Turnip greens have quite a bitter taste and are known for their calcium content.
They resemble mustard greens (to which they are closely related) in flavor.
Turnip greens are a common side dish in southeastern U.S. cooking, primarily during late fall and winter.
Smaller leaves are preferred; however, any bitter taste of larger leaves can be reduced by pouring off the water from initial boiling and replacing it with fresh water.
Varieties specifically grown for their leaves resemble mustard greens more than those grown for their roots, with small or no storage roots.
These include rapini or broccoli rabe, bok choy, and Chinese cabbage.
Both turnip leaves and roots have a pungent flavor similar to raw cabbage or radishes that becomes mild after cooking. (source)
So can hamsters eat turnip greens?
Yes they can but don’t give them too much due to their calcium content but your hamster will enjoy them.
