I purchased Silver Streak in 2015 and received two large healthy rhizomes which were planted directly in the ground in mid March (early autumn). They both bloomed 7 months later but one bloom was taller and didn't look like Silver Steak.
I asked Tempo Two what the other flower is and was advised that there are variations in the flower patterns and that they think both rhizomes are Silver Streak. The pale rhizome did not produce any increases until months after the blooms had finished and I have been waiting 4 years now to see if the blooms would look normal in the future. This year's blooms look pale like the blooms in 2015 and the height of the stem was shorter (about 52cm compared with 62 to 82cm for the normal Silver Streak stems).
I wish I could conclude that the pale bloom will not revert back to looking normal but there is one factor that may have affected this year's bloom. In September this year when the bud was forming in the base of the foliage, the pale Silver Streak foliage was covered in bugs and I sprayed it with soapy water. I noticed that the base of the foliage lost some of its green colour a few days after I sprayed it. This is a recent photo of the foliage which still looks unwell.
I have also moved the rhizome once since 2015 and it's current spot has become quite shady. This may have contributed to the shorter stem.
Does anyone have any thoughts on whether this pale version of Silver Streak is Silver Streak or something else? Could it be a sport of Silver Streak or a seedling of Silver Streak?
Edit: I forgot to mention that this year one of my Silver Streak blooms had splotches like the pale Silver Streak but not as pale.
