  1. 24/7 Osteospermum 4D™ Series 5 pc. Collection

    The newest take on osteos, Roberta’s 24/7 Osteospermum 4D™ Series is by far the coolest and most impressive collection of osteospermum out there! This collection of five gorgeous two-toned colors is not only in a range of colors brand new to osteos, the flowers on these 4D™ series osteospermum are truly two flowers in one, with the bottom layer exhibiting a traditional osteospermum which is then capped with a secondary frilly flower on top. But it is time that gives it the fourth dimension (and thus the name 4D™) because these osteospermum stay open all day and all night, a trait brand new to these osteospermum! If you’ve ever grown osteospermum before, they always close at night, or even on an excessively cloudy day they’ll even remain shut during the day, not these guys. Our 24/7 Osteospermum remain smiling in bloom all season long, giving you up to 3 months of pure flower power with a vast amount of flowers, up to twice as many flowers per plant as traditional osteos.

  • 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.
