alpha, 'Triumph' is a named-variety of astringent-til-ripe Asian persimmon. It is the most widely planted variety in Israel, and the astringency in the fruit is removed chemically by some process using CO2, with them subsequently marketed as 'Sharon Fruit'. The CRFG Fruit Facts article you referenced confirms this I suppose any non-astringent variety could be treated similarly and sold as 'Sharon Fruit', but all I've ever seen in the groceries here were the flat, somewhat squarish, Fuyu-type, which I presume are 'Triumph'. I've checked my sources, and not been able to find a nursery that offers Triumph either, and it's not listed in the available accessions at the NCGR website(but I know they have more than they're showing - I've seen a list of 140+ accessions). But I've seen a number of technical papers that describe fruiting performance/sensitivity to ethylene, etc. in Triumph, compared to Giant Fuyu, Hachiya, etc.

The additional photographs make my first guess wrong. The size of the bush is really impressive (as is the health of the foliage). The redder edges of the petals in the additional photos should be a real diagnostic aid, but I don't think I've ever seen this rose before.

It looks a lot like my "Distant Drums" in bloom. Do the blooms change color as they age? My "Distant Drums" starts in a buttery yellow with the purple rim, but the blossom turns to a pale lavender as it ages. http://www.heirloomroses.com/roses/unusual-color-roses/distant-drums.html http://www.helpmefind.com/gardening/l.php?l=2.1538 http://www.thegracefulgardener.com/wp-content/uploads/2012/06/2012-03-30_4947_edited-11.jpg

I actually have not trained this Hibiscus as topiary but I can see the possibility that it could be trained like the one you have already seen. If your plant has reached the height that you desire I would simply pinch out the growing tip and remove the side branches but leave sufficient side branches near the top. This plant responds well to trimming so in no time at all wa-lah Hibiscus Topiary. Now you see you even got me going. LOL. Ankrara's Hobby Corner
