My various attempts to germinate the white sage seeds spanned more than a year, from some time in 2009 until now.

To date, I have tried a few methods, all of which did not produce any results until my latest attempt:
1. I have tried my traditional method of heating/warming the seeds up in a metal container filled with vermiculite, and placed on top of an aromatherapy burner, but the seeds didn’t germinate;

The pink paper is the seed primer, filled with the chemicals found after wildfires, which helps with wild plants' germination

2. I have sowed the seeds into transparent containers filled with pure vermiculite and maintained the humidity of the container at a level suitable for most other germination of seeds; this method sometimes made the white sage seeds sprout, but they always rotted within a day or two after that if not quickly transplanted; and even if they were transplanted at this stage, sometimes the seeds dried up in their new environment anyway;

3. I have bought seed primers and soaked the seeds in the chemically-infused water, to no avail;

4. This is the method which has finally worked, and I came upon it through laziness and a mistake: I soaked the seeds in water which came up to about twice their height, and I left the seeds for 36 hours. For the first time, because of my laziness (I’d originally intended to soak them only for 24 hours), the water level evaporated until the seeds were only moistened, but out of the six I’d soaked, two had sprouted. I sowed all of them, and another seed sprouted a few days later.

The rightmost seedling is the one which looks like it has a rotting stem

A few days ago, I tried this method again. I soaked all the seeds for two days, and then sowed them into a well-draining soil mix, and then covered the mouth of the pot up with clear plastic bag. For now, one out of six seeds have sprouted.

Since the white sage is a desert plant, I mix soil with a lot of volcanic sand, and water the seedlings sparingly every day. I’m still experimenting with the amount of water to give, since there is one seedling which, though growing, seems like it has a rotting stem close to the soil’s surface, while the other two are more or less fine.

Once the plants grow to larger sizes, I intend to treat them like I’m treating my sole white sage plant now, by giving them the full morning sun, and watering only twice a week.
