Grew easy from seed bought at Wildseed Farms.
Survived Florida Summer and made it through frost in winter. Transplants easy. Individual plants seem leggy and top heavy.

This plant is one of my most favorite wildflower seeds to grow! It does great under other plants in a container, to keep the water from knocking the dirt out every time you water.

Tall winecup, preferably called tall poppy mallow, is an annual that is from 1-3 feet tall. It grows several stems from a small, thin taproot with many fibrous roots which makes it difficult to transplant. It can be found in fields, prairies and woods. It is a native wildflower that is found in Texas as well as other states and blooms in the spring and throughout the summer. The reddish-purple to pink, 5-petaled blooms form a 2 inch in diameter cup-shaped bloom. The alternate, leaves are palmate and lobed. The flowers are quite similar to those of the common winecup (Callirhoe involucrata). It can be distinguished from Callirhoe involucrata by its upright growth habit. Callirhoe involucrata tends to sprawl close to the ground. Callirhoe involucrata flowers have an epicalyx (called involucral bracts in other plant families) which is a whorl of small bracts (modified leaves) found just below the calyx. Tall Poppy Mallow flowers don't have these bracts.
