Hi, It is an Echium, but I don't believe it is vulgare. I've grown E. vulgare and it has more a looser flower arrangement. http://i65.photobucket.com/albums/h234/Remyo_2006/garden%202007/Echiumperennial.jpg Your is much tighter. It looks more like Echium candicans or a similar one that I do not know. Remy Here is a link that might be useful: Echium candicans

The first one is Ground Ivy, also known by several other names including Creeping Charlie. A non-native weed that is probably all through your lawn, too. The next one appears to be a cherry, perhaps Black Cherry Prunus serotina. The throny shrub is a rose, and probably multiflora rose, which is very common, non-native, and something you should be pulling or else it will quickly become out of control. I think the last picture might be Common Fleabane, or perhaps Daisy Fleabane. Both are quite common here, and I think it is the Common Fleabane that pops up all over the place every spring.

I've sent the picture to a bunch of plant experts. Do you have the nursery name where you purchased it? Perhaps the owner would know more than the clerk. Where in Florida, if I may ask. The people to whom I've sent the photos are well known experts and curators at arboreta. Some work in Florida.

It's definitely a very, very fast spreader. My daughter in law inherited this plant when she bought her house two years ago and this thing is planted all over her yard. We had no idea what it was. I was planning on using it as a ground cover under the trees in my property in the woods. I admit I was determined to plant it last night but decided to check just in case. Boy, I'm so glad I did! And I truly appreciate your very timely response. This beauty is going in the trash as soon as I'm done typing! Thank you!!!
