The "Acanthocalycium violaceum" name has been placed as a synonym as a result of the recent re-classifications. The new designation for this plant is "Acanthocalycium spiniflorum var. violaceum"
The flowers are pink for Acanthocalycium spiniflorum var. violaceum and are about 1.6 inches wide.
This plant can reach 2 ft high and 6 inches wide. Although mine has already reached 7 inches wide.

I have not grown this plant. Acanthocalycium violaceum is native to Argentina. It has many ribs and dense honey-colored spinesis and has a globular shape. It can grow to 5" inches diameter. Lilac blooms to 3" inches in diameter appear during late spring and summer. Although it is cold tolerant, one should give it frost protection to prevent scarring.
