I have have found this species difficult to germinate and have been unsuccessful in getting the small number of seedlings produced to maturity.

Towill (1983) found that seeds of this species stored at 1 to 3 degrees C germinated at 62% after 20 years.

Breeding

Watanabe (1991) found that 4.2% of varieties of this species produced 2n pollen.
