It's 2 deg here (feels like -3 in the easterly wind) and likely to stay
that way for a few more days yet. I have an unheated greenhouse available
to me. Is it still too early to sow the Sunrise seeds, do you think (they
are for outdoor growing)?

For outdoor growing I usually plant mine in mid April.
You don't want them too big and lanky before they go out first week of June.
