From Liberty:
The Scilly Flora print is reworked from children’s drawings and inspired by the flora of Tresco, the second-biggest island of the Isles of Scilly in Cornwall, England. True to its island flair, the print is nearly Hawaiian, underscored with classic heritage notes that Liberty fabric is known for.
There's a cute article in the Scilly Times news website about the project.
Not sure the name of this colorway.
