Yes, fruitnut, that was the nectarine cultivar you recommended, and it has proven to be one of the biggest winners in my orchard. Extremely prolific, sweet, but nicely complex, not just "sugary". Same with the Galaxy, I really like that peach, and I'm not a big peach person, per se. But this nectarine is one of the best tasting in my entire orchard. That and the NectaZee.
Although my orchard looks lovely, and I have an additional row up on the top part of my yard, plus the entire front slope, the downside to growing here in S. California, is the plethora of birds. Mainly the Thrashers and the Mockingbirds. The Thrashers can wreak the worst havoc, with their long, hooked beaks. I have to net my figs, especially. That, and PLC. My two biggest threats to fruit. The great thing about Artic Star - it makes so much fruit, at least I get a decent amount, lol! That, and the Galaxy. Just incredible performers and delicious, high quality fruit.
The Artic Star is SO vigorous, I could have about built a house already, from all the pruning. And, it's on Citation, which is supposed to be, "peaches & nectarines dwarfed to 8-14 ft." Hah. I have taken out branches that are almost 3" in diameter, and have severely pruned this tree 3 seasons, now. It would be 30' tall by now, if I didn't take my large pruning saw to it every winter. I will say, I do love what this rootstock imparts to the fruit. It really is an excellent rootstock, of all the ones I have in my garden. And, another very perplexing thing - this cultivar is not really low-chill. I'd categorize is as a "mid-chill" cultivar. DWN says 500-650 ch. For me, anything over 500 ch is getting in the experimental zone-pushing arena for me. My Red Fuji, which is probably about 500 ch, shows typical signs on not receiving enough ch, with large spaces between leaf nodes mid-branch, poor fruit set. So, why this cultivar performs so spectacularly for me, is a bit of a mystery. But, I'll take it!
