Ornamental Kale


ORNAMENTAL KALE
FLOWERING CABBAGE 
Brassica oleracea


Plantings of Ornamental Kale and Flowering Cabbage add
drama to this city scape on a rainy winter day.

After Chrysanthemum flowers fade away and squirrels have eaten the pumpkins, ‘Ornamental Kale’ or ‘Flowering Cabbage’ still brings color to the late autumn garden. These beautiful plants are prized for their brightly colored foliage which becomes more intense when temperatures drop below 50 degrees. 



As the tempatures drop,below 50  colors in the leaves become more intense. 

Ornamental Kale is in the same family as cabbage, broccoli, cauliflower and collars.  Although flowering kales are edible*, it is not delicious and is best used as a garnish on the bottom of the plate.



Flowering cabbage is easy to indentify by the rounded leaves with
resemble our common ediable cabbage. 


When you buy Ornamental kale at your local garden center select plants close to the size you want them when mature. Once root bound they will not grow much more than they already have in the pot.




Ornamental Kales have many different leaves with more being introduced every year. 

When you bring it home, plant them in the ground or transplant into another pot. Bury stems so that the lowest leaves are flush with the soil surface.
Ornamental kale requires a sunny location in a moderately moist rich soil.        Keep the plants moist. Kale and cabbage do not do tolerate drying out and will lose vigor quickly. Fully grown plants are approximately 15 inches tall and one foot wide.



The key to longivity is regular watering. 

When colder weather arrives pigments in the leaves will brighten, white pink or red. This is when they at the peak of their display. In addition to color kale leaves have many shapes, curly, frilly or ruffled.




The pure white leaves of this Kale would be the focal point of any winter garden. 


There are many different cultivars available today, ‘Peacock’, ‘Pigeon’, ‘Osaka’ and the ‘Tokyo’ to name a few. Home gardeners have a large selection to choose from. Pick the plants most pleasing to your eyes.



It is the colors and patterens on the leaves of Flowering cabbage  that gardeners find appealing. 

You can start seeds ten weeks before the expected frost date or purchase plugs at your local garden center. Growing them can be fun but you will have to battle beetles and insects to prevent them from chewing holes in the leaves. I only have space for a few pots so I use this opportunity to support my local garden nurseries.



If they survive the winter both the kales & cabbages will flower in the spring.

*As noted above, ornamental kale and flowering cabbage plants are edible, but they are tough and bitter.  To reduce their bitter taste, boil them, discard the water and then boil or sauté them in olive oil prior to serving.
