Descripción

This is the same colony that I made an iNaturalist observation with in 2022 (more of its story in the linked observation) It is "wild" by iNaturalist's definition of self-seeded being "wild", but I started the colony with a few plants plants about 5 years ago, and by my definition, each generation, that a species is self seeded after it was planted in a location, the population there is a little more "wild" and "natural". So this colony is now about 5 generations more "wild" and "natural" than the few plants I started it with about 5 years ago.

This season I had a small handful of seedlings that germinated not long after the Fall rains came, and they all died with the 2 days of 15 degree weather. After the big crop I had the previous year, I was very disappointed! Then, maybe a week ago or so, I saw thousands of tiny cotyledons germinating where that colony was! I was optimistic they were a later germination of Collomia heterophylla! Then yesterday I noticed, on a seedling or two that I examined, the wrinkled surface that I've come to recognize as that of Collomia heterophylla cotyledons! (much like the cotyledons of Collomia grandiflora, but their true leaves are radically different.)

I now hope that a few other spots in the park, where I had Fall sprouted Collomia heterophyllas die, will show similar recoveries.

It seems like this species hedges its bets with early and later germination times for their seeds. Those that germinate with the Fall rains might be bigger than those that germinate later, but having others germinate after the peak cold of the winter allow the population to continue even if all of the Fall germinating plants die in the colder weather!
