I have grown this plant from a packet of mixed seed bought in Tenerife. Sown in 2002 it has grown quite happily in a 12" pot (I didn't want it to get too big). I have always thought it was a yucca. It decided to flower this spring but the inflorescence looks like no yucca or related plant I can find on Google. Can anyone help?
Thank you
