Lauw; I am glad you made this observation because I
had noticed some of the same behavior. On some Lycoris
I noticed "stalks" with a bulb at the base and another
formed above the lower bulb. I was having some trouble
deciding whether the newest bulb was the upper or the
lower and whether the plant was trying to get
shallower or go deeper. i have been trying to
hybridize Lycoris and dug everything from 1 year
seedlings, 2year etc. to my six year seedlings this
spring becaase I am moving the garden. In looking at
the age progression in the seedlings it seemed to me
that they were going deeper and deeper the older they
were. I have been reading about Lycoris this spring
and all me references were saying they bloom better
when they are planted shallowly. I was a bit confused
becuase the plants seemd to be telling me that they
like depth. The books I was using were zone 7-10
garden writers and my present garden is zone 5/6.
Could it be that in colder zones the plant pull
themselves lower than in warmer climates. Since I am
moving to a zone 7 I shall plant less deep in the new
garden but I am still confused by the action of the
plants. I hope next year to see the first blooms on my
oldest crosses.
