This plant was growing in a large border in a public garden. A trailing plant, it had leaves like a small fig leaf, but it was the shading of the flower colours which were particularly striking.
Thank you in advance for any suggestions.
It's Ipomoea lobata (the Spanish Flag plant).
I've got some in a pot growing up an obelisk by my front door
It looks very much like Mina lobata 'Firecracker'
Spanish flag I think. I spotted it on a seed website this very morning.
remember that if you want to grow it, it is a half hardy annual, so plants should not go outside until after the last frost [ IMO, probably not till late June, as it is very tender ] It will die after the first frosts of Autumn.
Wow!!! Thank you, everyone for your quick responses. A definite purchase for next season.
