Artificially grown roses, that travel hundred of miles to reach Ireland, are not going to last very long once bought.
In summer, I like to cut a rose or two from the garden before I visit one of my lovely ladies.
Wild Edric is a tough, reliable and healthy rose that thrives in my garden and the fragrance is very strong.
If they are freshly cut they will last a couple of weeks.
If they are bought from a store, try to mimic the conditions where they were before.
Not too hot, not too cold.
Anyway these is not the season for roses.
At this time of year, try buying instead, daffodils, magnolias, camellias, snowdrops, etc.
