Rose: In the February Flower Agenda 2019
As the undisputed number 1 amongst the cut flowers, roses provide colour, scent and beauty indoors in the month when nature is still only hesitantly getting started. This Valentine’s essential is a real stunner, available in many colours and shapes from a spray rose to a solo star. With new varieties being added every year to enhance arrangements and bouquets.
The rose is a member of the rose family and includes some 300 species in the wild. The number of bred cultivars is estimated at more than 30,000. Roses have been blooming on Earth for a very long time: fossilised remains of wild roses have been found which flowered 40 million years ago. The plant was first used as an ‘ornamental rose’ some 5000 years ago in China. Until the 18th century there were only white and pink roses. Only later were the red and yellow varieties added.
The choice of over 600 varieties means that the range of roses is large and rapidly developing, with new cultivars added every year. Alongside classic single stem roses and spray roses, there are roses with ‘grass hearts’ where the base of the flower grows through the flower, and roses that resemble peonies. To make themselves stand out, increasing numbers of rose growers offer unusual colours and shapes alongside their classics.
Valentine à la carte
In these times of diversity, it’s a nice idea to adopt a more open approach to Valentine’s Day.
- For those who love the classics there are always red roses, possibly mixed with white.
- For a more modern approach mix red roses with pale pink and bright pink roses.
- Love between BFFs: pale pink roses or mixed roses in all colours.
- Committed LGBT+++ love: rainbow roses!
- Millennial and centennial love: a field bouquet with grass heart roses.
Care tips for professionals
- Use vases or containers that have been thoroughly cleaned, and use clean tap water. Add cut flower food to the water in the correct concentration. Special rose food is best.
- Remove the leaves that could end up under water from the stern to prevent the growth of bacteria. If possible leave the thorns on the stems. Wounds on the stem will encourage the growth of bacteria, which will affect the vase life.
- Cut approximately 3 to 4 centimetres off the bottom of the stem with a clean and sharp knife or secateurs. Then place them in a vase or bucket immediately.
- Regularly check the water level and top up where necessary. Keep the roses away from sources of heat such as heaters or the sun. Never get the rose flowers wet with a plant spray; this will encourage the fungus botrytis.
- Roses can be stored in the cold store at 2 to 4°C. However, ensure that the roses cannot get damp due to excessive humidity or from condensation on the cellophane. This will also encourage the fungus botrytis.
Care tips for customers
- Place roses in a clean vase with clean water.
- Add cut flower food to the water for a longer vase life.
- Trim 3-5 cm off the stems diagonally with a sharp and clean knife.
- If possible, leave the thorns on the stems.
- Regularly top the vase up with tap water.
- Do not place roses in a draught, in full sun, near a heater or beside the fruit bowl.
