Lilium formosanum advice

The short form of Lilium formosanum, sometimes identified as var. 
pricei, has long been popular with rock gardeners. It can flower the 
second year from seed, and I get the impression that people in 
cold-winter climates grow it as a biennial. I grew it only once; it 
flowered in the garden and did not reappear. Edward McRae wrote: "In 
subtropical climates L. formosanum can grow from seed to flowering in as 
little as six to eight months. In northern climates it generally flowers 
in October in the open garden and then falls victim to frost. This 
exhausts it; the little bulb is not very winter-hardy and rarely 
survives." He adds that this species is very susceptible to lily viruses.

Large amounts of seed are donated annually to the NARGS seed exchange, 
and presumably to the British ones.
