One of the things that makes me most sad when beginning to work with brides is when they bring in pictures - usually sourced online - that feature roses that we just can't get in New Zealand.
(Although this is changing with the arrival of the fab David Austin Roses) -->
We have a smaller population, less flower growers, and this does have an imact on the availability of some flowers including roses.
Did you know in America - most roses are imported directly from Columbia? Different growing conditions, bigger growers, more sales = more varieties.
Even the fact we do not allow Genetic modification has an impact on what varieties of flowers we can get here!
