Negative | On Jun 19, 2019, goedric from Newaygo, MI wrote: So far (3 years) very very unimpressed. I purchased a dozen from multiple sources and have planted them in multiple locations... they are still tiny. Leaves are weak and the plant falls over. I have some next to Sum and Substance as well as Blue Angel (as well as several other varieties) and this is the only hosta that is under-performing. I left 3 in gallon pots through the winter along with other varieties... the winter was bad (zone 5 but temps were more like zone 4). Of the 20 hostas I left i pots... 3 died... all 3 were Empress Wu (Proven Winners, Shadowland Empress Wu to be specific). None of the Empress Wu in pots made it through the winter. I am about ready to yank all these embarrassing hostas... 1 more year... hoping they are doing something underground |

Positive | On Aug 1, 2016, Roziz from Ottawa, My Empress Wu started with a stub, planted in the shade of a rose bush; now it is four feet high and wide, has grown out of the shade and takes full sun for a third of the day with no burning. It has smaller hostas thriving underneath its shade casting 'branches'. Very architectural and works in a difficult spot - an odd mix of shade and full sun. |

Positive | On Feb 29, 2012, marywalters from Holland, MI wrote: There is a handy saying that truly applies to Hostas - especially large one like Empress Wu - Sleep, Creep, Leap - 1st year they put on roots, 2nd year they are a bit bigger. By the 3rd year, they start to strut their stuff! Empress Wu is well worth the wait. |
Positive | On Aug 11, 2011, dahlia10 from Ottawa, I'm impressed with the Empress! I bougth this little 2 leaves plant this spring.Now it has 12 big leaves and has almost the same size as my 2 year Sum and Substance! |

Positive | On Jun 4, 2011, Joe904 from Kalamazoo, MI wrote: I purchased two Empress Wu at an end of season sale last year in 1 gal containers. They came up and have been growing quickly this year - each has 8-10 large leaves and the plants are now about 24" high and 30-36" across. They are planted in full shade in my woodland garden. So far I am extremely happy with their performance. |
Neutral | On Oct 8, 2010, lillian215 from Quincy, IL wrote: My Empress Wu was planted two years ago and is still very small with only 2 leaves, but it seemed to "bolt" in the center this year with a couple new leaves and then stopped and was so weak it fell over. It never did bloom. My soil is the best and all my other hostas were on "steriods" this year. Does anyone know what is wrong? |
Neutral | On Jul 13, 2010, mothermole from Deer Park, IL (Zone 5b) wrote: I have had this plant since the introduction in 2008. My experience differs from what is listed here at Daves. My plant is very, VERY slow growing. I thought that by this year (2010) it would pick up speed in growing but it hasn't even doubled in width and nothing in height. I am hoping that next year will be the year for some major growth! |
