Red mulberries are different from the other common mulberries species in that they are native to a climate that is consistently wet and are often seen growing as an understory tree. Rainfall can be between 0.5" to 5.5" per month throughout the year, but it generally reside around 3" to 4" during the grow season.

White mulberries are native to China. I have not found any other details on its range, but based on their cold hardiness and ability to thrive in a semi-arid climate, I would guess that its predominately in the north and seeps into the wetter areas to the south and east, since some cultivars are known to thrive in wet climates as well.

Morus alba is considered to be an invasive species in many parts of the US, and their fruit have the least complex flavor of the more common species, but some can be very sweet. Some believe the flavor of certain cultivars, including alba x rubra hybrids, are highly reliant on the climate they are grown in, with wetter climates being unfavorable. A lack of flavor, or a grassy flavor, may also be due to early picking.

Black mulberries are believed to be native to the mountainous region Mesopotomia and Persia (Iran). The climate within their range is mediterranean, semi-arid, and may possibly include hot desert as well. Rainfall during the summer is virtually non-existent but will generally be between 0.5" to 1.5" per month during the rest of the year. I have only seen one report of seedlings thriving in a wet climate, otherwise, no one seems to bother.

Shahtoot mulberries are native to the Himalayas and the rainforests of southeast Asia. The climate is quite wet during 1/3 to 2/3 of the year (around summer) with rainfall ranging between 2" to 6" or more per month. The rest of the year is very dry.

Sweet Lavender is currently, by far, the sweetest fruit I have ever had, without intentionally trying to increase brix levels, and it may not have even been fully ripe (it was white rather than lavender). There was no acidity and it lacked a berry-like flavor, but it's still more interesting than alba seedlings, in my opinion. If you pick them while the edges are still slightly green, it will have somewhat of a grassy flavor.
