I would appreciate any info you can give me on planting, caring for four o'clocks, such as most common colors, what they look like, how big they get.

Mirabilis jalapa flowers in shades of yellow, red, white, and pink from summer to fall. It takes full sun, average soil, and grows from 2-4 feet tall. Seeds are sown outdoors in spring and germinate in 10-14 days. They are called four o'clocks because the flowers usually open in late afternoon. Flowers are 2 inches long and trumpet shaped and may stay open all day on cloudy days. The plant can reseed itself and may be perennial in mild climates. It's roots are tuberous and may be dug up and stored like dahlias.

All parts of the plant are poisonous. I hope this info helps!
