Livingstone Daisies

Can anyone help me with my livingstone daisies.I grew them from seed and started this week to harden off.Put outside through the day.
But noticed that most of them have a red colour developed on the leaves.
Unsure if they are okay to plant,or has cold got them.

 

Not something I've ever grown @tattie , but if they're still very small, then yes - it could be that. It's quite common for cold weather to affect foliage on young plants that have been undercover and then put outside, but unless it's very harsh, or prolonged, it doesn't usually cause major problems.

If you can post a photo of them that will help though.

 

I think it's a reaction to stronger light and possibly uv.
Most succulents and cacti do this, they often stop growing until they turn green again.

 

@tattie - we are a Livngstone Daisy family and have grown them for 20 years or so. Mostly from seed but just occasionally, bought in plants from a local independent garden centre when we’ve missed the boat in raising our own plants.

For the ones we grow, I would say a reddish hue to the leaves was normal. As they are succulents, I think they have a preference for poor quality soil and too much water can be damaging so I wonder if that’s the reason why yours aren’t to be expected.

 

Ah - almost the opposite to the cold effect then @pete ?

 

Well I wouldn't say the opposite, it's still a reaction to a change in conditions.

 

Will they be okay to plant ?
Picture taken for correspondence.
Thanks everyone for help.

 

Thanks for help.Do you think they are worth planting.

 

They are definitely worth planting, nothing wrong with them, they look good and strong.
