You bought two, John, lucky you. Your garden will be nicely scented. They just like a light, well drained neutral soil in sun or part shade. They will grow to about 1.5m in bpoth height and diameter, so could go into containers, at least to start with.

One thing to bear in mind is that they hate being disturbed - so transplanting is not advised. Daphnes are a bit temperamental. I hope yours settle down well - enjoy them! :-)

If you do decide to plant them in containers, make sure they never dry out and never get waterlogged. They are easier to manage planted in the garden

I did give an answer, but it slipped "away", anyway, first I want to say congrats as U R going to adore them. I planted mine in very protected spots, also well drained as mentioned.( I have 3 of these beauties,) one is not in protected area, and it is not as robust & I transplanted it, so it is pouting even after 3 yrs.
Spritz is on the dot when she tells U, "do not disturbed them once planted & if in a container make it huge.
Mine is late this year because of lousy weather, but I planted mine in spots where we enter our home as to enjoy the aromas. Prune & shape after blooming) Do not neglect this) or else U will get a plant that collapse under it's weight. So prune it to the shape U want it. Goodluck.

I haven't had any problems growing Daphne odora in containers but you may want to pinch them back to keep them from getting leggy. If it's a variegated variety then you may want to give it shade during the hottest parts of the day too. Good drainage is critical and this D. odora is less tolerant of alkaline soil than other varieties (watch for iron deficiency). If it's a plastic container then it may get hot and dry out faster too. If you're planning to keep it a while clay, stone or hypertufa make good containers. They're pretty easy to root from cuttings so if nothing else you can keep growing new ones if the original doesn't make it.
Best wishes, they can be finicky but well worth the effort!
