It is a large showy species with dark red-maroon to purple flowers with broad petals that are slightly flatter than those of T simile. Of course occasional white, pink cream and yellow forms can be found together with beautiful bicolors and picotees. (Picotee is a variety of flower whose edge is a different color than flower's base.) (The word originates from the French picote, meaning 'marked with points'.)
