Wintersweet is a fast growing, large, rangy shrub. Give it plenty of room! The scent is powerful, however, winter weather can interfere with the show, cold wet weather can quickly ruin the small flowers. Easy to grow from seed, that is how I got mine. Fall leaf color is yellow.
I grew the straight species from seed and had the shrub some years until it outgrew its space. Meanwhile I grew a double-flowered improved one from seed also, and still have that one. It is blooming late January into February (2021). Flowers are the same size as species, certainly not the 1-2 inches listed on the 'Luteus'. But the flowers on this are double, seem a little sturdier, and seem to have more buds than the species. Still, bud count could be location difference (more sun.)
2024 update- still doing well, more flowers each year, and this year they are lasting quite a while (weeks).
