Streptocarpus

Streptocarpus spp.

Inside Grandma's house a flower sits by the eastern window
Patiently it waits to feel the morning sun
But the sun has to traverse the canopy of the giant redwoods...
The time will come when the two meet again.
And yet it is not without difficulty for the Eureka fog often clouds the way. 
It stretches out its leaves to embrace the warmth of the magnificent brilliance of the morning.
The flowers blush as the sun's rays touch their petals.
Translucently delicate flowers float above the dark green scalloped leaves.
Grandma says - it has a name that sounds like a disease but the streptocarpus blooms all year.
With such gorgeous flowers it will surely brighten a gloomy day.
~ ~ ~

 There is something about that name.  One of the plants that caught my attention during our recent trip to Eureka was the Streptocarpus.   Although the name sounds like a strain of bacteria that infects the throat, this plant is safe to touch.  The name Streptocarpus comes from two Greek words (streptos which means twisted; carpus which means fruit) which refers to the twisted seed pod of the plant.   The twisting happens during the development of the pod as in the spiraling of tendrils.  Differential cell growth and interplay of plant hormones are responsible for this type of development in plants for a reason.  It appears that the twisting of the Streptocarpus pod releases the seeds as a natural mechanism for dispersal.   It's amazing to know that the God of the universe made sure that even this tiny plant was given a blueprint for a perfect life. 

Trivia question:  What bacteria family looks like a twisted string of beads when viewed under a microscope?   (Clue: Greek word kokkos means spheres or berries)

Flowering Crabapple

Flowering Crabapple Tree (Malus floribunda)

Ornamental and Shade.  This beautiful crabapple tree blooms profusely every year.  It provides an early spring pink color in the backyard.  Not only it is delightful to look at, it is also very easy to grow and makes a good shade tree as it is fast-growing.  In my yard the crabapple is planted near the patio contributing to the much needed shade in the summer. 

Pollenizer.  A number of the apple trees are self-fertile (capable of producing viable pollens) while some are cross pollinated and would require another apple tree of a different variety as the source of fertile pollen.  The flowering crabapple is an excellent pollenizer for other apple trees.  An important factor to consider in choosing your apple varieties is the time of flowering.  The apple tree and the pollenizer tree (source of viable pollen) should bloom at the same time.  In my yard I have a Fuji apple that bears fruit every year (never mind that half of the fruits are infested with codling moth (Cydia (Laspeyresia) pomonella).  The only other apple tree nearby is the crabapple.  I would say that they are compatible.

Update on the Vegetables

Defoliated pepper  (Capsicum annuum) seedlings

About two weeks ago, I had healthy seedlings of peppers planted in my garden.  Now they are all defoliated like the picture above.  Finch birds have been eating them.  Last year, they ate my eggplant seedlings too.  I had to replant them and covered them with clear large soda bottles until they got tall enough for the finches.  I could wait for these poor seedlings to leaf out but that would be wasting too much time.  I will replant and make sure to protect them.  The birds also ate all the radish and bok choy seedlings which my daughter Miriam started from seeds. 

Cilantro (Coriandrum sativum)

These cilantro are planted next to the peppers.  Can anyone argue if I say that finches are a little bit picky when it comes to their salad?  They don't seem to like cilantro leaves.  However, when the seeds called coriander are ready, it will be a different story.  Anyway, I'm very pleased with the way my cilantro are growing right now.  I just hope that they will not bolt quickly.

Tomato (Lycopersicon esculentum 'Better Boy Hybrid')

Although finches also like tomato leaves, these plants were taller than they can reach.   One tomato plant behind these two is a smaller and they managed to eat its lower leaves.  These tomatoes are just waiting for the temperature to get warmer now and they soon will leap.  'Better Boy' is an indeterminate hybrid tomato.

Indeterminate plants are those that produce flowers on the lateral buds allowing them continue growing for extended period of time.  As long as they continue to grow they will still continue to produce flowers and fruits.  Determinate plants bear flowers on the terminal buds.  Once flowers begin to develop, the plant stops growing.  The life cycle of a determinate plant is shorter than its indeterminate counterpart.  Since we have a long growing season in California, I prefer indeterminate varieties.  However, in other years, I planted determinate tomatoes and then planted a different crop during late summer or early fall.

Mint (Mentha spicata)

These are spearmints that I started from stolons three weeks ago.  Since they are very easy to propagate, I often start new plants every year and replace the root-bound plants from last year.  Unless you are growing mints for commercial purposes, it is a good idea to keep your mints in pots.  Once in the ground and left unattended, it will take over your garden. 

Potato (Solanum tuberosum)

I planted potatoes once and every year since then we have volunteer potatoes in the garden.   They come from the tubers that were left unharvested from the previous crop.   I could pull them out or wait for another month and we'll have young potatoes for boiling.

Other vegetables that a in the ground but have not emerged are basil (Ocimum basilicum), beans (Phaseolus vulgaris 'Maxi') and luffa (Luffa cylindrica). 

Well, I need to stroll in my vegetable garden more often and try to outsmart the birds.

Cyclamen

 Cyclamen persicum

Inspired by the sight of the beautiful cyclamen on the table out in my patio, I decided to post this old old poem about the plant.  It demonstrates how pronunciation of a name can be influenced by many factors.  Go ahead and read it out loud. 

cy·cla·men

How shall we sound its mystic name
Of Greek descent and Persian fame?
Shall "y" be long and "a" be short,
Or will the "y" and "a" retort?
Shall "y" be lightly rippled o'er,
Or should we emphasize it more?
Alas! The doctors disagree,
For "y's" a doubtful quantity.
 Some people use it now and then,
As if 'twere written "Sickly-men";
But as it comes from kuklos, Greek,
Why not "kick-laymen," so to speak?
 The gardener, with his ready wit,
Upon another mode has hit;
He's terse and brief -- long names dislikes,
And so he renders it as "Sykes."
~~~~~~~~~


Stroll in your garden today and pay attention to the colorful language of spring. 
Appreciate the magical emergence of life and the crescendo of canopies they bring.

Seven-spotted Lady Beetle

Lady Beetle (Coccinella septempunctata) on Flat-Leaf Parsley (Petroselinum crispum)

This seven-spotted lady beetle (ladybug or ladybird beetle) has been spotted in my yard.  Fortunately, this lady is a gardener's friends. Scientifically it is called the Coccinella septempunctata.   Being a predatory insect, the C. septempunctata plays an important role in the biological control of aphids.  Both the adult and the larvae feed voraciously on aphids.  Adults hibernate or overwinter in protected areas.  In the spring when temperatures get warmer, they come out and feed on aphids before they lay eggs.  The females can lay up to 1000 eggs within a three month beginning in spring.  The females are very strategic in their choice of a place to lay their eggs.  They prefer areas with a high insect population such as in gardens, fields and tree canopies. 

The C. septempunctata is commonly identified by the seven black spots on the bright red elitra (singular elytron: are the tough fore wings of beetles and earwigs).  It undergoes a complete metamorphosis.  This means that it has to undergo four stages of change to complete its life cycle:  Egg; Larvae; Pupa; Adult. 

Although most ladybugs are beneficial to plants, some of them are considered pests.  In a future post I will name those bugs and describe why they are not so "lady-like."

An Enemy

Brown Garden Snail  (Cantareus aspersus)

I saw this enemy in the garden today.  Although it has not been named as a serious pest in California, snails, along with their relatives the gray garden slug (Deroceras reticulatum, formerly Agriolimax meticulatus) are annoying pests in home gardens especially during this time of the year when the herbaceous plants are just beginning to emerge from the ground.  It is easy to mechanically control the snails but I prefer to deal with slugs chemically using metaldehyde (2,4,6,8-tetramethy 1,3,5,7 tetraoxycyclo-octane) in late winter and very early spring.  This is the only time I put slug/snail bait in the garden mainly for the purpose of protecting the seedlings.  Later on I hand-pick those that survived.  This way we can enjoy slug-free strawberries.

Important Link: IPM for Snails and Slugs

Did you know?

The brown garden snail is closely related to the Roman Snail (Helix pomiata), the edible snail which is commonly known as Escargot in French cooking.

The Philippines has its own edible aquatic snails known as Kuhol or the Channeled Apple-Snail (Pomacea canaliculata).  They are aquatic; usually found in rice fields as pests.  Recently, it has been found to be good source of feed supplement for livestock and poultry.

Garlic Chives (Kutchay)

Garlic Chives (Allium tuberosum)

As of yesterday, this is how my garlic chives looked like.  They were planted maybe three or four years ago still in the same pot.  They are ready to be divided but I have been delinquent.  Anyway, it looks very good at the moment.  

Garlic chives are different from the common chives (Allium schoenoprasum) by appearance and flavor.  Sometimes they are referred to as Chinese chives or flat chives but in Ilocano (my dialect) they are called Kutchay.   Unlike the chives, kutchay has a strong garlicky flavor which is an important material in my partly-Asian kitchen.  It is good in fried rice, omelets, soups, meats, and noodles.  The leaves as well as the young flowers make a good substitute for leeks, green onions, and sometimes cooked by it self.

Garlic chive is a perennial plant that is easy to grow.  I prefer to start with seedlings purchased local nurseries. Once established, it will continue to spread and comes back year after year.  In fact it is a self-seeding plant thus can become a weed if flowers are not cut off before the seeds get dispersed naturally.  I like to harvest them as needed starting from one end of the row or one side of the pot and moving on.  This way there will always be new leaves to use in the kitchen since regular cutting or harvesting encourages new growth and even spreading.  To harvest, cut the leaves 1-2 inches from the base. 
Annual application of compost early in spring will provide the needed nutrients.  When grown in pots, apply complete or nitrogen fertilizer at a very low rate to replace the nutrients that get washed off during watering. 

Divide and replant when the plants get to crowded (maybe every three to five years). 

Important definition:
Self-seeding plants. (n.) plants with seeds that spread their seeds naturally and without special attention given, the seeds will grow.

Start a kitchen garden...plant herbs.

Mint in the Garden

Peppermint (Mentha pepireta)

Mint must be one of the easiest herbs to grow.  As a perennial plant, mint does not have to be replaced every season.  In fact depending on your location it remains green throughout the year.  I grow mint for adding to drinks, making cucumber sandwiches, yogurt sauce for Moroccan Lamb Kabobs, and garnishing.  

Some Common Mint species:
Peppermint (Mentha piperita) has dark green leaves with a reddish stem and lavender flowers.
Chocolate Mint is a peppermint cultivar which had bronze-green leaves. 
Spearmint (Mentha spicata) has lighter green, pointy leaves and pink flowers.
Apple Mint (Mentha suaveolens) has light green foliage.
Pineapple Mint (Mentha suaveolens 'Variegata’) has green leaves that are banded with white.

It has been my observation that mint undergoes two distinct growth phases in a given year. Understanding the events that happen during these phases helps a gardener grow mint the proper way.

1.  The first phase is the above-ground vegetative growth which happens in early spring (see above picture). The stems will then prepare to flower in the summer.  Frequent cutting will encourage branching and delay flowering. As the plant flowers, the vegetative growth comes to a halt to give way to reproductive development.

2.  After flowering, stolons, which are modified stems, begin to grow laterally underground covering a lot of distance in a very short period of time.  Eventually, these stolons will emerge from the ground and start to grow the next set of stems covering a much larger area.  This is the reason why mint need to be contained.  It is invasive and can become a weed.

Clone your mint
Dig into the soil at the base of your mint plant and look for stolons.   Pull it out and cut into short sections making sure that there are at least three nodes in each section.  I prefer the nodes that already have little buds and roots on them.  Then plant the sections horizontally and cover with soil.  Keep it watered but not too wet.  In no time you will see new green leaves emerge. 

Important definitions:
Propagate  (v.) to clone or grow a new plant from a vegetative part of an existing plant.
Stolon  (n.) a modified stem growing underground.  Distinguishable from the roots by the following: larger in diameter; white color; presence of nodes.

Lost Name

Cymbidium California 'Sun Acres', HCC/AOS
California = Cymbidium Blue Smoke X Cymbidium Alexanderi

Sometimes flower varieties are not always indicated on their labels.  For example, this orchid just came with the label "Cymbidium".  In as much as I am planning to grow some more cymbidium this year, I did some research on the one that I already have.  My closest guess based on flower appearance would be Cymbidium California 'Sun Acres'.   So until proven wrong, I will assume that this is the variety I have.


This orchid displays nice tall spikes of vibrant yellow-green flowers with lips that are ringed with burgundy markings.  It is blooming now (February).

Herbs in My Garden

Sage

Herbs are plants that are used to add flavor, color, or spice to food. They are easy to grow and require a relatively small space to grow.   While some herbs are grown for their medicinal value, mine are grown them for their culinary value.  They come in different colors, shapes, and height that they can be ornamental at the same time.  In my garden, I like to plant herbs that I use in my cooking.

Herbs Found in My Garden:
Sweet Basil (Ocimum basilicum)
Thai Basil (Ocimum basilicum var. thyrsiflora)
Chives (Allium schoenoprasum)
Peppermint (Mentha piperata)
Rosemary (Rosmarinus officinalis)
Thyme (Thymus vulgaris)
Cilantro (Coriandrum sativum)
Flat Parsley (Petroselinum crispum)
Oregano (Origanum vulgare)
Sage (Salvia officinalis)

Rosemary, sage and thyme are perennials.  Perennial plants come back year after year. They need to be trimmed from time to time to control their shape or to encourage more branching.

Annual herbs like basil and cilantro complete their life cycle within one season or one year after which replanting is necessary.  Sometimes their life cycle can be delayed by cutting removing the flowers.  This works weel with basil.

Mint is also a perennial plant but here is a word of caution: Mint is invasive and can become a weed.  To prevent it from becoming a problem contain its growth by planting it in a pot or a planter box.

Chives has its own special feature.  It is a perennial and self seeding plant.  Not only does it come back year after year, it also spreads its own seeds.  Unless the flowers are cut off before they mature, chives can also become a weed.


Rosemary


Yesterday I bought some cilantro and parsley seedlings.  There are three seedlings in a pot so what I normally do is to spread the seedlings apart into a bigger pot to allow more room for each plant to grow.   I like to plant them in pots so thatI can move them around.  When it is too hot I move them to a place where they get more shade.  As the cooler months approach I will be moving them so they get more sunlight to compensate for the shorter days.  The California temperatures will gradually decrease and by the time temperatures become limiting to plant growth it will be December.
