The Jepson eFlora indicates that it grows in adobe, appropriate since its common name is Striped Adobe Lily. I visited a population a few miles north of the Tejon Ranch on March 17 and they were in full bloom. They were growing, there, with a nice Lomatium of some sort, a number of very low wild flowers, and Chlorogalum pomeridianum. The grasses weren't particularly high.
That part of California can have long extended periods in the Summer of temps in the low hundreds. Its a table grape growing area, particularly for selections that benefit from such high heat.

This is a great discussion. The advice of experts like Jane is always the
most useful thing, but in cases where that's not available, here's an easy
way to learn more about the growing conditions for most summer-dry bulb
species:
First, look on iNaturalist. In the case of F. striata, you will find a bunch
of photos of it in bloom, and even one photo of a seed pod. Not all of the
photos are closeups, so if you browse around, you can see how high the grass
is around the plants. By bloom time the low-growing leaves of the plant are
in filtered shade, but the flowering head pokes up into bright sunlight.
Check it out:

My guess is, knowing how annual grass grows in California, the leaves would
be much more exposed to sun in winter. The annual grass doesn't really
elongate until the weather starts to warm in spring.
Jane told us that these seeds came from Tejon Ranch, which corresponds to
the southern cluster of observations in the map on iNaturalist. The flower
photos there are all dated Feb-March, and the photo of a large seed pod, not
yet dried, is dated April. So you know when they bloom (mid-Spring), and can
make a guess on when those seeds ripen (end of spring).
Using the map on iNaturalist, you can also make a guess at the climate these
plants grow in. Note the location of the flowers, and then look it up in
the Mediterranean-climate maps we host on the wiki, which you can find here:
https://pacificbulbsociety.org/pbswiki/index.php/…
Looking at the climate map for California, it looks like spot where the
Tejon Ranch population grows is probably zone D2, which corresponds to the
eastern Sierra foothills, Red Bluff California, Ceres South Africa, and
small mountain areas in places like Spain and North Africa. In other words,
a bit wetter in winter than a true desert, but quite dry in summer and
frosty in winter (overnight low temps average close to freezing in winter).
These plants should withstand a light frost easily, and may even expect some
chilling in winter. However, they're going to want a fair amount of sunlight
during the day, and will not appreciate being buried under snow for weeks or
months.
What the info above doesn't tell you is anything about soil, which makes a
huge difference. But you can at least make a guess about watering schedule
and cold tolerance.
All of the above just repeats what Jane already told us, but my point is
that you can find a lot of info on your own with a couple of web lookups.
You can do this sort of lookup for any species listed on iNaturalist, which
is a lot of them.
Hope that helps,
