Marrow Stem Kale

These varieties are more tender and better flavored than the Scotch Kales. They aren't as hardy, however. Very young leaves can be used raw in salads though they are usually cooked (stems may be tough or not, depending upon circumstances). A biennial, in the spring the flower buds can be used like broccoli.

Kale is a hardy green leafy vegetable harvested in late fall and winter. It develops it best flavor under cool growing conditions. It can also take some light frost allowing it to make it through mild winter weather.

Spring Kale will actually grow right through the summer, but doesn't taste as good when growing at higher temperatures. It is more tender and sweet in cold weather.

In mild climates, kale will continue to grow all winter without disruption and can be harvested continually for months (it will also be in peak condition in the cool weather).
