If you want to pick a bunch of fragrant roses for the vase it would be best if you picked them when they are almost fully open.
A rose in bud will not give out much perfume. Also a rose that is over-blown will have lost most of its perfume.
The best time to check for fragrance in a rose garden is around midday when it’s warm – when the sun has had a chance to coax out the perfume.
If the weather is too hot or too cold your roses won’t be able to give out the best fragrance. The rose is too busy protecting itself against the heat or cold.
A happy, relaxed rose is a fragrant rose!
Red roses were traditionally the roses with the most fragrance but more recently because of cross breeding, fragrance is to be found in roses of every shape and colour.
