What have you observed re: blooming cycle of hippie imports from S Africa or Australia?

I bought some Sonatinis this fall and they're about to bloom. When will they bloom again? Next spring or ...

Years ago I got some Australian hippies which were planted in summer. They did not bloom for me until the 2nd spring following planting time and then every spring thereafter. .

Just wondering if bulbs originally grown in Southern Hemisphere (and subsequently imported to northern hemisphere.) readjust their growth/blooming cycle.

And to further complicate my question, how do growers get Dutch hippies to bloom in Dec, when they're typically spring/summer bloomers in the US?

In my experience, Southern Hemisphere bulbs reset their biological clocks to the northern hemisphere. So you may have a lag until they bloom again in our second spring. The Dutch Amaryllis are dug up in the summer (theirs and ours), put into cold rooms to force hibernation, then shipped in Oct-Dec so they think it is spring when they arrive at our homes, blooming Dec-Feb the first year. Southern Hemisphere bulbs are dug in their summer, put into cold storage in their fall (our spring) and shipped in Sept, Oct. They usually bloom the first year in Dec.

Thank you so much and Merry Christmas. I was kinda thinking that's what would happen. Sort of plant jet lag, ha.

I even seen a problem for bulbs in the same Hemisphere. When ordering from England, were bulbs blooming in summer and sleeping in winter, has a problem with a local weather, were bulbs are green all year around, and blooming after the winter or in winter itself.

We have a very difficult weather to grow most of the plants, it can be up to 100 F (or sometimes even higher)in summer, with humidity ranging from 20 to 90% , and up to almost 40 F in winter, but again it can be even 80 F with low humidity in winter (like we have this week).
This summer was extremely hot and dry, with temperatures above 95-100F for a weeks in a raw, my amaryllises were loosing the leaves because of it in the summer (never happened before), and was almost no bulb increase in summer because of that.

P.S. sorry for my problematic English,
