Has put on a few new blooms here...approx 3 months after the initial spring flush. Maybe it's not strictly once blooming?
-edit- 15 April 2018 Almost a year since getting it and while it's grown to about 60cm wide on a few canes, it's still essentially the same height it arrived at, approx 40cm. I'm just not convinced this is going to reach 180cm+....although noting in pictures that Simon Voorwinde makes mention it took 5 years for him before it started growing strongly.
-edit- July 28 2018 It's making flower buds again, just on one branch, there's no leaves on the plant...it's the middle of winter here in Australia. There has been a few slight frost/freeze nights (ie wake in the morning and the temp is about 2c and the lawns have a coating of ice on them that's melted by 10am) in the past couple of weeks. Either way, not the strictest once bloomer here.
it flowers before it puts on significant new growth, I assume this means it blooms on old wood....not something I'm super familiar with.
-edit December 3 2019-
Finally got seeds from it, first year it's formed hips here, seed count between 1 and 5 per hip. Close to 100 total harvest with various reblooming dips (polys, chinas, teas, rugosas) hopefully germination occurs and deep yellow isn't incredibly rare among the results
Apparently the name 'Golden Chersonese' is derived from 'Chersonesus Aurea', an ancient Greek (150AD) name for the Malay Peninsula where plentiful gold was to be found.
Given the possible difference between Australia and others, can you shed any light on the following:
How big are the flowers? Is it strongly fragrant like listed?
I got the plant this year (bare root) around the end of july, it may have been the unusually warm temps but it went in to bloom a few weeks ago, the plant is basically the same size it was when it arrived, it just has a bunch of leaves now...so that may be affecting things quite a lot compared to a plant that's had more time to settle in but given the once flowering habit may have to wait a year to confirm for myself.
