Thank you Dee. I just read that this plant produces flowers. I didn't know it flowered! I can't wait. :)

Hi, Looks like "fire witch" dianthus to me. Bluestone perennials has it. It's a pretty common dianthus - and very beautiful - so I would replace it too!

in my experience.. they are not a long lived plant ... and i would be happy with getting 4 years out of it ... of course.. others will chime in.. that great grand ma brought it over on the mayflower.. and it has been in the family garden for a century.. lol ... and i would suggest.. you not get wrapped up on getting an exact duplicate ... in the flower world ... the newest and brightest stuff commands the highest price.. and older stuff just goes by the wayside ... even if they look exactly the same.. lol ... one way to avoid a situation like this ... is to divide your plants .. to keep them more vigorous... but also to have duplicates in other parts of your garden... and if one dies.. you have other to continue the tradition ... if you are going to hang around with us.. add your location on your members page.. so it shows up in all your posts ...if we knew such.. we might have a better idea of how long it should live ... ken

Yes I believe only polyembryonic mango seeds produce fruit true to its parent. Here's an article below that helps explain it the difference between monoembryonic and polyembryonic seeds. https://homeguides.sfgate.com/growth-mango-seeds-41463.html I have a Keitt mango tree and the fruits are a late variety usually August thru as late as Oct. here in central Fl. The fruits are quite large (up to 3 lbs) sometimes, also and they aren't round. the kents are smaller but they also are not round. There is a pretty good website that shows some of the common varieties grown in FL but there are SO many new ones come out all the time. But if it was grown from seed that is http://www.tropicalfruitnursery.com/variety-viewer-variety-mango-reference-4 If that was grown from seed there is a very good chance you may never know the variety? Is it stringy or has very little to now fibers? Usually if you have to floss after eating a mango it's probably seed grown, though Tommy Atkins is one that comes to mind that's known to be somewhat stringy. It is one of the most produced variety for shipping for super markets due to its very colorful skin when ripe and also ships very well...but taste is not the best for growing in your backyard.
