I think I was misunderstanding your description: quote: "started medium-light yellow and became pale apricot" Try doing a search on Help Me Find for a rose bred before 1980 which is yellow and highly fragrant. Maybe something will ring a bell. Good luck.

It's very hard to see much in that picture. I can't see any yellow there at all. Can you get a better picture of a fresher bloom? Also pics of the buds, cane, leaves and whole plant would help. As for changing color, a lot of roses will fade as they mature. It does not mean there is anything wrong with the rose.

I think you all are right that it is a brassica. The closest I have found to it is Brassica juncea but even it isn't an exact match. The veins in the leaves of mine are darker than the photos I found online, plus there is the white flower vs yellow. btw, the wrought iron thing above it is a candle holder.

Regarding horticultural selections generally (and not lilies in particular) renaming has gone on a lot over time. Especially with old varieties that have been grown frequently over large areas published accounts may list a multitude of synonymous cultivar names that have been coined by various parties. (Even some wild plants being treated by the supposedly sober realm of professional botany may rather often have been subjected to repeated publication of differing botanical names). And trademarking and patenting do not confer 100% protection of commercially "owned" plants, as some selling of what are clearly examples of such under new names fabricated by second parties does appear to occur.
