Not sure about this variety, but many types set blackish berries. Lantanas are somewhat easy to propagate from cuttings. Remember, you can mail cuttings - just cut off the branches so they are pencil shaped and then wrap a few in a ziplocked bag. A guy in CA sent me a bunch of fig cuttings in a freezer-sized ziplocked bag with a damp paper towel in it. They are rooted ! He sent it third class mail, so it didn't cost much. If you are sending or recieving a few different plants this way, it is cost effective. Just one... well, it depends on the cost of the original variety, I guess. Remember, most cuttings are just routine prunings that you'd toss out anyway. So, if they get lost in third class, el cheapo mail, so what ?!
