improve their naturally light color, but too much will roast leaf margins.
My colleague Brent Green acquired this humongous and well rounded specimen from a client who wanted it removed from an olive tree that it had grown too big for. It had been there for decades. Brent gives it a banana every month or so because it likes potassium. It does not get much debris from above in Brent’s well groomed garden.
What an unappealing name! That is probably why so many of us know it simply as ‘wild onion’ or ‘allium’. Few of us bother to get sufficiently acquainted with it to know it by the species name of Allium triquetrum, which is actually not much more appealing than ‘onion weed’. It is not really wild, but has naturalized as an invasive exotic, or in other words, ‘weed’. At least it is a pretty weed.
It is not easy to forget annual forget-me-not, Myosotis sylvatica. Even if it dies back early in the heat of summer, it will probably throw plenty of seed to regenerate through next winter, and bloom again by next spring. It can easily naturalize in damp or riparian areas, and might be considered to be a weed; but like nasturtium and foxglove, it is a polite weed that is not aggressively invasive.
Just before the weather gets warm enough for real marigolds, and after the weather starts to get too cool and rainy for them, pot marigold, Calendula officinalis, is at its best. It can bloom at any time of year, depending on when it gets planted, but prefers cool and humid spring and autumn weather. It is not so keen on frost in winter, or the arid warmth of summer that real marigolds enjoy.
It is a shame that forsythia is not more popular here. Years ago, there was a commonly perpetuated myth that winters were not cool enough for it, as well as lilac. We now know that both lilac and forsythia are happy to bloom here. Now, some might insist that there are so many evergreen shrubs that bloom nicely right through winter, that there is no need for deciduous blooming shrubbery.
This is one of those plants that many of us have strong feelings about. Many of us who remember it from when it was more popular in the 1970s might consider Algerian ivy, Hedera canariensis, to be an aggressively invasive weed. Those of us who are less familiar with it might appreciate it as a vigorous and resilient groundcover that gets dense enough to exclude most other weeds.
We tend to think of currants as being from Europe, Russia or Eastern North America. The pink flowering currant, Ribes sanguineum glutinosum, is actually endemic to canyons and riparian sites of the coastal ranges of California. Because it is an understory species that lives in the partial shade of large trees, it is quite tolerant of shade, and even prefers a bit of shade rather than full sun.
What ever happened to Point Reyes ceanothus? It is such a nice low growing shrub, with small holly-like leaves, and cheery blue flowers in very early spring. It was quite popular when it initially became available, but now seems to be rare. Maritime ceanothus, Ceanothus maritimus, from San Luis Obispo County, is a similar species that presently seems to be getting more attention.
You might think that such a popular flower would be easy to get a picture of. Baby’s breath, Gypsophila paniculata, is everywhere, and almost a standard component of the mixed bouquets found in supermarkets. However, the flowers are so small and so sparsely arranged on thin stems, that they do not look like much in pictures. This picture is a closeup of a tightly bound bundle of bloom.
This one is different though. It is not the characteristic homogeneous bright orange that California poppies should be. The orange in the middle is what the entire flower should look like. The outer yellow hallow is not typical.
