And What Do You Do?

Kevin Cohn

            When we meet someone new and try to get past the awkward dance of what to say, we look for neutral ground.  After a few minutes, it’s usually safe to ask: “And what do you do?”

            When it’s my turn, I’ve always said: “I’m in the greenhouse business, I grow plants for sale.”  The first part has always been misleading because it sounds like I sell greenhouses, so I added the plants.  It’s matter-of-fact and not that interesting.
            I ran into a TED talk that presented that we should start our answer to—what do you do, with “I help….”

            “I help Garden Centers find interesting ‘Mini’ plants.”

            This usually leads to follow up questions like: “How do you do that?” or ‘What kind of plants?”

            If this meeting is with the Garden Center houseplant buyer, I can go deeper.

            I have a collection of foliage houseplants that are not commonly available.  They are selected to be suitable for Miniature Gardens and Terrariums.

            But we know that 90% of ‘Mini’ plants sold are not used in a Miniature Garden or Terrarium.  They are grown as a windowsill plant or moved into a bigger pot as a houseplant ---often put into a decorative container.

            And what do you do?

Let's make a better Lipstick Plant

The Classic Lipstick Plant

     The classic Lipstick Plant that everybody has heard of with lipstick tube red flowers could be better.

         The goal of purposeful plant breeding is to create something new and hopefully better for the World to enjoy.

          I’ve been asked how today’s plants compare with 50-year old varieties.  That’s easy --- the plants are better.  Professional plant breeders have taken road-side weeds and selected them into flowering wonders.

       Amateur plant breeders have created exceptional improvements in the Plant World, also.  These dedicated hobbyists are amateur, but only in that they are not paid.

            All of the Aeschynanthus hybrids have been made by amateurs.

         I have a project for all to consider.  Flowering of A. lobbianus is unreliable.  What if it could be converted to a day-length sensitive plant like A. ‘Big Apple’?

         At least one of the parents of ‘Big Apple’ (micranthus X humilis) must be a long day plant.  We cross these species with lobbianus and select for large tubular red flowers and the seedling that is long-day.

            Is this feasible?  I don’t know yet.

            Perhaps others can speculate?

'Big Apple' is a major new commercial crop

           Aeschynanthus ‘Big Apple’ has become an overnight success.  They are available in every garden center, every supermarket plant department and every big box store as plant of the week.

            I’ve missed April Fool’s Day, but it could happen.

            With my discovery that this unknown flowering houseplant is a long-day to flower plant, it can be programmed to flower every week of the year – guaranteed.            

Why won’t it happen?  Because nobody will do it.

There are fewer pot plant growers than there used to be and thus fewer specialist liner producers promoting flowering plants like ‘Big Apple’.

There are a few things to test, like post-harvest reliability --- will the flowers hang on in shipping?

            It will be fun to see if I can flower 200 4” pots of this interesting, unknown hybrid, ‘Big Apple’.

Why does A. 'Big Apple' Flower?

Why does A. ‘Big Apple’ flower?

Aeschynanthus ‘Big Apple’ is not commonly grown in commercial horticulture.

Strike that --- it’s never seen.

The hybrid ( micranthus x humilis) is very colorful when in flower with red tubular flowers in clusters on an upright plant.  Aeschynanthus is a Genus with many species and hybrids of all sizes and shapes. And we know that flowering is variety specific.

            The one that everyone knows as the Lipstick plant is still sought after with its bright red flowers.

            ‘Big Apple’s flowers are much smaller, but a cluster of them is impressive.

            What makes ‘Big Apple’ flower?

            From our production of ‘Big apple’, I now know the trigger for bud-set and flowering.

            It is a long-day plant.

            We see small buds on every shoot now in April.  So, they were probably starting in March when the day length started to get longer.  We should see open flowers by May and continuous flowering though the Summer.

A day-length sensitive plant has its benefits to a commercial grower.  Vegetative growth and flowering can be programmed --- flowering is not random, it’s predictable.

So here it is.  Propagate in the Fall, pinch and build plant in the Winter.  Get buds in April, flower in May/June----- Guaranteed. 

So, what’s a hobby grower to do?  If it’s a windowsill houseplant, don’t expect flowers in the Winter.  Wait till Spring and Summer.

If you grow under florescent lights, understand that you can manipulate flowering with the number of hours of lights-on.  8-10 hours for growth, then 14-16 hours for setting bud.  I would expect once the buds are set they will open no matter what the day-length is.

A.    ‘Big Apple’ ---- A long-day plant.
