Purple Gladiola

Last year i bought 10 gladdy bulbs 5 came out white the others didnt flower i left them in but when the fence blew down they had to come up when we built a new one and i forgot to put them back in. When i remembered it was late and although they grew leaves i didnt expect flowers but 4 have flowered 2 white and 2 this lovely purple. I am really pleased.
