I no longer live in an area where Amaryllis belladonna grows easily. I have it in my garden in Phoenix, Arizona, where it just survives. I need to water it several times each summer, or it dies. I have tried watering it weekly through the summer to see whether this would lead to flowers. I get flowers very rarely. I don't have any idea why it sometimes chooses to flower. I have read flowers are actually produced years in advance of their emergence, and thus reflect care in years past. I don't know whether this is true.

When in my teens I lived in Orange County, California, a Mediterranean climate, with absolutely no warm-season rain during the years I passed there. Though I was young, I looked carefully. I never saw any seedlings sprout under any plants of this species.

Later I experienced the climate in San Francisco for four years.

I believe the cool-season rains in California are neither regular enough, nor plentiful enough, for Amaryllis belladonna to grow from seed without intentional watering by a gardener. I cannot imagine it would become established on its own more than extremely rarely, let alone invasive.
