I believe it should be sown in fall like seed of most
winter-to-spring growing bulbs. The seeds, however, probably can
remain viable for long periods in dry storage, since they come from a
semi-arid region with unpredictable moisture from year to year.

I always start watering my tecophilaeas in the bulb frame in fall.
They do not emerge until spring, later than many bulbs. Presumably
they start some root growth earlier than the leaves and flowers come.
Tecophilaea cyanocrocus here flowers with Fritillaria pudica and
Lewisia brachycalyx, a very attractive combination.

I would not try this product in a seed mix, especially since there
are tried and true organic materials that work well, are cheap and
readily available. As I observed a while back, I note that coffee
grounds appear to inhibit germination of annual weeds when applied to
a surface.
