It only grows in pine rocklands, marl prairies, and the transitional edges of these habitats.

Pineland spurge, with its woody taproot is likely a long-live perennial, though data on observed lifespans is lacking.

It reproduces sexually and has green blooms. Fruit production is year-round, with a peak in the fall. Little is known about wedge spurge’s reproduction; however, other congeneric species are completely reliant on insects for pollination and seed production while others are self-pollinating. Pollinators may include bees, flies, ants, and wasps. Ants have been observed visiting flowers of conspecific taxa, though it remains unclear whether they are effective pollinators.

The pineland sandmat grows erect with red stems and triangular-to-oval-shaped silver-green leaves that have a dense covering of long hairs. The fruit is a soft, fuzzy capsule a little more than 1/16^th inch wide with small yellow wrinkled seeds.

The deltoid spurge complex is distinguished from other similar Euphorbia species that may be found in pine rocklands by the small, triangular leaves. Pineland spurge can be separated from other deltoid spurges by its dense, long hairs and erect habit.
