Camellias

             
Camellia sasanqua


            Camellias are perfect for filling in the gap between late summer and early spring flowers.  Starting in October, Camellia sasanqua begins a delightful show of rose-like flowers.  Blooming continues through January. Later in the winter season, Camellia japonica starts its show and blooms as late as April. Under ideal conditions, camellias can bloom 6-8 weeks and survive for generations.
       
     Most plantings in my yard were experimental. 19 years after they were planted, my camellias are a success story. I planted 3 Camellia sasanquas in different locations around the house. Due to varying microclimates, each camellia blooms at a different time. This allows us to enjoy each bush individually in its glory. Microclimates are caused by location-related variables that affect plant growth.  Examples are sun and wind exposure, warmth or protection from a brick wall, rain off a gutter, and soil drainage or slope conditions.

     Camellias are available in white and various shades of pink and red.  Select the healthiest plants from reputable suppliers.  New cultivars and hybrids with double blooms and increased winter hardiness may be available.  Alternatively, camellias can self-seed near a mother plant.  Check with your gardener friends to obtain a free plant.




     Camellias are perennial evergreen bushes. Each year the number of flowers increases with the size of the bush.  Keep the future tree-like proportions of a camellia in mind when choosing the planting site.  Like azaleas, camellias prefer acidic soil of 5.5-6.5 and partial shade. Many area soils are naturally acidic, but you can have your soil tested through your county extension office. 

     I have found camellias to be low-maintenance plants.  There is little deer or insect predation.  They grow big enough to offer cover for birds visiting a bird feeder. Place the feeder far enough from the camellia so it can’t be used as a launching pad for squirrels.  Prune wayward branches and unwanted growth after blooming in late winter or early spring.

     If you’re already a camellia owner, take the time to appreciate this winter color, and, if you’re not, plan on obtaining one soon.

Stunning White-marked Tussock Moth Caterpillar



White-marked Tussock Moth Caterpillar




     This colorful caterpillar feeds on a wide-variety of trees. Severe defoliation of trees can sometimes be attributed to this species. An allergic reaction may result from touching the hairs.

There are several caterpillars with "tussock" in the name. This refers to tufts of hair. Their appearance features tufts of hair rather than a uniform covering of hair.

     The White-marked Tussock Moth is related to the Gypsy Moth so a fungus introduced to control the Gypsy may affect the Tussock.

Saddleback Caterpillar: Beautiful Camouflage and Painful Sting



The Saddleback caterpillar has a striking appearance with a bright green body and a brown saddle. Horns point upward on either end. Spines on the horns and other hairs secrete painful venom.

Ive brushed my leg against a Saddleback and can attest to the discomfort. Upon stinging, the spines can become lodged in the skin which causes more venom to be released and additional irritation. Loose spines can be left on surfaces or be inhaled posing further hazards.


I photographed this specimen on a Japanese maple tree. The caterpillars movements were slow, but deliberate. It's about 1 inch long. The Saddlebacks host plant list is lengthy.

This caterpillar is classified as a slug caterpillar because it does not have prolegs and moves in a sluglike manner. [Prolegs are fleshy protuberances that aid with motion in other caterpillars.] It is the larvae of a brown moth called the Saddleback Caterpillar Moth.

My Favorite North Carolina Wildflowers


Asiatic Dayflower



The bloom on the Asiatic Dayflower is only 1/2 inch long. Upon close inspection, it's a beautiful royal blue flower resembling an orchid. The foliage consists of healthy green leaves that tend to be invasive. My crop appears in clusters along my gravel driveway.The name alludes to the fact that blooms appear only during the day .

White Yarrow



I seldom see the blooming on my White Yarrow, but the feathery, fern-like greenery is a favorite of mine. I had a cluster start along my garden gate, and transplanted some of it to other areas. I've heard it described as invasive, but that hasn't been my experience. One of my reference books calls this plant Common Yarrow.


MYSTERY PLANT-CAN YOU IDENTIFY?


This plant has small delicate lavender flowers mounted on top of a triad of fuzzy leaves. It is blooming now (August in North Carolina).


At the base, large leaves lie flat on the ground. A stalk grows about a foot tall and holds the flower stems.


This image shows a group of the flowers clustered among my azaleas.

I have checked my reference materials, and have been unable to identify this plant. It may be in the Plantain family. Please comment on this blog if you know the name.
