Did you ever notice that there are three yak Jean Marie hybrids, all done by different hybridizers using three different yakushimanums that are polyploids, probably triploids? Hank Shannon’s ‘Solidarity’, Phil Waldman’s ‘Anita Gehnrich’ and Ray Kruise’s unregistered hybrid that I call ‘Ray’s yak Jean Marie’. All these hybrids are very similar: vigorous growers, hardy with rather large pink flowers. It is not easy to tell them apart.  Now I do not know how many seedlings of each cross were grown but I can’t imagine it was an enormous number.  And each hybridizer got a triploid from his batch of seedlings!  It is so unusual to get triploids and here each got at least one. So in 2012 I decided to make the cross again using three different yaks that I have:  a very dwarf form, the FCC form and a larger growing form.  Neither of these yaks are hybrids as all were grown from seed collected on Yaku Island.

I put Jean Marie pollen on the three yaks and also did the reverse cross: yak pollen onto Jean Marie.  Six crosses.  Only two of the crosses produced seed and not much at that;  yak FCC x Jean Marie and  Jean Marie x yak FCC.  I have six seedlings of each cross as of  March, 2015.

Of the six yak FCC x Jean Marie one I almost guarantee in a polyploid and maybe two more.  Of the Jean Marie x yak FCC one might be a polyploid. Now I know the plants are very young and it is going to be several years before they bloom but now only two years old there is a remarkable difference in their rate of growth.

Now isn’t that interesting.  Is that serendipity or is there something going on between the two plants?  This year I plan to remake the crosses and see if I can get more seed.  Written 3/21/15

 

 

 

When I first saw the flower on Harold Amateis and was told of its background I couldn’t believe it. How could that strong a red come from maximum in the first generation.  Maximum had a terrible reputation here on Long Island as a parent.  Clem Bowers made many, many crosses using in in the 1930’s & 40’s and didn’t get anything of value.  Of course he wasn’t using strig, mainly the ironclades and some of the English giants.  Paul Vossburg wouldn’t have anything to do with a maximum hybrid.

I was always leery of the cross and wondered if Edmund Amateis could have mixed up the seed.  But now I see the picture of max x Leo and lo and behold another red truss.  Is there something about maximum that transmits the pollen flower color to the seedlings?  If that is the case, has anyone tried crossing it with a strong yellow?  What about crossing it with Jean Marie?

There were several problems with max crosses:  erratic bloom (as we know from Harold Amateis), bad plant habit (very open growing) and does poorly with full exposure.  I have a max x yak that I got from Sid Burns that is a good looking plant.  It blooms in very late June with large white trusses, is slightly indumented, holds its leaves 3 years and never has any winter damage (that is not saying mulch as I am in zone 7b).  It is quite a vigorous plant.

Since most rhododendrons are sold as containerized plants, it is imperative that the purchaser knows how to plant it in his/her garden.  Hank Shannon and Ron Rabideau from Rare Find Nurseries produced a wonderful video showing how to do it.  EVERYONE SHOULD SEE THIS VIDEO.  The URL for it is: https://www.youtube.com/watch?v=02KxkPQdDd0

Rooting Rhododendron and Deciduous Azalea Cuttings

 

Requirements:

Moisture – The cuttings cannot be allowed to dry out.

Capable cuttings – Cuttings should be taken in September or October and from the lower branches on the shady side of the plant. Avoid thick, fat stems, rather chose thin stems.

Allow roots to emerge – Root initials are found in the cambium layer, a thin layer of cells directly under the bark and on top of the hard wood inner stem.  Remove a one inch sliver of bark at opposite sides of the base of the cutting to expose the cambium layer. This is called a wound.

Hormone – Use the strongest hormone you can buy.  I use a 2% IBA powdered hormone. Just dip the wounded base of the cutting in the hormone and tap to remove extra hormone. Many people use Woods Rooting Compound made by Earth Science Products Corp.  It is a liquid and is 1% IBA.

Rooting Mix – A mixture of peat with sand, pearlite or vermiculate.  50 – 50. Mix should be moist but not sodden.

Procedure:

Take cuttings of current year’s growth, cutting just above the leaves from last year. Take cuttings in the early morning the day after rain or irrigating the plant.  Immediately place cuttings in plastic bag and close bag to reduce water loss.

Wound cuttings by removing a one inch sliver of bark on both sides of the lower end of the cutting. I cut about 1/3 of leaves off to be able to get more cuttings in the bed. Do not let the leaves overlap a neighboring cutting as the covered leaf will abort.      Dip in hormone and stick into rooting mix by first making a hole with a pencil or finger.  Do not compress the mix around the cuttings, the roots want an airy mix in which to grow but gently fill the space between the cutting and the mix. The mix can be in any container.  The container, mix and cuttings should be placed in a sealed plastic bag and placed in a very light area but no direct sunlight as sunlight will heat up the bag.  Water is not necessary as the sealed plastic bag will prevent water loss.  I root mine under 18 hour fluorescent lights.

Bed covered with plastic. The plastic is translucent not white as it appears in picture.  Lights are 15" above the cuttings.

Bed covered with plastic. The plastic is translucent (called ‘clear plastic’) not white as it appears in picture. Lights are 15″ above the cuttings.

The frame is 8′ x 4′ (the size of a standard piece of plywood) with 6″ high sides.  There are 4, 2 bulb light flixtures over the frame which are on 18 hours a day. In May open the bag for a few days to acclimate the plants to the atmosphere. In June plant the little plants in a protected spot in the garden.  Fertilize with water soluble fertilizer several times over the summer, stopping on August first.  Do not let the little plants dry out.

Deciduous Azaleas: Rooting deciduous azaleas is similar to rooting evergreen rhododendrons  in that the mix, the hormone and the lights are the same.  The main difference is that the cuttings are taken July 4th in my garden. (I live on Long Island, a suburb of New York City.)  The cuttings are very soft, but that is OK.  A wound is not necessary.  The cuttings root quite rapidly and by October 1st are ready to be removed from the propagation bench (to make room for rhododendrons!).  THE ROOTED CUTTINGS MUST HAVE A FLUSH OF GROWTH BEFORE THEY GO DORMONT AND DROP THEIR LEAVES.  If they don’t have a flush of growth they will not leaf out next spring.  This is accomplished by putting the rooted cuttings under 24 hour lights.  After the new growth is mature put them in a cool place with natural light and they will go dormant.  Do not let them freeze.  Next spring plant them out in a protected spot and away you go.

Commercially mature plants are lifted in the late fall or early winter after they have dropped their leaves and have been dormant for a couple of months and placed in a warm greenhouse.  This is usually December.  By February they have done their spring thing: bloomed and produced new growth.  Soft wood cuttings are taken and rooted.  In May or June they are planted out.  Over the summer they will have a flush of growth and are thus ready for the winter dormancy and will leaf out next spring. They should be placed in a cold frame for the first winter.

I do not pinch SEEDLINGS as I want to see how the plant develops naturally on its own.  The plant growth characteristics are just as important as the flower and hardiness.  Almost all casual home gardeners are not going to pinch a rhododendron to try to make it into a dense, bushy plant.  To take a seedling and pinch it to make it into something it wasn’t meant to be is fooling the hybridizer and anyone who propagates the plant.

This brings to mind “feau plants”.  I can remember giving a talk to a chapter and before my talk the plant chairman showed off some of the plants the chapter was going to sell at the upcoming plant sale. He had plants of ‘Scintillation’ in 15” pots that were prime examples of ‘plants on steroids’. They were obviously plants grown using forcing techniques to develop a four year old looking plant in a year and a half.  They had leaves to the ground and a flower bud on each terminal.  Spectacular.  Dense and bushy they looked like a 10 year old yakushimanum without an indumentum.

The casual gardener who purchased one of these was going to have a fabulous plant when it bloomed, but it was all downhill from there.  As soon as it got into a normal growth cycle many of the leaves would drop.  Even though it was dense and bushy when purchased, it was destined to grow into an enormous open growing plant that would overwhelm most small gardens after 15 or so years.  No one told the purchaser of the need to yearly give the plant a “Delp Pinch” to keep it full and bushy and anyway he probably would not have done it as casual gardeners don’t want the burden of constant care for plants.  “Plant it and forget it” is their idea of horticulture.

But you know it probably wouldn’t live for more than 3 years in their garden because of the problem of the difficulty of successfully planting a containerized plant and have it survive.  Several years ago Hank and Ron produced a video that was fantastic.  It showed precisely how to do it.  The astounding feature of the video was the degree to which Ron cut up the root ball.  Here is the http for the video: http://www.youtube.com/watch?v=02KxkPQdDd0&NR=1  Without seeing this video, how many casual gardeners do you think would tear apart the root ball as shown in the video?

So here we are; providing overgrown plants to unsuspecting gardeners who will not be successful with them unless they are explicitly told to tear apart the root ball.  How many times have you been asked, “Why did my rhododendron die?” It is the constant question from casual gardeners to me.  How long do you think casual gardeners are going to purchase rhododendrons to replace the ones that they were previously unsuccessful with?

 

 

 

These are pictures of my “Especially Noteworthy Plants” These are the best of all my numbered plants. It changes from year to year.  Many of these will be available as small plants at the Northeast regional meeting in the fall of 2015.

I planted my seed in the middle of October this year. I usually plant it the end of November but I wanted to see what happens when I plant early. I made 44 crosses and many didn’t produce seed. I also collect open pollenated seed from a few rhododendrons that almost never set seed. I also planted some seed given to me. Just because I said “yes” to whether I have seed doesn’t mean there was seed. Very frequently I will crush seed pods even when I don’t think there is seed and plant the whole mess to see if there might be 1 or 2 seeds. I would guess that half of the crosses didn’t take. I will indicate the number of seedlings when I transplant them. (“JM” is Jean Marie). 12/21/13.

12/29/13:  I have updated the approximate number of seedlings of each cross below.  Obviously the seedlings are very small and I won’t transplant them to flats for at least another month. I plant my seed in old fashion clay pots using screened oak leaf mold that I scrape off the ground in oak woods. I half fill the pot first with wood chips and then put the mix in the pot to the very top and mound up the mix so the center of the mix in the pot is 1/4 inch above the pot lip. I immerse the filled pots in water up to the lip of the pot  for 24 – 48 hours to completely soak the medium.  I sprinkle the seed on the medium and place the pot with the seed in a plastic bag, being sure there is 1/2 inch of water in the bottom of the bag.  The clay pot acts as a wick and draws the water up to the top of the pot to prevent the seed and the mix on top from drying out. I then seal the bag with a twist tie and place it under 24 hour flourescent lights. The lights are about 8 inches above the top of the pot.
