what does the sprig of acacia symbolise in craft masonry and where does that reading come from

The sprig of acacia carries three principal symbolic meanings: immortality of the soul, moral innocence, and initiation 2.

Its pre-eminent reading is as an emblem of immortality and spiritual survival 12. Because the acacia is an evergreen whose foliage remains green when other foliage dies, it represents the persistent renewal of life and the immortal part of man that survives the grave 12. It is also treated as an emblem of faith in that future life and in divine order 1.

The reading of the acacia as a symbol of innocence relies on a linguistic double meaning: the Greek word *akakia* denotes both the botanical plant and the moral quality of innocence or freedom from sin 232. William Hutchinson emphasized this interpretation in 1775, arguing that the symbol denotes the purity of life expected of a Mason 2.

As a symbol of initiation, the acacia serves as the Masonic equivalent of sacred plants used in the ancient mysteries—such as the lotus in Egypt and India, the erica in the myth of Osiris, the mistletoe of the Druids, and the myrtle of Greece 12. In those ancient rites, a sacred plant marked the candidate's symbolic journey through death to a resurrected or enlightened state, a function the acacia retains in the Third Degree narrative where it marks the temporary resting place of the Master Builder 132.

The reverent use of the plant also draws on biblical tradition, where shittim (acacia) was regarded as a sacred wood used in constructing the Tabernacle and the Ark of the Covenant 12.
