I love this grass, and it should go very will with Hosta. I only have 2 varieties so far, 'Aureola' and 'Albo-striata,' but I can honestly say I've never seen a variety of Hakone I didn't like. It all depends on which color scheme you fancy.

Goggle Images is a good way to look at them all:

Lots of online vendors carry 'Aureola' but fewer carry other varieties. Digging Dog and ForestFarm both have better selections.

Hi. I have 2 Hakonechloa macra 'Aureola' plants, one of which is 7-8 years old,and the other one around 4 y.o. They
are in different parts of the garden but do not receive
much sun. They have never been mulched but received compost
and a mix of kelp, bone meal and leaf mold sprinkled on
top when planted. Initially, they were watered daily but after that only as needed during hot spells.
One thing the grower told me was not to use spray near
the grasses or other plants. People experience a lot
of casualties from too concentrated applications of ferti-
lizer as well. I know a lot of people have had problems
keeping these grasses alive, and there may be other
reasons why they don't survive. Overall, the golden culti-
vars seem to be more fragile than the green varieties.
