Because of our long growing season, we experience the development
of huge rhizomes under Victoria crowns that ultimately lead to
their demise. The plants grow up out of the soil, the rhizomes
rot at the base, feeder roots can't reach the soil and the plants
decline. Perpetuating them over more than one warm season is
very tricky since the timing of either pushing them over or "chopping
and dropping" them has to be perfect. See Extending
the Life of Victoria
These younger plants seem not as stressed in cold conditions
as overgrown older plants. The vigor of youth? Not having to
deal with the large rhizome and a struggling root system? Does
this tell us something new about the cold tolerance of Victoria,
particularly the hybrids?
How nice to have flowers occasionally in winter! 'Adventure'
has bloomed in January, February and March 2008, though not with
the frequency of summer.
The sample and our experience are relatively small so far,
but we plan to try more plants in the fall of 2008 for winter
flowers if we have spare plants available.
