Grasses (Stipa)
« on: July 20, 2007, 09:21:31 AM »
Hi, I have a problem with differentiating between two stipas growing in a friend's garden. She claims that one is Stipa capillata and the other Stipa gigantea. Her capillata is said to have very twisting awns, is that a significant characteristic of the species? It is at present 80 cm high. And her gigantea is 140 cm high with supposedly wider leaves than capillata. I enclose 3 pictures of would-be capillata and 2 of would-be gigantea. Do please help!

Regards, Barbara.

Capillata(possibly)




Gigantea (doubtful)

Hello, Barbara, welcome to the Forum.
Since my ignorance of grasses is even greater than my ignorance of ferns, I cannot assist you... there will be others here who can, thankfully!

Back in the early 70s many of us were well aquatinted with grass. Nowadays  we are old and boring and just cut it when we must  ;)

Back in the early seventies I was very busy with aquatints, and etchings and lithographs.... wish I'd known you then, Fred!

I am very "off" grasses at the moment, since the wee dog had her horrible injury on a cut stem of a Miscanthus.....sharp as a knife, nasty thing!

I think the grasses shown are Carex 'Frosted Curls' and Stipa tenuifolia/tenuissima

Well, no :) I grow both of these, being a novice grass collector, and you cannot admire the panicles of Frosted Curls or Stipa tenuissima at four feet off the ground ;D

The flowers (spikelets, glumes and all the rest of it) are definitely more like my notion of Stipa gigantea - more gigantic :) and not as hairy as in pictures sent by me. Thank you Mark, this is one step forward!

In a couple of days - I have asked my friend for the photos. So a little patience, please :)
