In a traditional Rose Catalogue the bush roses are split into Floribunda and Hybrid Tea roses. We no longer do this, as with modern breeding it is often very hard to define which category a variety belongs in. Both serve the same purpose in the garden. They provide colour, perfume and happiness as we look at them in beds, borders, hedges and mixed plantings. The only rule in selecting which varieties to mix together is the rule that says 'Do I like this combination?'
It is not relevant that 50 to 100 years ago (when the varieties were very different from those we plant today), rose growers considered it a folly to mix Hybrid Teas and Floribunda bush roses. We have shaken off those restrictive shackles of the past and can allow ourselves to indulge in unbridled hedonism as we mix the roses together that we personally adore.
