I'm not sure if it's difficult or just time consuming...Boxwood grows quite slowly; most gardeners prefer the faster reward of cuttings.

Buxus microphylla , sow @ 70ºF, if no germ. in 4 wks, move to 39ºF for 4 to 12 wks, recycle (multiple cycles may be required)
Buxus sempervirens , sow @ 70ºF, if no germ. in 4 wks, move to 39ºF for 4 to 12 wks, recycle (multiple cycles may be required)

But I've never found ripe seed on my own (and I've looked).
My 16 plants in three very dwarf varieties don't lend themselves to cutting for wreaths either, wish they did...

Thank you for your advice MorZ8, I will try my best with these seeds. I hope they are ripen - found in brown capsule which was dry - I will sow them probably into the pot when the daylight will increase....
