The one plant that says summer like no other is Primula florindae, the giant or Tibetan cowslip. As the largest primrose, it makes its garden presence known by sending up stiff flower stalks to nearly three feet topped with umbels of fragrant, tubular, bell-shaped flowers. Their sniffarific, spicy-sweet fragrance adds to the joy of a summer’s eve as it wafts through the garden. Flowers are mainly a bright chrome yellow, but plants can be obtained with flowers in varying shades of orange. Discovered in southeast Tibet by the acclaimed plant hunter Frank Kingdon-Ward, the plants are named after his first wife, Florinda. As such an outstanding garden plant, it has been given the Royal Horticultural Society’s Award of Garden Merit.
