Unique CharacteristicsDeep purple grape-like berries

Native to North America, Pokeweeds are known for their longevity and adaptability. They’re herbaceous perennial plants that thrive in warm, hot climates.

Aside from that, they can withstand various humidity conditions, live in virtually any soil type, and varying sun exposures.

Because of this, they’re widely considered invasive plants as they tend to overwhelm native flora, especially when not planted on purpose.

Even with their shrub-like appearance, they can grow to up to 12 ft in height and 6 ft in width. Meanwhile, their leaves grow into a heart shape of about 6 to 12 inches long.

In the summertime, they produce white flowers and clustered grape-like berries. As they ripen, the berries turn from a vibrant green to a deep purple color.

Be warned, though, that these berries are poisonous to humans and most animals. Even then, there are a few species of birds that are immune to the toxins.

It’s also important to note that the older your Pokeweed plant gets, the more toxic it becomes. Hence, if you’d like to eat the pokeberries, you may want to grow a new plant annually.

While their leaves are also known to cause allergic reactions, there are some who’ve turned this into a delicacy. The leaves and young shoots are cooked into a salad known as the ‘poke sallet’.

The wineberry prefers humid and moist environments that receive about full to moderate shade. Despite being a dense bush, its stalks grow to about 10 feet high.

It’s pretty unique that its heart-shaped leaves sprout in threes. The topside has a vein-like pattern, which kind of resembles a poison ivy leaf while its underside has a tinge of silver.

As for its bright red berries, they look just as sweet and juicy as they taste. So, don’t be surprised if you see songbirds and similar small mammals munching on these fruits in the wild.

Even then, the wineberry is still considered an invasive species in areas where they don’t have any natural predators.

While bears a resemblance to blackberries and raspberries, the wineberry is actually less flavorful and contains more seeds. It may also not be the best option for baking as it has a higher water content, which can put off your recipe if not adjusted.

FAQs about plants with red stems

What causes a plant to have red stems?

There are several kinds of plants that have naturally reddish stems. Most herbaceous plants contain a pigment called ‘anthocyanins’ that’s responsible for giving them a red color.
Otherwise, a change in color may be caused by extreme changes in weather, temperatures, light, and excessive stress.

Do plants with red stems and leaves require more sunlight?

Red plants require more sunlight as their anthocyanins often cover their chlorophyll, reducing the quantity available to properly photosynthesize.

What stressors can cause a plant’s stem to turn red?

All stressors such as overwatering, underwatering, extreme temperatures, and pest infestations, among others, can cause your plant’s stem to turn red.

What kind of nutrient deficiencies can cause a plant’s stem to turn red?

Stems turning red is a result of inadequate amounts of magnesium and phosphorus in the soil. This can easily be remedied by correcting the soil’s pH levels.
