Shooting Star Seed Capsules

Seed capsules of shooting star (Dodecatheon clevelandii ssp. patulum)

As we’ve seen this Winter, it is the norm for Southern California’s weather to be abnormal. Cool, wet weather in December was followed by weeks of warm, dry weather in January. It is hard to predict when it will be wet and when it will be dry. Especially if you are a plant.

This photograph of a shooting star (Dodecatheon clevelandii ssp. patulum) is from early February, when the weather was dry. Droplets of moisture can be seen clinging to the interior walls of the seed capsules. These climate moderated capsules helps ensure that the plant will produce viable seeds, even if an extended period of dry weather should occur after the plant blooms.

Winter Bloom

Deep in shade on a north-facing chaparral slope, this California fuchsia (Epilobium canum ssp. canum) has not savored direct sunshine for weeks. Overnight temperatures in the Santa Monica Mountains have dropped to freezing several times this Winter, and frosts have been common. But this hardy plant continues to bloom.

According to the Jepson Manual this subspecies ranges up to about 5000 ft. in elevation, and the parent species up to about 10,000 ft. As a genus, Epilobium is well represented by species that grow at higher latitudes and elevations, and must have developed adaptations that help it flourish in cooler climes.

Hexagonal Close Packing

Hexagonal close packing of the disk florets of an immature Sneezeweed blossom.

There are some imperfections, but generally the unopened disk florets comprising the head of this immature sneezeweed blossom are arranged so that each floret is surrounded by six other florets. This is an example of hexagonal close packing, and is probably the most dense arrangement of florets that can be achieved in this spherical flower head.

The photograph of the Bigelow’s sneezeweed (Helenium bigelovii) was taken on an out and back run on the Pacific Crest Trail from Vincent Gap to Little Jimmy Spring during July 2007.
