Hi Jane: I don't know about soil, but some of my bulbs definitely change color from year to year, and I am certain it is not from stray seedlings finding their way into the pots. Color intensity of Triteleia laxa changes, but the most dramatic color differences have been in Rhodophiala. I have a pot of R. chilensis grown from seed that were clear red, and were identified as such when I got the seed from Flores and Watson. The original bulbs are still with me, but this year and last year they are yellow diffused with red throughout. There is no sign of virus or any other problem. Oxalis flower color can change quite a bit. At first I thought it was from seeding from adjacent pots producing new colors, but I now see that they actually change, not just in intensity, but also hue. The soil is not a factor here, I have them in the same mix, but temperature varies from year to year, and that could be a factor. Some colors seem to have 'evolved', changing gradually each year until they hardly resemble the original picture I have of them (Oxalis obtusa Peaches & Cream, is, unfortunately, one of these).
