Q: Do you know the name of this plant and flower?

Q: I bought some seeds from Amazon that were supposed to be straw flowers. When I planted them in the spring, this is what appeared. I don’t think the plant is a straw flower. Can you help me identify this plant?

A: Both Becky and Jeannie have pokeweed.
“The purple fruits are pokeweed – like ‘poke salad Annie’ in the song,” said Ellen Zagory, public horticulture director at the UC Davis Arboretum. “Phytolacca americana is a weed here, but native in the southeast United States where it is sometimes eaten.”
Think twice before adding any of those greens to a salad. All of this plant is poisonous. In particular, those pretty purple berries can be deadly, especially to pets or small children.
“It’s extremely poisonous and needs special preparation to remove toxins,” Zagory said.
Pokeweed can reach 10 feet tall with leaves 12 inches long. It blooms in summer, producing these colorful (and dangerously tempting) berries in July and August. The berry clusters often are more than 10 inches long.
Pokeweed is a perennial, which means – once it’s established – it will grow back from the roots year after year. To eliminate this plant from your garden, you need to dig out the roots.
But remember to wear gloves while handling any part of this plant. It’s toxic through and through.
As for the other mystery plant, it’s much more benign.
“The red-pink thing is a crested form of Celosia or cockscomb, an annual grown for its showy flowers,” Zagory said.
Celosia, a member of the amaranth family, has become a popular cut flower, too. The blooms, which come in several bright colors, can last up to 10 weeks on the plant and many days in a vase.
