Uses

Edible
Rose hips are occasionally made into jam, jelly, marmalade, and soup or are brewed for tea, primarily for their high vitamin C content. They are also pressed and filtered to make rose hip syrup. Rose water has a very distinctive flavour and is used heavily in Middle Eastern, Persian, and South Asian cuisine, especially in sweets such as barfi, baklava, halva, gulab jamun, gumdrops, kanafeh, nougat, and Turkish delight. Rose petals or flower buds are sometimes used to flavour ordinary tea, or combined with other herbs to make herbal teas.
Ornamental
The majority of ornamental roses are hybrids that were bred for their flowers. Iceberg is a favourite because of the continual flowering through the season.

Problems

Wild roses are host plants for a number of pests and diseases. Many of these are also shared with other plants, including especially other genera of the Rosaceae. Cultivated roses are often subject to severe damage from insect, arachnid and fungal pests and diseases. In many cases they cannot be usefully grown without regular treatment to control these problems.

Companion plants

Members of the onion family such as chives, ornamental alliums, and edible onions, are rumored to increase the perfume of roses, ward off aphids, and prevent black spot. Scented geraniums (Pelargonium), rue (Ruta), feverfew (T anacetum), parsley (Petroselinum), and thyme (Thymus) all may help ward off Japanese beetles and aphids. Marigolds (Tagetes) may also repel pests and encourage growth. Try ornamental and culinary sage (Salvia), anise-hyssop (Agastache), Russian-sage (Perovskia), lavender (Lavandula), yarrow (Achillea), oregano (Origanum), catmint (Nepeta) and calamint (Calamintha). Oddly enough, tomatoes allegedly prevent black spot, but not many people will be inclined to combine roses and tomatoes. Lavender (Lavandula) and catmint (Nepeta) are good at keeping rabbits away. Yarrow (Achillea) may attract ladybugs who in turn feed on aphids. Remember to plant rose companions at least 30 cm away from your roses so that you do not disturb their roots.
