The Best Plant of the Centenary - 1913 - 2013



This Royal Horticultural Society (RHS)  announced its "Plant of the Centenary" - the best plant introduced at the Chelsea Flower Show in the UK in the last hundred years (1913 - 2013).

Top horticulturalists helped to nominate the 10-plant shortlist and the public voted and decided that

Geranium Rozanne


is the best overall plant.  Right now, in August, you can see why they chose this plant - it is a sturdy perennial that requires little attention and is covered with beautiful, violet-blue flowers growing atop mounds of deeply cut, green foliage.

 It flowers in profusion from June to frost. Midsummer heat does not deter the flowers and the plants are spreading but not sprawling. It is mounding and can be planted above rocks and walls to great effect. The blue color of the flowers deepens as the weather gets cooler.

This is the true perennial Geranium that grows in full sun or partial shade (in the South and in the warmer areas of western Zones 9 and 10). It likes good drainage and can be in exposed sites.  It does not seem to be affected  insects or diseases and is not eaten by rabbits.

You can plant it in an informal garden, rock garden or in a gravel garden. My favorite way to plant Geranium Rozanne is to use it as an underplanting for roses. I find the purple/blue contrasts beautifully with Super Hero red shrub roses. I also like to plant it with pennisetum 'Hameln' as I did  here for a client's garden.

Thousands of people voted for the Plant of the Centenary from a shortlist of 10 - one for each decade the RHS Chelsea Flower Show has been held - and the beautiful geranium achieved the top spot. The shortlist was picked by a panel of horticultural experts from plants launched at the Chelsea Flower: Show:

  1. Beautiful garden photographs.

    I can appreciate them even more since I do not have room for a garden. Thanks for offering a place for nature and flower lovers to visit - even if through pixels across the ocean!

  2. Mix 1 tablespoon baking soda, 2 1/2 tablespoons vegetable oil with one gallon of water. Shake this up very thoroughly. To this mix add 1/2 teaspoon of pure Castile soap and spray. Be sure to agitate your sprayer while you work to keep the ingredients from separating. Cover upper and lower leaf surfaces and spray some on the soil. Repeat every 5-7 days as needed.
