I planted mine about 1.5" for a 1-cm corm and it was very happy. It sent up one leaf and six smaller ones, and an inflorescence that smelled like bathroom cleaner.

Another tip: direct sun on a hot day caused a few of the smaller leaves to flop over and die. In the shade, it tolerated temperatures into the low 90s.
