The rose is the HTA’s Plant of the Month for June.
Market research conducted by the assocaition has revealed that 49 per cent of Britons with a garden grow roses in them.
Blue Peter gardener Chris Collins said: "I suppose the choice of a rose as my favourite may be considered an obvious one when gardeners talk about plants - but the English garden is incomplete without one or possibly many.
"When I started my apprenticeship with the parks, the hours spent in the rose garden is where I first connected with plants in a professional capacity. However, my real love of them came much later when I began to import David Austin Roses into Japan whilst working there. These plants really just give and give and with the minimum of fuss."
