hosta, ornamental grasses and water?

updated sat 26 may 07

Margaret Little on fri 25 may 07

I read that grasses perform better with restricted watering?
I would like to introduce a variety of grasses in my hosta gardens but I kn=
ow my hosta are not going to be too happy with less water and apparently th=
e opposite for the grasses.
Has anyone had experience growing hosta and grasses together with abundant =
water.
Too many hosta too water individually.
Is this scenario even a concern.

Hey, HI, Phil!!

I think that grasses SHOULD go with hosta! So I've tried many here in my zo=
ne 5b/6a garden in Buffalo, NY. And I've killed lots -- or rather, the wint=
er has killed lots. But you're absolutely right that the water requirements=
are the key to grasses' survival, it seems to me.... too much water and th=
ey won't live another year! I have a good number of hillocks out there of m=
ostly dead grasses that need to be moved. Frost hardiness seems to be most=
disastrous with any grass/grasslike plant which has RED, or bronze foliage=
. OR perhaps I naively choose annual grasses just because they're gorgeous=
with the hosta.

Roger Grounds' two books, Planthunter's Guide to Ornamental Grasses, Timber=
Press. 1998, and Gardening with Ornamental Grasses, Horticulture Publicati=
ons, Boston, MA, 2004 (with info from the '98 book) are pretty good, as is =
Rick Darke's The Colour Encyclopedia of Ornamental Grasses, Weidenfeld & Ni=
colson, Orion House, London, 1999. Rick is an American, living in Pennsylva=
nia, was on the staff of Longwood Gardens.

ANYWAY,

Grounds lists several grasses that "go with" hosta -- most seem to be not h=
ardy here. He seems to like banboos.

There are annual grasses -- Penicum, Pennisetum, Sorghum, Zea mays -- that =
are, well, annuals

Grasses that are reliable with hosta, here:

Calamagrostis x acutiflora (esp. 'Karl Foerster')
Deschampsia
Fescu
Miscanthus x giganteus (any miscanthus grows well here, with or without hos=
ta)

Grass-like plants that survive here, with hosta:

Carex (sedge) <-- grows especially well as they need fairly constant moistu=
re and cool shady conditions, and really appreciate WET soil while establis=
hing. Divides extremely well, and works in pots.

Hakonecholoa <--- yeah, but I haven't found the perfect spot for it. Mine i=
s barely hanging in there.

Leymus ("Blue Lyme Grass") <--- gorgeous spikes of glaucus blue, has surviv=
ed a couple years before giving up

Acorus < -- likes dampness, grows any where it can find water, very short s=
tature here, the gold / yellow varieties are nice with hosta, but may be sh=
ort lived

Ophiopogon planiscapus 'Nigrescens' <--- yuppers! everyone knows these!

Lirope <---- the green varieties seem to be most hardy here. The college wh=
ere I teach uses it under trees as a ground cover

Sisyrinchium (blue eyed grass) <--- gorgeous in a pot with well drained so=
il, as its in the iris family, doesn't want wet soil

Phormium (New Zealand flax) <--- also great for a pot ... many colors and h=
eights (one could make a small fortune selling this ... check out the price=
s at the nurseries!!

ry and the hosta are wonderful, but not turgid!!

Hi Carolyn,
Your weather sounds like what we had (add very windy yesterday). Yeste=
rday made it into the 90's. Last night it started to rain. It is a lovely=
sound. The hostas are loving it. Only trouble with the rain is the cool =
temps. High in the 60's. Maybe the rain will head your way (hope it doesn=
't ruin any Memorial Day plans).

I just found my copy of Rick Darke's TIMBER PRESS POCKET GUIDE TO
ORNAMENTAL GRASSES, Timber Press, 2004. Wonder what will be new in his
"... Livable Landscapes".
