Agate Scarlet Vining Mandevilla

The Agate Series is a part of the Diamantina™ Collection of genetics bred by mandevilla and dipladenia expert Lannes of France. These sun-loving, traditional-type, vigorous mandevillas are earlier to bloom, and they have increased branching and blooming capacity versus current market competitors. The series offers extreme heat, drought and bad weather resistance. Mix Scarlet and White for a showstopping combination. Great for in-ground planting, hanging baskets, patio or garden containers, and in mixed combinations. Support, such as a trellis, is required. 
Very large blooms that are a true scarlet color!

  • Product Story
    • The Diamantina™ Collection of mandevilla/dipladenia, bred by DHMI of France, encompasses world-class genetics for their vining and bush varieties. Mandevilla sanderi was discovered in 1840 north of Rio de Janeiro, Brazil. The Diamantina region of Brazil is historically known for diamond mining. Now in the mandevilla/fipladenia world, Diamantina represents a product line as exquisite and elegant as fine jewels. Every series in the collection is a heavy bloomer that begins earlier than most and thrives through the hot Summer months. In addition, each has its own special and unique qualities. Offer your customers something exceptional: offer them Diamantina, the Jewels of Summer.
