Unknown Escapee with Yellow Flowers
These glabrous plants were spreading from a yard into a ditch. They had short rhizomes and also appeared to be spreading by seed. Clumps were about 50 cm tall. Leaves had hollow, flattened petioles that were grooved on one side, broadly winged at the base, and ranged to 25 cm long. Blades were reticulate veined, had rounded tips, undulate margins, cordate bases, dark green and glossy surfaces above, medium green and glossy below, and ranged to 8 cm long by 7 cm wide. The striking flowers averaged 4 cm across, had 3 sepals and 8 petals. Sepals were strongly cupped and greenish-yellow. Petals were bright yellowish-green, quite glossy, and had crown-shaped patterns toward the base on both surfaces. Flowers had about 30 stamens and 20+ styles/ovaries that were covered with bright yellow pollen.
These are surely non-native, and have escaped to distances of around 50 yds. Since there are large distances between some clumps, the seed appears to be viable.

Comments (5)A location would have been useful. However, Abutilon indicum is a tropical plant. It has never been reported as escaped in the US, and has much smaller leaves than those shown in the photo. That looks like typical A. theophrasti to me....See Morejekeesl (south-central Arkansas)

4 years agoIt's very pretty but It's a thug. Around here it makes a solid cover over any damp, shady ground in the spring, and it's one of the earliest flowers to bloom. The only good things about it are that it IS an ephemeral, so it completely dies back by summer; and it's low; larger herbaceous plants like skunk cabbage can grow up through it. Of course where I live is pretty much a living
encyclopedia of invasive weeds, but this one is tough even by those standards.
