(Mature Size: 48"T x 70"W)
'Empress Wu' is a seedling of 'Big John' that is colossal in size.
This semi-upright grower forms an impressive mound of thick, corrugated green leaves.
Leaves have a glaucous coating in spring giving a blue-green appearance.
The wavy green leaves of 'Empress Wu' are said to be the biggest hosta leaves ever!
Can grow bigger than listed size if in ideal location of fertile soil with good moisture retention.
If grown in poor soil expect a clump 30"T x 50"W.
Be patient with this hosta. It gets big but not overnight. Will take 5 to 8 years to reach a mature size.
Very pale lavender flowers appear in mid-summer.
We have a cream-margined sport of 'Empress Wu' called 'Wu-La-la' that has the same size with a more colorful leaf!
