  3. Fragrant Everblooming Disocactus Duo 2 pc.

    A close relative to epiphyllum, our Fragrant Everblooming Disocactus is a beautiful, long flowering easy to grow cactus collection for everyone in the country. Just like the epiphyllum, it’s a plant that keeps on giving – they can be propagated in mere seconds to make brand new plants in a cinch. Outside in the summer and indoors in the winter, this collection of jungle cacti native to Mexico is the best flowering, thorn-less selection of cacti we’ve ever had. Their sweeping, overflowing habit makes them an excellent choice for hanging baskets and elevated pots. Our Disocactus will begin to flower from an early age, typically the first or second season and bloom for months on end; whereas epiphyllum will often take four or five years to produce a steady stream of flowers that last only a few weeks on the plants. Our two-piece collection of Everblooming Disocactus includes one Empress Josephine Pink and one Napoleon Bonaparte Yellow

  5. 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.
