One of the first things we did on returning to France was to plant-up all the pots and planters. A home isn't the same without flowers.
We usually buy old-faithful Petunias, which will normally continue flowering until the frost gets them; but for some bizarre reason we couldn't find any. Instead I bought these Impatiens (below), which are OK; but not the same. We also have several potted Geraniums that have survived the winter and recently romped; they are now flowering like crazy.
I always go for blood red, with deep green leaves. It's the same with Roses, Geraniums, or Oleanders; I love that contrast. I'm not keen on pink or white; blood red is my baby.
We're only here for three months so no point putting in bedding plants. It's a different type of gardening, and the book is yet to be written. An opportunity for someone 'The 3 Month Garden'.
