Frost hardy citrus in Poland, zone 6

Marcin:
This year I'm observing pure Poncirus producing flowers on new growth. On Flying dragon I found two twigs with terminal flower buds, and additionally having small flower buds in leaf axils. Another poncirus made one terminal flower. It's suprising for me, I always thought such mode of flowering was the domain of hybrids. Have you observed such flowers on Poncirus?



Yolar hybrid is regrowing, and its twisted sibling (Orla) survived even better. Maybe it's more hardy, or perhaps Yolar was damaged more because I cut it during winter. It should become known after the next winter.



A positive suprise - limequat × procimequat hybrid seedling (Prores4) survived in ground in the greenhouse. It wasn't protected in any other way, I didn't make a mound, it just stayed there as it was.

In my climate pure PT is very often flowers a second time in summer on the new growth.
Do Yolar and Orla come from FD fruits?

In my climate it also happens, blooming in July or August in leaf axils of already hardened twigs. But I've never noticed, or never payed attention to flowers occuring directly on new growth of Poncirus.

Yes, both come from Flying dragon seed.

Marcin:
This year, many of the twigs on Flying dragon are essentially thornless or have rather short thorns. It seems its thorniness decreases with age/node count.


Another poncirus (not fruiting yet) has produced some monstruous thorns:

Hello, Marcin!
A flying Dragon must have thorns. They decorate it.  :D

Interesting information. I didn't know that a Flying Dragon could lose its thorns.
