South Washington Cascades:
Recommended for South East England and East Scot-
land in which SWCA sources expect to have superior
growth rates. Care must be taken to avoid spring frosts.
Washington Coast:
The Primary choice for the general range of sites types
suitable for Douglas Fir in the UK would be WACO.
Superior for survival and frost hardiness.
NWCA
North Washington Cascades:
Suitable alternative to WACO and SWCA. Most Douglas
Fir planted in the UK has been from NWCA seed.
North Oregon Coast:
Too frost sensitive for most UK Planting

Choice of Douglas Fir seed is crucial for good establishment and maximum yield from the crop. At Alba, we follow the FC guidance given in Bulletin 129 and this factsheet provides a summary of their recommendations.
Alba grows quality Douglas Fir from a range of these seed sources to suit sites throughout the UK.

We also use Improved Seed from the leading French Seed House
Vilmorin. Clones used to set up the French Breeding programme
were taken from the same areas in the Pacific North West as are
recommended for planting in the UK. We have separate factsheets
for each orchard, shown below, giving more information.
