Our vote for the best plant of the century

Plant experts at Thompson & Morgan have been reviewing the list of plants short-listed for the best plant of the century by the Royal Horticultural Society, and we thought you might like to hear our number one vote….

Buy Geranium Rozanne

Buy Geranium ‘Rozanne’ from Thompson & Morgan

Paul Hansord, managing director has worked with the company for 25 years and knows a good plant when he sees one. Not satisfied with reports, Paul always tries to make sure that he tests the best of the best new plants in his own garden before they launch, so he really gets to see the plants up close and personal.

Geranium ‘Rozanne’ has always performed extremely well in my garden, outperforming all other hardy geranium varieties. The large, sky-blue flowers with an attractive eye will flower from late May until late in the autumn, quite unique for a hardy geranium. ‘Rozanne’ has never failed to burst into life each spring, even this year after the cold, miserable, wet winter. I recommend this excellent geranium for Plant of the Centenary due to its colourful displays for months on end, its pest and disease resistance and extreme ease of growth. Over the years, I have grown many of the plants shortlisted on the RHS Plant of the Centenary, but not one of them came close to ‘Rozanne’ for garden performance. It represents an amazing advance in hardy geranium breeding, so vote now and plant some into your garden as soon as you can! You won’t be disappointed, I guarantee it.”

Michael Perry, new product development manager is Thompson & Morgan’s ‘Plant Hunter’. Michael works hard to seek out new varieties from around the world, and sees 100s of new hardy geraniums each year.

“Geranium ‘Rozanne’ has certainly made a name for itself in gardens up and down the country, quickly becoming a staple feature of any border display. Who could do without its 6 month flowering period, unfussy attitude and azure blue flowers, produced in a continuous procession from May to November? Plants are entirely bullet-proof, super hardy and will tolerate pretty much any UK soil. ‘Rozanne’ is a great investment too, as that incredible 6 month flowering period comes every year for 10 years or more!”

Peter Freeman, a plant buyer at Thompson & Morgan began his career within the Blooms of Bressingham company. He has seen new plant introductions such as ‘Rozanne’ through from the selection stage to the garden centre bench.

“I was fortunate enough to be involved in the trials of new plants at Bressingham, so have seen this plant for over 15 years, even prior to i’s public launch. Geranium ‘Rozanne’ is a totally hardy perennial, which will flower superbly from late May to November. Many plants claim to flower for such a long period, but will actually only ‘flush’ periodically. ‘Rozanne’ flowers prolifically from beginning to end. The flowers are an amazing, vibrant blue with vivid veins and the foliage is clean, tidy and not susceptible to any pests or diseases. Easy for anyone to grow in sun or shade, bees love them, plants are also ideal ground cover – there are too many good things to say about this plant! I consider myself to be in a privileged position and get to see most new plant introductions from across the world, but I do not think any plant has come close to beating Geranium ‘Rozanne’ in the last 15 years.”

    This certainly looks a very nice Geranium, and gets my vote. Thank you Thompson & Morgan for putting this one out for vote.

  2. Sue Taylor says:

    I wholeheartedly agree with this recommendation. For me Rozanne is a perfect garden plant. I grew it in my garden in Maine where it withstood much colder (and higher) temperatures than we have in the UK and here it behaves wonderfully, flowering for a very long period and keeping to its allotted space. The flowers are large, a beautiful blue with a lovely white eye, the foliage too is pretty. A superb plant.

  3. Patricia Green says:

    I have just listened to the video about Geranium “Rozanne”. It sound almost too good to be true. Just what I have been looking for. I shall place my order today and await delivery with anticipation.

  4. Joe S. says:

    I have a problem with pink hardy geraniums spreading like weeds in my garden. Does this one behave the same way?

    • Rebecca Tute Rebecca Tute says:

      Dear Joe, many thanks for your comment. Peter Freeman has just emailed me to say that, while many geraniums do self-seed, ‘Rozanne’ doesn’t and will not spread in your garden. I hope this helps.

  5. Doreen says:

    I bought this plant last year after seeing it at High Grove gardens, certainly gets my vote.

  6. Catherine H says:

    This sounds like an ideal plant for anyone wanting long lasting flowers in the garden every year.
