After reading site I can say only that most Black Beauties Ive seen in Azerbaijan (former Northern province of Persia / Iran) were not Morus Nigra. Pictures published here are not pictures of Morus Nigra. I ordered from Turkey grafted plant under name Morus Nigra v. Yediveren but according to Turkish scientists it is Morus Alba, see the table at

Dwarf Everbearing with black fruit is not Morus Nigra.

I have scoured the internet to find the correct USDA zone for M. nigra. Dwarf Container Black Mulberry. Most sellers and experts (Lee Reich) say this is not hardy like M alba, and is zone 7-10 at best. Many sellers, however, call it zone 5.
When asked why, they say it's because their supplier (Agri-starts) calls it zone 5. When Agri-starts is asked why they call it zone 5, they say Dave's Garden calls it zone 5.
So I believe everyone on the internet is ultimately relying on Dave's Garden, when they call M. nigra good to zoned 5. And I believe that is incorrect.
I hope we can settle this one way or the other. Remember, "Black" mulberry does not refer to the fruit, but the buds. White Mulberry, M. alba, is common throughout the US, and has black fruit. M. nig... read more

The fruit of Morus nigra is said to be much tastier than that of M. alba, which is much more common, and which many find to be insipid (myself included).

This is less hardy than the invasive M. alba, and is often listed as reliably hardy only to Z7, though there are cultivars like 'Wellington' hardy to Z5. It has been cultivated in western Asia and Europe for milennia, but its origin is shrouded in mystery. It is a polyploid, and has not been found in the wild.

Silkworms eat M. alba leaves but cannot feed on M. nigra.

It's claimed that M. nigra generally does not produce viable seeds. BONAP indicates that it's naturalized in 6 states: OH, KY, WV, LA, NV, and CA.

I love the persian mulberry fruit tree. The fruit it short and fat and tart before ripe. The darker the fruit ripens, the sweeter it will be, Once ripe the fruit has amazingly unique sweet and juicy with great flavor. It is a very vigorous tree with heart large shaped leaves great for shade. The persian mulberry tree is very popular at

ONCE YOU GO BLACK YOU'D NEVER GO BACK. This black mulberry is so much better than the red, that I can't figure why anyone would plant a red mulberry, except they never tried a black one. It is very sweet, but also a little tart like a dewberry, or a really good blackberry with no detectable seeds. It grows very well in zone 8b where I live. My 3 year old tree is 15 ft. tall and bore fruit the second year. I hope it continues to grow well because I planted 4 more trees after I had a chance to taste the fruit. It doesn't seem to be as invasive as the red variety or there would be more of them around.

The Persian mulberry is a large 3 inch blackberry-like fruit that is dark purple to black. It is excellent for fresh eating or jam. The Persian Mulberry makes a large 25-30 foot tree with dense heart-shaped leaves.

We had the first large crop from our young tree last season. There was a net placed over the tree to defend it from the birds and fruitbats, which worked to some extent, although the blackbirds and mynahs were willing to risk entering along the ground and being trapped to get at the fruit. It is large and luscious and when fully ripe as sweet as can be. My personal preference is for slightly underripe berries which are less sweet but have more flavour. The berries went into sauces for ice-cream, jams, onto cereals in a morning and every berry recipe I could find. (Muffins were a particularly big hit). But overall the kids' preference was straight from tree to mouth.
It is probably a tree for a large garden as its growth habit is an insane tangle (or you could buy the weeping form) ... read more

tree grows vigorously and wildly, loses leaves in winter. fruits from about mid may through august, heaviest in late june. fruits make a big mess so plant away from house or you will be tracking black staining juice on your carpet. fruit is sweet but flavor is non descriptive.

silk caterpillars (in India) are reared on an exclusive diet of fresh green Mulberry leaves up until the time they begin spinning their cocoons. Sometime in the '70, I was given a tray full of caterpillars for a biology project in school. These came from a "silk-worm" farmer, and complete with a supply of favourite-diet branches and leaves. I must have stuck one of those branches into the ground in a corner of the garden. Today, we have a LARGE and unruly Mulberry tree. No silk-caterpillars, of course, but the birds - Bulbuls, Crows, Cuckoos - love to squabble over the fruit. We let them have it all since the slightly tart berries are decidedly more suited to harvesting by beak!

My grandpa had a Black Mulberry tree. I spent my vacations in his house, and used to eat the berries a lot, being pure, or as jams, juices, pies... I always knew I would get loads of those delicious berries when I visited him. But then the tree died, and I never ate it again.

12 or 13 years later, during a trip, I found around 10 Black Mullbery Trees growing together, and they were loaded! I got my fingers, my lips and my tongue purple with their juice. It was nice. I wish more people would grow it here in Rio de Janeiro. This is not the kind of fruit that can be transported to supermarkets and all, the only wat to get them is by picking them from the trees.

FAst growing, fruit bearing tree used extensively in Lebanon, Jordan, Iraq, Iran and the Arabian Peninsula. The trees bear fruit in late spring. In Lebanon, juice and ice-pops are made from this fruit and it is a welcomed treat on a hot summerday!
I find them a bit messy when the fruits begin to drop as they are staining. Birds love to eat the fruits.
The fruits make nice jams and jellies.
