At small sizes a black planter is an accent. At large sizes it becomes part of the structure of a space, which is why matte black is specified so often on commercial entrances, hotel terraces and rooftop schemes. A large dark volume grounds a facade in a way a pale one does not, and it holds its outline at a distance where detail stops reading.
The practical argument for fiberglass is strongest here. Jay Scotts put it plainly in their own comparison of materials: fiberglass planters are much easier than concrete to move around. That matters twice over on a large planter, once when it arrives and once whenever the scheme changes. It also matters structurally, because a rooftop or a balcony has a load limit and a large concrete trough can exhaust it before the soil is in.
A planter is listed here when it is offered in a large size and in Matte Black. Sizes within a family vary, so read the size table on each product page: the largest sizes ship by freight truck and are delivered curbside, while smaller sizes in the same family often ship free by ground.
