If I have a choice, I like to add some color to my garden. Kale gives color options with different varieties.
Check out these options for a pop of color in the leaves, stems and veins:
Dazzling Blue
Redbor
If you want frilly leaves and a pop of color, then check out:
Feathered Frills
Scarlet
Red Ursa
If you prefer green, then try the following:
Premier
Lacinato (Dinosaur)
Tronchuda
Meadowlark
White Russian Kale
Siberian Cale
Just like my seed ideas for bok choy, you can find these seeds at Baker Creek, Botanical Interests, High Mowing Seeds and/or MIGardener. This year I am growing some kale from a Premier Kale Blend from Botanical Interests.
