John Franklin

The most prolific bloomer of the Ag-Canada roses, according to a 1992 Horticulture article by Ian Ogilvie and John Arnold, is the medium-red shrub rose 'John Franklin'.  Unfortunately, although Ogilvie and Arnold listed 'John  Franklin' as having medium resistance to blackspot, John Franklin is one of the worst of the Canadians for disease resistance in my Kansas garden.  I might see the advertised 14 weeks of bloom on him, but if I don't watch and spray this bush, 10 weeks of his bloom will be carried above bare-stems.
'John Franklin' is otherwise a really nice shrub rose, with clusters of semi-double flowers appearing in rapid succession.  This pink-rose-red tone is not my favorite color among roses, but if you like the color, you'll see a lot of it on this bush.  Bred by Dr. Felicitas Svejda in 1970, and introduced  by Ag Canada in 1979,  'John Franklin' is a well-mannered shrub rose of the Explorer Series that has matured at about 3 feet tall and 3 feet wide in my garden, a great big red ball without many thorns.  'John Franklin' is very hardy in northern gardens, but alongside the lack of disease resistance I must also note that I find little fragrance present in the blooms.  The seed parent is believed to be 'Lilli Marleen' and the pollen parent 'Red Pinocchio' X ('Joanna Hill' x Rosa spinosissima).
   
'John Franklin' is likely a great example of a rose whose blackspot resistance may vary depending on the exact endemic strain of the fungus in a garden and on regional environmental factors.  Ogilvie and Arnold listed 'John Franklin' alongside 'Champlain' as having medium resistance to blackspot, but I find 'Champlain' to be a far more superior rose in blackspot resistance, bloom time, color, and overall garden impact.  Helpmefind.com states that 'John Franklin' is "very disease resistant," although one member of that site comments that he is prone to rust in California.  The red hue of this rose also seems to vary by location, with some pictures on the web appearing almost orange, and others near-crimson.

'John Franklin's explorer namesake was a Rear-Admiral of the British Navy who perished in 1846, along with his starving, lead-poisoned, cannabilistic crew and his icebound ships, during an attempt to chart the Northwest Passage.  In the case of 'John Franklin', the rose, I suspect that over the years horticulture may well imitate history and we won't see much of this rose except in those very cold Zone 3 and below areas, where anything that blooms is still welcome and blackspot doesn't grow well enough to bother roses.  And, of course, as global-warming continues, this rose is going to have less and less land to grow on, since it won't grow in the increasingly open seawater above the Arctic Circle and the Zones are moving ever-farther north.  Does it even snow in Canada anymore?

Oh Canada!

I'm not a hockey fan and I don't remember recalling that "eh?" was on my high school English teacher's list of good grammer phrases, but I do thank God for the poor frostbitten Canadian gardener who initiated the AgCanada program for breeding hardy roses.


'Hope for Humanity'
Over the past couple of decades, the Canadians have introduced approximately 37 rose cultivars bred to survive the harsh winters alongside our Northern cousins. These roses were released in two named series. The Parkland Series roses, which tend to be small shrubs with modern coloring characteristics, were bred in Manitoba at the Morden experimental station. The Explorer Series, bred in Ottawa, Ontario and trialed there and at the l'Assomption, Quebec locations, were named after famous Canadian explorers and they tend to be larger shrubs and climbers. I'm currently growing 19 Canadian roses here in the Kansas Flint Hills. Look on the accompanying pictures of dark red 'Hope for Humanity', on the overwhelming first display of bright red 'Champlain', and on the delicate yellow-pink glow that is the beauty of 'Morden Sunrise'. Why wouldn't anyone want to grow these babies?

'Morden Sunrise'
Imagine, you zone 2, 3, 4, or 5 gardeners, not having to use any winter protection to ensure the survival of your roses. Imagine climbing roses in Zone 4 or below who can reach the top of an arbor and whose long canes survive to bloom in the spring. And imagine roses that have been bred to be blackspot resistent as well, because that was part of the goal of the Ag Canada roses program. They even produced a chart listing the number of weeks that each cultivar bloomed during the summer. 'Champlain' and 'John Franklin' are absolute continuous bloomers!

Over time, I'll focus a blog or two on more of these striking introductions. Unfortunately these government-sponsored breeding programs have been discontinued and won't be releasing new roses, but in the meantime, 'Hope for Humanity' can give us all a little hope that other varieties from other breeding programs will be coming down the pike to brighten our gardens.
