If you want to buy a rose anytime this year, January’s the time to do it. They have just arrived in the nurseries and are cheap, transplant well right now, and the selection is fantastic. (Next month they’ll be even cheaper, of course, but do you want to risk your favorite being gone?)
Here’s how to select a strong, disease-resistant rose:
Choose Non-Grafted or Own-Root Roses –
This isn’t a necessity, but it helps – most roses are grafted onto a more vigorous set of roots, from a different variety of rose. The problem with this is that if you don’t keep your wits about you, that vigorous rootstock could rise up and overtake the delicate beauty you chose.
I usually see this in gardens where the sweet caretaker grew too old to be able to keep up, and after a few years of neglect and weediness, a lot of the roses reverted to the rootstock variety, which rarely blooms and isn’t worth its thorns. I like to think of my gardens as gifts I give to the future, so choosing roses on their own roots is a bit of insurance.
They’ll usually note it on the package if the rose is on its own roots; otherwise, assume it’s grafted. You can see for yourself, too – look for a knotty-looking bit at the base of the plant where they attached the variety you actually want onto a different root system. Plants grown on their own roots won’t have that knot. (I’d give you a list of own-root roses, but it varies depending on who grows them.)
Look for Low Petal Count -
As a rule of thumb for the Maritime Pacific Northwest, go for the lowest petal count you can find – that is, look on the packaging of your bare-root rose to see how many petals each flower has (it’s usually listed). The fewer the petals, the less moisture the flowers will hold and the longer each bloom will last in our climate.
The ideal easy-care rose for our climate has less than 25 petals. If it has many more than that (40’s about the limit here), it will probably disappoint you by starting out with huge, gorgeous buds that turn a manky brown just as they should be opening into fragrant rosy perfection.
That’s just a general rule, however: If you are a fan of the ruffles, there are some David Austin roses, bred in a similar climate in England, that do really well here. A client who visited England came back with a passion for them and I’ve been shocked at how well they do – at the first sight of all those frills I cringed, imagining the brown mess of disappointment they’d bring – but they’ve been ace – blooming so mightily that I am often gifted a bouquet in summer! Check out this article for Austin recommendations.
They Should Tout Their Disease-Resistance -
If a rose is willing to stick it out in a garden without a whole lot of spraying, chances are that’s an attribute they’re going to be talking about. Assume the worst of your roses, and veer away from all the fancypants new varieties unless they are specifically saying how they resist disease – seeing as even the resistant ones still have issues.
A few of my favorite, easy care roses?
‘Iceberg’, the best white rose for our climate. It’s often grown on its own roots, does well with minimal spraying, and has a really long season of crisp white roses. There are also Pink Icebergs, Climbing Icebergs, and the awesome ‘Burgundy Iceberg’ (below) which all have the same good qualities as the original.
‘Gourmet Popcorn’ is a fun miniature rose with a flurry of tiny white floofy flowers with yellow centers. They’ve proven disease resistant here on the foggy coast in both landscapes and containers. The stems aren’t long enough for cutting, but hey – they are adorable, bloom profusely all season, and I have never had to treat mine for pest problems.
‘Bonica’ is a sweet shell-pink bloomer with lovely dark green foliage. I love how the roses aren’t quite the traditional shape –they are a little looser and less formal. Good cut flowers and a pretty 5’ tall habit.
‘Sally Holmes’ is an old-fashioned pinky-white shrub rose which is super disease-resistant! In all these years, I have never once seen it with even the smallest bit of black spot. It grows to a strong 6’ tall and wide shrub, and if it weren’t for all of the deadheading of those big bloom clusters (this gal blooms almost constantly all summer even into November), I’d consider it a low-maintenance plant. It’s usually not grafted.
‘Sally’ starts off white but quickly turns a pretty pale pink as each flower ages. Again, not much of a cut flower – the petals go everywhere – but what a stunner for the garden!
‘Zephirine Drouhin’ is a pretty raspberry-pink thornless climber which tolerates tough conditions – lousy soil, a bit too much shade… It’s the only rose I like to plant on a heavily used arbor, because – hey, have you ever caught your face on a thorny branch while walking by? I have, and that’s why I like the non-thorny ‘Zephirine’! Her fragrance is fresh and fruity – not too heavy.
The Flower Carpet line from Monrovia is also excellent – disease-resistant, does great in containers, and comes in a variety of colors. I can’t wait to try out the new Amber one (click through to Monrovia to see them all.)
Hope this gets you all inspired to check out the bare-root selection at your local nursery. If you are ordering online, may I recommend Regan Nursery? They have a lot of great varieties and obviously care deeply about roses and the people who love them.
