There is no way on earth I could choose a favourite colour! I just love roses, ALL roses. Whichever rose I'm looking at is instantly my favourite lol. I've got heaps of colours in the yard too. Pink, red, orange and pink, pink and white, white, yellow, and bright orange and red.
I have an assortment of different colours growing in my front garden. Some were chosen for colour; some for fragrance. I love the deep reds the best but if I had more room I would plant some of the more modern colours as there is so much more variety than when I first planted them over 40 years ago. I have replaced a few of them but won't part with my "Old Gold" as it looks like a small cabbage.
