Where have you got it planted and is it in full sun because it needs to be.

Possibly a bit early in the year yet? Our grasses are only just starting.

Yes, they often take a year or two to get going . . . had mine (in full sun) for 3 years and this is the first summer that it's flowered.

@Moon growe - Yes, it's in full sun.

@Bulbaholic - This one should begin to flower in May / June.

@Sheilabub - That's encouraging. Hopefully mine will do the same!

Thanks all, for taking time to reply - really appreciated. :)
