Over the years the Garden’s collection has grown considerably. The collection includes plants that are found nowhere else in the world, introduced through the Curator’s hybridization program. Hybrids are crosses between species (sometimes naturally, sometimes by human hands).

Our Curator, Brian Kemble, has created numerous hybrids throughout the Garden including Aloe ‘Hellskloof Bells’ and Aloe ‘Creamsicle’, Aloe ‘G.W. Miller,’ and ×Gasteraloe ‘Luman.’ Kemble is perhaps best known for his Aloe hybridization. His goal is to create aloes with striking flowers and foliage that are also able to withstand Northern California frost. In the coming years, Kemble hopes to make more of his hybrids available to the general public.
