Known worldwide for our vigorous, disease-free crops, Rancho Tissue Technologies expertly blends technology and true innovation to produce the finest tissue-cultured, custom-propagated plants, food crops, and medicinal plants in the world.
As one of the largest tissue culture producers in the world and the largest tissue culture succulents producer in the U.S. and potentially the world, we grow up to 4 million plants per year in our state-of-the-art, environmentally controlled laboratory and greenhouse. Led by Heather May and Susana Vanzie-Canton, our team of expert international researchers and scientists has been producing an exceptional range of plants for nearly 30 years.
Heather May founded Rancho Tissue Technologies in 1987 with a goal of supplying the industry exceptional quality plant tissue, including hard-to-find varieties. One of the few female tissue culture lab owners in the world, Heather has a background in molecular biology. Growing up in the family nursery business, she knows well the quality standards required for cuttings and stock plants, and shes applied that to RTT. The state-of-the-art, environmentally controlled lab now produces more than 4 million plants per year for customers worldwide.
Susana Vanzie-Canton joined RTT in 2007 as a researcher valued for her extensive experience in tissue culture, including developing plant tissue culture protocols and mutation induction protocols for several plant species. She oversees day-to-day activities at the company and ensures the continued growth of our line of tissue cultured products including succulents, foliage plants, cut flowers, perennials, tropicals, ornamental grasses and other virus-indexed plants available direct from us or through our worldwide broker network.
