Hi Judy, At first glance, your neighbor's resembles my Gladiolus italicus but mine bloomed in April. Look and see if yours matches these photos: http://flickr.com/photos/gastils_garden/… or these: http://pacificbulbsociety.org/pbswiki/index.php/… There are several Gladiolus species that look similar. Im waiting until I see the mature seeds to confirm my id before posting my photos to the wiki since G. italicus have distinct seeds. It is a winter grower so compared to the summer-growing Gladiolus it could be called early. - Gastil
