Went over to Hamilton yesterday to spend a day at the Rogers Rose Garden enjoying the annual Pacific Rose Bowl Festival and the National Rose Show – and although the enjoyment factor remained high, the weather was decidedly dismal with, at times, lashing rain and strong winds. And when it wasn’t lashing rain, it was still raining!
So when 2pm rolled round and rose breeder Rob Somerfield and national Rose Society publicist Hayden Foulds turned up to give a guided talk, the Vege Grower and I were their audience of two. The guys were game and so were we, the little matter of brollies being blown inside out a mere trifle.
We eventually stopped in front of Eye of the Tiger, a small bush, albeit with vigorous, thorny new growth, that the Vege Grower and I had remarked on earlier, drawn by the colours and look of the flowers. And here we heard an unusual tale.
One of the parents of Eye of the Tiger is Rosa persica (or Rosa berberifolia) which for a while was known as Hulthemia persica and not considered to be a rose! The plant is native to Iran, Afghanistan, central Asia and through to Siberia. It has a single, open rose-like flower with prominent stamens, is thorny but doesn’t have a rose-like leaf and as you can see from the photo below the buds are something else again. It has a suckering habit.
But, rose breeders being what they are, some have been attempting to use R. persica, partly because of its hardiness – R. persica takes everything from drought to freezing in its natural habitat – but the plant is difficult to work with and has resisted many attempts to hybridise it. Breeders want to lose the single flowering, the thorniness, the suckering and the sterility, but want to keep that “eye” splash of colour at the centre of the flower.
This 1977 article by renowned English rose breeder Jack Harkness (who died in 1994) outlines some of the history of attempts to use the plant (it’s a little technical). Harkness Roses released three hybrids using R. persica in 1985 (Tigris, Euphrates and Nigel Hawthorne) and a later one, Xerxes, but none of them were repeat bloomers.
Bright as a Button, a rose by Chris Warner of Shropshire, England – who has also bred Eye of the Tiger (breeding name Chewbullseye) – also uses R. persica and is an award-winning rose in New Zealand, while his For Your Eyes Only (only 30 years in the making!) has won the 2015 Rose of the Year title at the Hampton Court Flower Show.
