My stargazer lily plant has bloomed 6 years in a row and are the typical beautiful pink color. This year when they bloomed they are all white, not even a tint of pink or any other color. I am confused and devastated. They are potted and outdoors but have always been and always bloomed pink. Can you help me understand what happened and will they ever be pink again?

Liliums do not change into a different type of lilium. Sometimes pink lilies can fade to a white or lighter shade of color if an oriental lily is exposed to extreme heat. Do you have any pictures of what you are seeing as compared to previous years?

Years ago my aunt had a mixed color bed of irises. One year she asked me why they all turned white.
I didn't have an answer then but another summer I planted some lilacs for her and found out how poor
the soil was. I was never at her house to see the lilacs bloom, but they made very little growth. Planting them showed me that the "soil" was the sandiest I'd ever seen, and I guessed that the irises had used up
whatever nutrition had been there.

My old bearded iris have all turned white instead of the many colors I had. Why?

have you used any type of weed killer in the area?

Iris do not turn colors. They are genetically forced to bloom the color they are supposed to be. It may be that you had a white one that was more vigorous than the other colors and it choked out the others.

I'm afraid this is the Lilium (Lily) forum and so you may not have much relevant discussion to your question about Irises. Frillylily has the most likely answer - the white one was probably the most vigorous.

Some other possibilities are discussed on the Iris forum in threads such as this one:
The thread "Identification and MISidentification" in Irises forum

I have only had one type of lilies whichbare stargazers. This year at least 1/2 the blooms are stark white. These same plants were very typical pink lasr year. Any actual plant scientists in the crowd that can explain this phenomenon? The ones that were typically oink where quite large and have come and gone

I bought stargazer lillies this year. They have started to bloom and are white. The picture on the bulb package was pink. What's up with this?

The package likely supplied you with the wrong bulb, instead of the one that was intended. There seems to be a high number of errors in some of those Dutch packages. Can you contact the place that you purchased it and ask for a refund if you provide them with photo documentation.

I have had plants with colored flowers bloom white due to a problem with the soil. However, the entire plant was stunted and struggling, and it was obvious there was a problem. Too much phosphorus in the soil caused my issue. Adding nitrogen gradually corrected it.

Another explanation for things flowering with unexpected colors is squirrels and chipmunks. They don't just move tags. I swear there are more of my neighbors' tulips in my yard than theirs. When I plant lilies, I always plant daffodils with them so the squirrels will leave them alone.

@cpq19tdh I have no doubt magnolialover is right about mixed up bulbs in packages meant for the general nursery/garden center market. Case in point, last fall I came across an entire crate of 'Stargazer' lilies at a very popular nursery. Six bucks per bulb as I recall. But they were not Stargazers and I told them that. Stargazers are oriental lilies and their bulbs are very different looking from non-oriental lilies. All of the bulbs looked like trumpet or orienpet lily bulbs. So of course I took on the challenge and bought one just to see if I was lucky and got some very rare expensive lily at a cheap price. I'm looking forward to seeing what shows up!

If you scroll up to blwilson1979's post from 2019, ( @blwilson1979 ) :

The white and the pink lilies are two different cultivars. The pink lily is upfacing and the white lilies are out to down facing. This is a genetic difference. Also perhaps a slightly different bloom time for the two types of lilies.
