Thanks for your response! Sadly I don't really know if Borneo Red is really from Borneo. I just happen to find the variety at a nursery, but haven't gotten it yet. I'll try Papaya Tree Nursery, but it seems hard to get plants from Alex. I believe you have to make an appointment, and from my experience it doesn't seem like he has the plants I'm looking for in stock. Have you ever purchased plants from him?
Thai jumbo is the sweetest one I've ever tried. Unfortunately it takes years before it can bear fruit.
I never heard of Borneo Red, is it from Borneo?
Alex from Papaya Tree Nursery has an unknown variety that is sweet, productive, and precocious. Plenty of fruit in a 5 gallon.
Other varieties like Black Pearl, Black Diamond, or Black Kingkong are depends on the growing conditions. I tasted super bland and tasteless Black Pearl grown in El Monte, but a pretty good ones from another source in Arcadia
Yes, I've purchased many plants from Alex, and I am happy to say all plants I got from him are healthy and productive.
To purchase the plant, usually I will email him first explain what I want, then ask to put me in the waiting list if it is not available. Usually it takes 6 months for him to graft or airlayer a plant.
One thing I know, he won't sell a plant that is not 100% ready.
You can visit his nursery by appointment, during the covid is actually easy to get same day appointment. I visited him twice during the covid. Face mask required and he will maintain 6 ft distance with you.
He knows a lot about tropical plants, he will explain how to take care of each plant for hours. One thing I really like about purchasing from him is, he is honest. If he thinks it won't do well in your zone, he will tell you.
