An improved heat protective plant wrap for surrounding a plant comprises: a paperboard sleeve having an open top end portion and an open bottom end portion wherein the top end portion has interior faces therearound colored to absorb light. Sunlight is absorbed by the colored interior face in the top end portion rather than being reflected therein. A top portion of the plant therein, adjacent to the colored interior face, remains substantially closer to ambient temperature in the sunlight. In a preferred aspect of this invention the paperboard sleeve comprises a generally square tubular member having parallel pre-folded elongate arrises to facilitate storage, shipping, handling, and erection.
