Small palmate foliage, and pale pink, darker eyed flowers make for a tall, airy, diaphanous, months long blooming perennial. Stems annually to 4-6’. Yes, this will likely get rust, but if you’re not concerned about other Malvaceae the foliage is so small that from a distance you won’t notice. It will also self sow to some extent, but seedlings need 3 years to get create a presence and deep roots can make moving a challenge so move ‘em while they’re young. Hardy to Z5? Quart pot.
