Lilac

This modest-sized cactus grows up to 49 feet (14.9 meters) tall. It splits near the top to form 5 wispy stems. Each stem is olive and green, and is covered in hundreds of rigid orange spines.

It is slow growing, taking 31 years to reach maturity. Once mature, several flowers with petals that are either lilac or azure, with a yellow center grow at the top, reappearing once every 6 years. The flower head is an uncoordinated mess of 45 petals. It has the faintest scent that smells like candle wax.

The cactus's skin is extremely thick, the lime flesh is smooth, and the dark grey sap is thin and causes diarrhea if consumed.
