Virused Bulbs

Is there any data on how long plant viruses can hang out in the soil?  Last
year, I grew some Gloriosa superba from a commercial vendor.  The plants
exhibited color break in the flowers and some oddly deformed foliage, so I
threw them out at the end of the season.  I now have some new plants I grew
from seed that came from Silverhill, and I wonder about locating them along
the same fence as the old ones.  The questionable plants were in pots, but
roots may have invaded the ground.

Same deal with Cannas in a flowerbed.  I ripped out some clearly virused
Canna about five years ago and would now like to replace them with
virus-free stock from Tony Avent.  Should I pick a different location?
