Nierembergia-Cupflower

Propagating Nierembergia or Cupflower can only be done by cutting or seeding or layering and are best suited for Zones 8 and up otherwise it is an annual at least in Zones 3,4 & 5. Depending on soil conditions, a well draining soil in full sun, it can be a great self-seeder. It is a distant relative of the petunia, but comes only in white and purple and reaches a height of 3"-6" and in Phoenix will bloom from March until October. Cutting should be taken in the summer and if planting seeds give yourself 12 weeks before the last frost before transplanting outside. It prefers a moist soil but is drought resistant which is odd. Cupflowers are hummingbird magnets. A better alternative then petunias.
