Something scrophulariaceous

[treecreeper]

Several of these have appeared in the gutter just down the road. The flower is 15mm x 15mm from the front and has a slender pale brown spur, 8mm long and curving downwards. Any ideas please.

Possibly a Nemesia.

I'll go with that, Nemesia caerulea, a garden escapee probably.

Thanks for these....definitely Nemesia and very likely Nemesia caerulea as Teresa suggests. Google shows another candidate Nemesia foetens but this looks so similar to caerulea it might be a synonym

I didn't expect this plant to come up a second year, more so as the gutter it's growing in is outside a private school with much parking of Range Rovers going on. But it's made another appearance:



My question is, how many successive seasons will it have to appear before it becomes botanically significant, i.e. worth recording? In other words, how casual is Casual with a capital C?

On the subject of roadside gutters I spotted this American Galingale on the way home:



I'll keep an eye on this one as well as the Nemesia. Gutters are worth observing.
