Tea Olive for Fragrance

It could happen in the garden district of New Orleans or on Grandma's back porch in Mississippi. You stop and sniff.

What is that wonderful smell? Is it a rose? Or is it jasmine? Maybe a gardenia?

You look for blooms. No luck. Sniffing like a bloodhound, you finally run into a dense evergreen shrub, and there, tucked away in the deep green foliage, are clusters of tiny flowers. You have discovered the sweet Tea Olive, and you will never forget the fragrance. You are enchanted for life.

Tea Olives (Osmanthus) grow in the Deep South and other parts of the country in hardiness zones 7-10. Another name is False Holly, and they do look similar to hollies but can be easily distinguished by looking at the leaves. Holly leaves grow in an alternate pattern, while tea olive leaves grow opposite each other. Osmanthus heterophyllus is also called holly tea olive. It is one of the shorter varieties of tea olive. 'Goshiki' is a variegated cultivar I grow in my garden. There are many varieties. With a naturally upright shape, plants may reach 6 to 30 feet tall, depending on the type or cultivar. They are often used as screens or hedges, but they may also be featured as specimens. Osmanthus fragrans is another type of tea olive I grow. This is a young specimen. In a garden setting it should have a slow to moderate growth rate to 6-10 feet tall and about 5 feet wide, though ultimately it could reach 20 feet.Some make beautiful small trees, while others can be maintained as low as 4 feet. Be sure to check the ultimate size of the shrub before planting, so that you get the right cultivar for your needs. All have tiny fragrant flowers, which can be creamy white to gold or orange.

If planted in the right location, these are great low maintenance shrubs, which is why I have chosen them for my garden. They have a naturally pleasing upright form, and pruning is optional, though one may prune them in early spring to encourage lush growth or to maintain size. They adapt to many soils, though they are happiest in moist, well drained, acidic soil, the type of soil also loved by azaleas and camellias. 

They are tough plants that thrive on neglect, though I do fertilize in spring with an organic fertilizer for acid loving plants. Once established they are moderately drought tolerant, and they are also pest, deer, and disease resistent. They like sun to partial shade; in deeper shade they may be spindly and not produce as many flowers. 

Hummingbirds and butterflies are attracted to the flowers. Most tea olives bloom from September through fall, and in some locations through the winter. One type, Osmanthus delavay, produces spring blooms. If you choose to prune this one, be sure to do so after it has finished blooming in spring, to avoid cutting off the flowers. 

Tea Olives are long lived, enduring, and sweetly enticing; it's easy to understand why Osmanthus is a traditional symbol of romance. I am hopelessly sentimental, and I can't imagine my garden without these delightful shrubs.

I Love Yew

I fell in love with yew years ago when I visited a garden with an enchanted path meandering through a tunnel of yews. The deep green plants were vase-shaped, growing upright with upper branches that arched over the path. The understory was planted with all sorts of ground covers and woodland plants. It was a cool and leafy passageway that eventually opened to a sunlit grassy area with perennial borders and a pond. The image is still vivid in my mind. I have never recreated the scene in my garden, but I have planted some yews which are beautiful in their own setting.

There are many yew cultivars. Some are tree form, growing to over sixty feet tall. Others are low growing spreaders that make good ground covers. Many are shrub-like and can be clipped into hedges. There are English yews, Taxus baccata, and there are Japanese yews, Taxus cuspidata. And then there are combinations of the two, Taxus media

All yews have short, flat needles that are dark green on top with lighter green undersides.
New spring growth is a fresh green color.The plant is evergreen and looks best when combined with lighter shades of green and colors such as gold, silver, blue, and burgandy. The following photos show how the deep color of yew combines with the chartreuse of my moss path, as well as the lighter foliage of the Japanese maple 'Waterfall', shown in the first shot.

Yews like sun to shade and once established are drought tolerant, growing in hardiness zones 4-9, depending on the cultivar. They like well drained, neutral soil. Emphasize the well-drained part. Usually yews are unbothered by disease or insects, though occasionally scale, weevils, or root rot may affect them. Yews don't do well everywhere on my property. In fact, I have killed several by planting them in clay soil. But in a particular part of the Woodland Garden the soil is rich and deep and nearly the color of charcoal. Here I planted two low growing, spreading yews, Taxus Baccata 'Repandens', and they have thrived. After about five years the two cover an area of about fifteen feet. They anchor a corner of the woodland's main planting bed and provide year round structure to this part of the garden. One can see them in the lower right corner of the following photo, taken in March 2010, before most other plantings in the area had leafed out or begun to grow.

Be aware that all parts of the yew plant are poisonous. Female plants may produce attractive red berries if a male yew is in the area. If yews grow too large or ungangly, they can take severe pruning, but thus far I have not pruned mine. They truly have been low maintenance plantings. I can't help loving yew!
