Jewel Weed at it's peak.

Lovely!

related to impatiens...very tender too...the frost has turned them to mush.

Oh dear...oh well...next year. My Sweetpeas for next year have just germinated in the greenhouse.

not heard of this plant, but then there's so many i've not heard of! sounds good that it's so insect-friendly

Me neither Fran. It's lovely and bright isn't it.

is it invasive at all?

When the seed ripens (it forms in a pod) the pod POPs and sends the seed a distance from the parent plant. They enjoy very rich soil (well rotted compost as is found near old barns, henhouses and rabbit hutches!) but they will grow in any soil as long as it's relatively moist. If you find it growing where it's not wanted it can be easily weeded and will not return. It's on GoY as Impatiens capensis, Jewel Weed or Touch-Me-Not! ... <3

not sure how "rich" the soil is here, I've not enriched it yet and heaven knows when it was last done, so I think I'm safe from incursions!
