Most gardeners are probably familiar with Nierembergia, or Cupflower. However, they are probably not aware of the difference in species. In the US, cultivars of the more common N. scoparia, such as ‘Mont Blanc' and ‘Purple Robe' dominate the Cupflower scene, but gardens are missing out if they haven’t tried N. linariifolia. It is a lesser grown species with a little more cold hardiness and larger flowers. The Bustani Plant Farm exclusive introduction ‘Taza Grande’ is a selection we made that has substantially larger flowers. It was the largest blooming individual out of a batch of seedlings from our friend Rolando Uria of Buenos Aires, Argentina. Its Petunia-sized blooms are white with a touch of lavender and yellow in the center and freely produced throughout the heat of summer continuing even after a few frosts.
