  10. 2 in 1 Combo Mandevilla 2 pc

    Probably the most iconic flowering vine is the Mandevilla and one of the reasons is because it seems to bloom like clockwork right around July 4th every year gracing patios, porches, trellises and fences with glossy foliage and gorgeous trumpet shaped flowers. Its bold and showy elegance is also a favorite because of its ability to grow like wildfire with extended bloom life and that is why it is able to make such a statement in containers as well as landscapes and borders. But per usual, Roberta’s takes it a step further with its 2 piece 2 in 1 Mandevilla Collection – because each piece actually contains 2 plants, one pot has both Red and White Mandevilla planted together while the other has Hot Pink and White. That means when you plant them, your plants will bloom enormous four-inch wide red and white flowers from the same pot or same spot in the garden! We recommend using a blue pot for an All-American appeal. Their vigorous habit can be both bushy and trailing making them quite versatile whether they’re planted in the garden, containers, or even window boxes.
