In the San Francisco Bay Area, Gladiolus tristis begans blooming in mid-February, and is almost over by mid-March. It is only scented at night and into the early morning, but scents the entire garden. I also love to cut them and keep them in my bedroom because of their wonderful scent. These also reproduce on their own rapidly, and I have had to give away quite a few corms. This is a very easy to grow, beautiful plant.

Native to S. Africa. Fragrant, creamy to yellow flowers veined with purple. Blooms in late spring. No water in summer. Begin watering early fall. Likes well drained soil. Interesting shoots rotate as they grow, producing a twist in the stems. Tend to be floppy. Should be supported.
