Unhappy day lily

Grumpymum

The flowers on my day lily are rather small and a strange pale brown colour instead of the nice yellow they've been in previous years. Any idea what may have caused this? Could it be the late cold snap we had? Maybe they are a bit overcrowded and need splitting?

I think hemerocallis/day ilies need splitting every 3 years or their roots become hopelessly congested and flowering quality and quantity diminish.   Water the clump generously and let it soak in for half an hour and then dig it up with as much of the roots as possible. 

Soak in a bucket of water to loosen them then cut or pull apart to make fresh new clumps.  Re-plant what you need after improving the soil and pot up the rest for swaps and spares.   Keep watered while they recover.  The ones in pots will appreciate some shade for a week or 3 till they settle.

The flowers look like an Iris to me, and so do the leaves, possibly I. foetidissima. The plant behind it, with the V-shaped cross section to the leaves, looks like your actual daylily.

Oh yes, just googled the iris and I see what you mean. I'll have to dig it all up and try and separate them. At least the ground is soft after all the rain!

Thanks

It does look like Iris foetidissima and the flowers are brownish and small. Looks all good to me.

I think they're right.  No photo when I posted as it was a bit slow loading here on snail-net.
