This one blooms in spring, as when these picks were taken in April but seems like I've also seen them bloom in the fall?? not this year though.

Hi Christine!

It has a certain chickweed look about it, I found one which has leaves I think the same, not sure if the flowers quite match up.

Cerastium beeringianum

Flowers on Minuartia drummondii​ look closer but it'd difficult finding photos showing the leaves well.. the flowers look bigger than the leaves.

It's somewhere in the family.

Hi Janet!

Now that you say that, yes it does have a chickweed look about it but like you say, the leaves seemed wrong? I'll keep looking to see if I can find which one.

Thank you a bunch for your help! I'll let you know.
