African violets

                        AFRICAN VIOLETS                             (Saintpaulia)

Flowers have five petals with yellow centers.

African Violets have long been the most popular flowering houseplants in the country and will continue to maintain this distinction far into the future. African Violets are not  "true" violets but are a genus "Saintpaulia"  related 

to Gloxinia, originally from Kenya and Tanzania, Africa.

New varieties have flowers that can be ruffled or multi-colored.

One reason for its popularity is its ability to flower in indirect light and easy care. African violets are short plants with rounded or slightly pointed leaves with flower  stalks emerging from the center. Flower colors range from white, pink, red, purple and blue with a yellow center. There is also a trailing variety which is less well known. Flowers have five single petals although now double flower are available as well as fringed and multi-colors varieties which seem to be created every day. Even variegated leaves of white and green can easily be found.

 With short periods of rest, Africans violets flower throughout the year.

The abundant flowers bloom well with indirect sunlight all year long which help make African violets as popular as they are. They also prefer modern indoor temperatures of around sixty five degrees which is ideal. Most houseplants prefer cooler temps at night. Additionally a fully mature plant only requires a three to six inch pot making them ideal for window ledges, shelves or coffee tables. All these traits make African violets perfect flowering houseplants for almost everywhere in an apartment or house with enough indirect sunlight or  artificial fluorescent light.

Use the correct size pots as plants grow to help the roots to adjust.

Considered an easy to care for plant, it is important to remember that African violets come from a warm climate. Water them with room temperature water. Cold water causes yellow spotting on the leaves . Also avoid wetting the leaves when watering. Watering plants from the bottom is a good practice and lets them dry out between watering. Over-watering can cause root rot, the most common cause of death of all houseplants. Also avoid drafts. Move away from cold drafty windows and air conditioners.

Easy and fun to propagate, you can take a leaf with the stem from the center of the plant and root it in water or potting soil. The outer leaves are too thick and do not root easily. Once rooted African violets grow quickly to flowering size.

Once plants have rooted it's time to move them into the soil. 

Off shoots from the main plant are best removed and to their own pots.

Requiring a rich soil mixture, you can purchase African violet soil premixed or you can *blend your own, but they will not grow well in regular potting mix.

As the new plants grow you can add them to your collection or give them to friends as gifts.
African violets are excellent Mothers Day gifts.

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.
