Niagara Region. Plants for Members - May 2007 1
In 2005 a number of cuttings were taken from plants grown by local members. These plants are proven performers.
The cuttings have been rooted and are now groing on at Van Veen gardens.
In May, 2006 the cuttings will arrive in Niagara as husky young plants that will be potted up by
Marian Little and Rolf Schoen and will be grown on for the rest of the summer in one gallon containers. This is a repeat of the very successful event that occured in May 2005. The plants offered then were well received.
These Rhododendrons will be offered to our members at the May, 2007 meeting for a very nominal price.
None of these plants are commercially available in this area at this time and should be a welcome addition to members gardens. Information about each hybrid is listed below2 |

Please click on the image to open a larger version in a new browser window. A Delp lepidote (Achiever x polycladum Scintillans Group) that Rolf Schoen has grown in full sun in his yard since the early nineties. Each spring it is covered with pink-lavender flowers on a well-branched plant. Hardy to -29°C. Midseason bloom. Leaves broadly acute apex, cuneate base, 1 1/2" long. Small pink flowers that open later in the season with a generous covering Of dark green foliage. A Hachman cross (degronianum ssp yakushimanum 'Koichiro Wada' x Spitfire) , predominantly red flowers with slightly indumented leaves. Height to 4 feet in 10 years. Claimed to be hardy to -21°C. Midseason bloom. Foliage is elliptic, dark green with light indumentum on the underside. Plant habit is round and compact. A Dexter hybrid (unknown parentage) that can grow to 7 feet in 20 years. R ose-red flowers up to 18 per truss. Rated to -21°C. Leaves narrowly elliptic to elliptic, broadly acute apex, rounded base, 4 1/2" long, moderate olive-green, retained 3 years. Broad, dense habit. Prefers a shady location. A number of them have done well in Niagara. In Yarmoshuk's garden this plant grows on the north side in dense shade and provides prolific bloom every two years.
Whatever the true name of this plant, its characteristics warrant a very special place in your garden. 'Mood Indigo' was crossbred by the late Lester Brandt of Tacoma, Washington, whose best known creation was 'Kubla Khan.' To develop 'Mood Indigo,' he started with the Chinese Rhododendron augustinii ssp augustinii & pollinated it with unrecorded species or cultivar. The resulting 'Mood Indigo' was never registered3.
In the late 1970's, Al. Smith entered a beautiful blue lepidote.in then annual Niagara Rhododendron flower show. Jack Looye asked him what it was, Al replied "Ilam Violet". It caused quite a stir; everyone wanted one. Later that summer Al Smith told Jack Looye and Rolf Schoen that Clay in BC had some big plants of Ilam Violet for sale. Of course several members of the local society got one.
It seems hardy and blooms every spring. The only time it got damaged, together with Blue Ridge from the Haage's, was after the 93-94 winter when temperatures dropped to -20 F and Rolf lost part of both plants. Jack Looye talked to different people about this including D. Leach, who said the plant could be Rhododendron Mood Indigo that had been surprisingly hardy for him. The conclusion is that the plant shown in the four photos above probably came from Al Smith and is not Ilam Violet but probably is Mood Indigo. Jack Looye, Rolf Schoen and Nick Yarmoshuk believe it is much better and hardier than Ilam Violet. This information is provided here to keep the record straight. Otherwise confusion will exist about Ilam Violet and its rated hardiness.
These trusses come from a grex of seedlings from ARS seedlot # 753 germinated in 1982 and grown by Nick Yarmoshuk.
This is a very slow growing plant, providing a compact mound about 3 feet tall and as wide after 20 years. When it blooms after a mild winter, it is a lovely sight to behold. It is a beautifully formed plant and does very well in full sun as a foliage plant, although there is evidence of sun scald. Some noonday shade would probably be very much appreciated. Nick Yarmoshuk named this plant on the spur of the moment at a Niagara Truss Show. He just wanted folks to know the plant came from Cordy in Pennsylvania in 1982 when Jack Looye, Lyall Crober, Al Smith, Brian Schram and Nick Yarmoshuk went to the ARS meetings in Washington DC. On the return trip they picked up a lot of yearling plants at Earl Cordy's including this smirnowii x yakushimanum cross.
The leaves have heavy indumentum. The first potograph above reveals the pink flush of a newly opened truss. Cordy's Pride is shown here with Azalea Luteum.
These trusses come from a grex of seedlings from an 1982 ARS seedlot for which the seedlot number had been lost. The seeds were germinated in 1982 and grown by Nick Yarmoshuk.
Vernus parentage is catawbiense hybrid x Cunningham's White . This elepidote appears to be very hardy; it blooms in midseason. Both plants, for the first half of their lives, were abused in that they were grown in crowded conditions which forced the early stems upwards and did not allow the plants to develop side branches. The two accompanying photographs to the immediate left (above and below) show the effects of liberating the plant to allow side branches to develop. The second plant to the immediate left shows better form that the one above. Both plants are approximately the same height, approximately 4 feet each. They are approxmately 3 feet wide. Despite the dissimilarities in the forms of the plants there appears to be little to differentiate the trusses and florets produced by each.
This truss is from a plant in Rolf Schoen's garden.A Cowles hybrid from the Heritage Plantation with cream flowers and shiny dark foliage. About 1meter high after 15 years.
Salley and Greeri describe this hybrid as follows: '5.5 ft high x 8 ft after 25 years. Flowers light greenish yellow in flat truss of 12. Growth habit spreading very dense'.i
A Dietrich Hobbie hybrid that, despite its scyphocalyx breeding,does well on the northside of the house. A slightly open plant with orange-red flowers.
2Description of each named variety is an amalgum of information contributed by Rolf Schoen, Nick Yarmoshuk and the Plant Index of the American Rhododendron Society web site http://www.rhododendron.org/search_intro.htm and edited by N.Yarmoshuk. Photographs of Ilam Violet, Janet Blair x Melrose Pink and Cordy's Pride are those of plants growing in Yarmoshuk's garden made abailable by N.Yarmoshuk. Photographs of Faisa, Morgenrot, Gigi and Spellbinder were copied from the archives of the American Rhododendron Society website.
