How to complete them
You can collect 10 Roses a day I would advise you to collect the Blue, Glitter, Pink, Green, Lavender and Orange.
That way you do not waste the ones you claim (It is better to get 2 Orange for example rather than a Red and a Yellow as they would convert into 1 Orange Rose and you have used up 2 outof your 10 a day allocation.
