Seeds are easy to germinate but higher % is achieved with 3 or 4 weeks of stratification. It's one of the more easy conifers to grow from seeds and isn't prone to fungi or other seedling diseases. Growth rate is pretty fast for a conifer and foliage is very aromatic.
I recommend planting large specimen outside because smaller ones fail in temperate zone maybe it succeeds if you provide a microclimate. Smaller specimen would tolerate around -8C or -10C but i can imagine mature specimen would easily resist -18C. Rootbound severly slows growth so be aware. Lately i was thinking germinating them from seed again they are fun, most cold hardy conifers need 3 months of stratification below zero.
Personally i think goldcrest is a better choice for average or small gardens, macrocarpa can get pretty huge.

Impressive and beautiful tree- takes salt air well and very drought tolerant (though does well with watering, too).
