Turns out that some of the seeds I ‘cast’ into pots this past spring season have germinated over the recent holiday weekend, including some Claytonia saxosa seeds collected from the North Coast Ranges of California. The cotyledons on these plants (pictured above) are a bit unlike the rest of the lot that have germinated in that they are very short and stout, in addition to being deep green in pigmentation. Thus far, all of the other “up and coming” seedlings, including those of C. rubra collected from the San Bernardino Mountains (pictured below), appear to have very elongate cotyledons that are considerably more strap-shaped and light green in pigmentation in comparison to C. saxosa.
In addition, there appears to be some differences among the taxa with more elongate cotyledons, as demonstrated by the C. gypsophiloides seedlings pictured below which seem to stand a bit taller than the rest of the species that have germinated thus far!Compare the cotyledons of C. gypsophiloides (above) with those of some C. perfoliata X parviflora hybrids from northern California (below) and you might wonder if you couldn’t identify Claytonia before their first true leaves emerge!
I’ll be interested to see how things develop as we move closer to flowering season for Claytonia! The peculiarities of the C. saxosa seedlings are quite intriguing — I can’t wait for my tuberous perennials to germinate!!!
