Hi Tony,

Your information will definitely help people on the West Coast 
wanting to grow Lycoris. Both L. radiata and L. aurea (especially 
radiata) are relatively easy here and in the Sacramento area with 
adequate irrigation, both in pots and in the ground. L. longituba 
will also flower here in pots. I'll have to try L. "haywardii" here. 
It would be nice to get one of these spring-emergers to grow and 
flower successfully in the ground. This is definitely Amaryllis 
belladonna country and most, if not all, of the spring-emerging 
Lycoris here seem destined as potted plants.
