While I explain in my reviews of Yellow and Purple how I planted these all too deep, these White came up as expected, after the Yellow, and my Purple was unexpected but nicely last to bloom.
These first bloom at a normal crocus height, and continue to grow taller. Some of them are as tall as short Tulips. I really like them, and a few of them are double blooming.
The only con I have is that the packaging has difficult to see information and only the product number, no color, nothing else. I got multiple packs so it was important to me to know what was what while I was planting, so I had to create a workaround to get my planting plan to work correctly.
