Yes! They get 2 hang lamps of their own right now, About 10” above and a radiant light heater directly on them that provides mostly heat, but a TOUCH more light...Palo verde, from seed. I've always loved seeing the various palo verde when visiting Texas, Arizona & California. I know I was looking at 3 or more different species of Parkinsonia, but they all get called palo verde. The "beans" are edible too, especially harvested green, and then boiled as for lima beans and other bean crops.
The fact that Palo Verde is leafless most of the year is interesting. It will give you a winter silhouette pretty much year round. The issue I see will be giving the Parkinsonia enough sunlight and supplemental light in winter to keep it healthy. It is a desert plant, adapted to, and to some extent requiring blazing full sun. I'll be curious to see how these do for you.
Hybrids? Yes. Sterile? Not necessarily.I thought grocery store apples we're usually sterile hybrids?
Yes! Smaller orchards like this, after inquired about, are said to operate on an entirely different scale... THIS particular one utilizes Air-layering instead of “Rootstock burrowing”... I noticed the “set-ups” on some of their trees, so I asked...Hybrids? Yes. Sterile? Not necessarily.
I thought most commercial stock was grafted for "conformity". Hybrids do not generally produce identical-to-parent offspring. When growers find a good tasting, long shelf life, marketable color apple, they graft cuttings so that all trees are clones and the fruit is consistent. That doesn't mean the seed is sterile. The seed may very well grow crap apples, however. Not generally a concern in bonsai...
