Plant of the Century
As part of the 100th anniversary of the Chelsea Flower Show in England this year, the Royal Horticulture Society nominated 10 plants to vie for Plant of the Century, one introduction for each decade.
Geranium ‘Rozanne’, a perennial cranesbill introduced by Blooms of Bressingham won the contest.
Bressingham Gardens in Norfolkshire in England is one of the world’s premiere nurseries. Alan and Adrian Bloom, father and son, have introduced many wonderful plants over the past half century. Their nursery is a must see in England. ‘Rozanne’ is a long-blooming, blue-flowered perennial geranium that is popular in the United States. ‘Rozanne’ is named for Rozanne Waterer, the gardener in Kilve, Somerset, England who discovered it in her garden in 1989 and asked the Blooms to introduce it. First shown at Chelsea in 2000, it was introduced to the United States in 2001 and was named perennial plant of the year by the Perennial Plant Association in 2008.
It is touted to grow well from Canada to California in most any soil. I just wish it did better in my garden, although I do like it. Perhaps it needs afternoon shade. A friend in South Amherst reported that it didn’t thrive in her garden either. The mounding, sprawling plant with violet-blue flowers usually blooms all summer, which wasn’t true of the old ‘Johnson’s Blue’ or even ‘Brookside’ both of which I have grown in the past.
The other nominees were: varieties of saxifrage and pieris, lupine Russell Hybrids, Rhododendron yakoshimanum, ‘Iceberg’ rose, Cornus ‘Eddie’s White Wonder’ from Canada, a perennial wallflower, popular ‘Palace Purple’ heuchera, and a houseplant: Streptocarpus ‘Harlequin Blue’. I think I would have voted for ‘Rozanne’ myself, even though it probably does better in England.

SALVIA REPORT: In the spring I wrote that I wanted to buy several annual salvias plus the new Coreopsis ‘Mercury Rising’. Well, the coreopsis is planted in my front garden and should bloom soon. After reading my article, Peter Flynn at Bay State Perennial told me he prefers Coreopsis ‘Red Satin’ so I went out to Whately last week and bought one to try. ‘Mercury Rising’ is a hybrid of C. lanceolata with lance-shaped tapered leaves. ‘Red Satin’ is a C. verticillata with thin, fine leaves. I didn’t dare plant that next to my species C. verticillata that is almost invasive for fear they would entangle themselves. So ‘Red Satin’ is on the other side of the front walkway across from ‘Mercury Rising’. I’ll give you a full report later in the summer.
Meanwhile, I couldn’t find most of the salvias on my wish list locally, so I had almost given up when I was surprised to find Salvia ‘Madeline’ at Bay State. It turns out to be a perennial, obviously related to my favorite S. transylvanica. At least the leaves and branch structure are similar. ‘Madeline’ is supposedly hardy to Zone 4 (certainly true of transylvanica) and has blue and white bi-colored flowers. I bought it in full bloom and just hope it continues to flower for a few weeks. According to the label, if you cut it back (like S. transylvanica) it will rebloom.
So far, my only annual salvias are S. farinacea for my blue pots but I almost got a S. sinaloensis at Andrew’s Greenhouse on Sunday although I couldn’t think where to use it well. I’ll probably go back and get it and another annual later.
S. ‘Rhapsody in Blue’, the perennial about which I learned from Nick Dines in Williamsburg and was a gift from master gardeners on our Maine trip, is blooming splendidly in my white-yellow-blue garden. I like it so much better than ‘Caradonna’ for which I “settled” last year when I couldn’t find ‘Rhapsody in Blue’. The ‘Caradonna’ has thin flower spikes that are really purple while ‘Rhapsody in Blue’ is almost true blue with much thicker flower stalks.
