Hi Frerckles..
The Floribunda roses are planted in pots in spring and the pots are moved outside when the risk of hard frost is past. The roses stay outside in the fair weather and sunlight through summer and early fall. The most obvious class of roses suitable for culture in pots is the miniature rose class. The plants are small so the pots they require are small. The pots must move their fine fragrance and beautiful blossoms nearer your face. Thank You.
