Torenia: My New Shady Lady

Fig. 1    Torenia fournieri

Every year I try one or two new plants in my garden and this year one of them is Torenia (Torenia fournieri). Torenia, commonly called 'Wishbone flower' is a beautiful annual plant that performs best in the shade. The tubular flowers come in shades of pink, yellow, and blue on the lobes - depending on variety. The tube often comes in white with a blotch of yellow in the interior of the lower lobe (Fig. 1). The plant grows up to 12 inches tall and wide and blooms continuously in summer until temperatures drop to freezing point.

Torenia is generally easy to care for.   For best results, plant it in the shade and where the soil is fertile.  Keep the soil moist especially in hotter weather condition.  Pinch young plants to induce branching for a more bushy appearance of the plant.  Fertilize regularly with complete fertilizer to promote profuse blooming. When growing torenia in containers, put container-plants together to create a shadier and cooler environment (Fig. 3).

There are no known serious insect and disease problems but they could be susceptible to powdery mildew and possibly root rot - depending on soil.

Torenia is giving me a positive first impression.  So far, it will continue to have a place in my garden as an annual plant (replacing impatiens) until I find a better one.

Fortune Plant (Dracaena fragrans)

Dracaena fragrans 'Masagaena' in bloom.

Dracaena fragrans is one of the most important houseplants in the United States because of its ability to tolerate low-light environments and low maintenance.  In the Philippines, it is grown both as an indoor or outdoor plant.

This plant is known by so many names and for different reasons. With its broad and elongated leaves that resemble that of corn (Zea maize), Dracaena fragrans is nick-named corn plant or cornstalk plant in this part of the world.  On the other hand, its botanical name indicates a significant olfactory characteristic - "fragrans".  This plant's ability to exude sweet odor outweighs all other characteristics that it is used to universally describe the species of the plant.  With such names we could say that this type of dracaena is a fragrant corn-looking plant.  However, in some countries it is called 'Fortune Plant'. There is a superstition that revolves not just in the Philippines but in the rest of Asia.  If the plant blooms in your care, then good fortunes will abound in the home.  The blooming time seems to be unpredictable that people associate it with the elusive incidence of good luck. :)

Dracaena fragrans is sometimes called Corn Plant.

For me, it is not uncommon to see this plant bloom. My mother had one that bloomed outside her front door year after year.  Everyone who came to our house after dusk knew it was in bloom even if they didn't see the flowers.  Here in my house (in California), there are three potted Dracaena fragrans - one of them is about eight feet tall and the other two are about six feet tall - all of which I've had for years now.  I purchased these plants at different sizes.  It has been my observation that only the mature plants - with a minimum trunk diameter of one inch- showed flowers.  However, not all plants with the same size of trunk bloomed.  One of my plants did not bloom this year even if it has larger trunk than the other two that bloomed.  Therefore, I have to come up with another theory -- that the plant has to be exposed to not one but a combination of critical factors prior to flower initiation. I think the plant blooms when they reach a certain age and accumulated experience.  How to quantify such variables remain unknown to me.  I'm sure there are scientific literature out there that explain this mystery.  But before I find them, I will enjoy the secret belief that my Dracaena fragrans is signaling the arrival of good fortune into my house.  :).

Dracaena fragrans line a village road in Cagayan,  Philippines.

Traditions, superstitions and beliefs determine the way cultures look at plants.

Rosa 'Abraham Darby'

'Abraham Darby' is an English rose that was bred by David Austin. The flowers come in pinkish apricot color with a fruity fragrance and the leaves are small-sized and glossy. The plant is a vigorous medium sized bush with arching growth habit. Some consider it as a small climber but in my garden I prune it often both to keep the size in check and to encourage blooming. In my garden, I find 'Abraham Darby' resistant to black spot and powdery mildew.

'Abraham Darby' rose was named after an inventor who played a significant role in the industrial revolution. In the smaller world, however, this plant made it into my garden in honor of my son who is nicknamed Brahms. :)

Regardless of the name, Abraham Darby is a garden-worthy rose!

The Robin and the Worm

An American Robin (Turdus migratorius) gets the worm - early in the morning.

Baby Blue Jay

Baby Blue Jay

Blue jays (Cyanocitta cristata) seem to consider our garden as a prime location for building nests. Previously, they had a nest on the lemon tree and on the Cecile Brunner rose that was by our front door.  But the best so far was when they had a nest on a three-foot tall standard rose in the backyard.  My two older kids, who were then very young, looked at the eggs every day.  This year, our resident blue jays built another nest on the grape arbor.  My daughter (younger) watched them as they gathered twigs for the nest.  She observed every activity there - touched the three eggs and then heard the little baby blue jays claim their worm every feeding time. When the nest became too small for them and the mommy bird prodded them to fly but one of them was still too weak to take flight. It fell to the ground.  We put it back to the nest that night but soon we saw her in one of the bushes where she was safe.

Getting ready for the first flight.

It is amazing to watch the birds take care of their young - they are like humans in the way they teach their kids - one lesson at a time.  The other day I watched the parent blue jays teach the babies to splash water from the bird bath.  It was amusing.

Out of the nest for the first time.

 Attract the blue jays to your vegetable garden with corn or peanut seeds.  And they will eat all your tomato hornworms too.

Growing 'Woolly Rose'

Fig. 1    Woolly Rose (Echeveria cristata 'Doris Taylor') flowers

Every summer in my garden, the Echeveria cristata 'Woolly Rose' (a.k.a. Echeveria 'Doris Taylor') sends out colorful flowers that look like candies.  The rosette foliage of this plant is covered evenly with a thick mat of trichomes that gives it a velvety appearance - thus the name Woolly Rose.   Not only the plant is beautiful but it is also a source of nectar for the hummingbirds (Fig. 2).  Whenever my plants bloom, I move the ones that are in pots to a place where we can enjoy the view from the kitchen window.  

Fig. 2    When in bloom, Echeveria cristata is a hummingbird magnet.

Tips in Growing Woolly Rose 

1.  Soil.  Plant Woolly Rose in the garden where the soil is well drained.  Improve drainage of clay soils by adding sand or pumice in planting area.  In containers, use cactus mix for good drainage and weight.  Adding good amount of Perlite and sand to regular potting soil works as well.  

2.  Sunlight.  Woolly Rose is adaptable to a wide range of environments but the plant will look its best in the right place.  In the summer (Zone 9), position Woolly Rose where it will get a few hours of morning sun or a short period of afternoon sun.  Too much exposure to sunlight will result in washed out yellowish color of the leaves while too little sunlight gives relatively greener foliage and longer internodes.  The right amount of sunlight will give the plant a bluish green color and compact rosette foliage.  Contrary to popular belief, succulents thrive best in partly shaded environment.

3.  Water.  The plant can tolerate periods of dry conditions but they grow faster and look better if they get adequate water.  Adjust watering based on the weather.  Watering is needed more frequently in summer and spring time, when the soil dries up faster, than in the cooler months of fall and winter.  The size of container is also a factor to consider when it comes to watering.  Plants in smaller containers require more frequent watering than those in larger containers/

 4.  Fertilizer.  Woolly Rose performs better when it gets sufficient soil nutrients.  Although the plant does not need a lot of fertilizer, it is responsive to fertilization during growing season.  A low dose of complete fertilizer is all the plant needs.  Succulent/cactus fertilizers (2-7-7 and 1-7-6), available at local nurseries, are easy to use and can be applied as often as every other week.  

5.  Protection from Frost.  Woolly Rose is easy to grow - the only problem, especially where I live, is the susceptibility of the plant to frost damage.  In areas where freezing temperatures are expected, protect the plant by moving them to a sheltered area.  With a little bit of protection this plant will continue to provide a delightful touch in the succulent garden.

6.  Propagation.  The plant is easy to propagate through cuttings.  Stem cuttings collected under the lowest leaves are the fastest to root.  Collect and stick the cuttings where there is a little bit of moisture and warmth. Figure 3 shows Woolly Rose growing from the sides of an orchid plant. Cuttings were directly planted into the holes.  Some succulents can be easily propagated from the leaves but this is not the case with Woolly Rose.

Note:  Extreme temperatures, drought, and nutritional deficiency are conditions that can cause stress to Woolly Rose - all of which can contribute in the loss of the basal leaves and exposing a dark brown stem (Fig. 4).   However, this is not necessarily alarming.  In fact, this is a natural process that gives that plant an aged look.

Radicchio in my Kitchen Garden

Radicchio (Cichorium intybus) made it into my vegetable garden when my husband sowed (literally poured) a packet of Salad Greens seeds in between tomato plants last summer (2013).  The seeds emerged quickly, produced healthy foliage till they began to bolt and produced flowers.  Autumn came; one type of the greens continued to grow and did not bolt.  Then winter came; the leaves of this plant began to form heads - like that of cabbage.  The new leaves also began to turn wine-red in color.  It was then when I began to wonder what this plant was - Radicchio!

When Monocle Magazine named radicchio Vegetable of 2014, I was determined to keep a close observation on these curious plants growing in my garden.  The mildly bitter and vibrant red radicchio is considered a super food due to its high antioxidant content.  It was tempting but I resisted harvesting them.  At this point they were more valuable as a learning tool than food.

Spring came and the radicchio heads began to unfurl and flower initiation began.  The plant finally began to bolt.  The ground-hugging salad item suddenly turned into seven-foot flowering plant.  Beautiful blue flowers opened every morning and faded in the afternoon.  This scheduled flower opening made the bees busy during the cooler time of the day.  Indeed, radicchio is a good insectary plant.  Being a member of the Asteraceae plant family (commonly known as aster or sunflower family), the flowers are designed in such a way that insects can land on them with conveniently.

 Plant radicchio for food, beautiful flowers and insectary plant.
