Rhubarb sparks much interest in gardeners once they come across look-alike plants in their yards. The confusion arises from plants that have similar stems and leaves.

While it’s true that these plants exist, it doesn’t mean they are in the same family or carry the same characteristics as the original plant. More astounding is that historically, other plants have been called Rhubarb.

The origin of the plant is still uncertain, but apart from it being edible, it also has medicinal properties that could be harnessed in the future.

Without further ado, let’s deep dive into the list of plants that look like Rhubarb. We will first take an in-depth look at the latter.

What Does Rhubarb Look Like?

Rhubarb is a herbaceous perennial found in the Rheum species and hybrids;  it also belongs to the family Polygonaceae.

It establishes itself via short, thick rhizomes. Gardeners find the fleshy and edible stalks of the Rhubarb a fantastic culinary addition.

This is typical in the US and Europe. However, it’s majorly used for medicinal purposes in Asia.

Their large triangular leaves are inedible because of the high levels of oxalic acid and other compounds such as the throne glycosides.

Rhubarb has tiny flowers that group to form large leafy rose-red or greenish-white inflorescences. Fundamentally, gardeners consider the plant a vegetable, but it also serves the culinary use of fruit.

Their stalks come in various colors, majorly appearing red or pink. Rhubarb dish has a sour taste, and most gardeners commonly prepare it with sugar and incorporate it in desserts.

Rhubarb thrives best in cooler temperatures below 5 degrees celsius. It breaks dormancy around spring when fast growth is stimulated.

It does well in summer temperatures averaging less than 23 degrees celsius, which helps to promote vegetative growth.

There are many Rhubarb varieties, but the most common is edible Garden Rhubarb.

Growing Rhubarb In Your Garden

Rhubarb grows in moist, fertile, well-drained soils rich in organic matter. Thorough soil preparation is of essence to ensure a bountiful harvest.

Rhubarb loves slightly acidic to neutral soils. One square of yard space is enough for each plant.

  • Keep your bed clean by clearing it of problematic perennial weeds.
  • Loosen the soil to 10 inches and add well-rotted manure to about 3-4 inches.
  • When planting, maintain a soil cover of 1-2 inches on the crowns.
  • Press the soil firmly around the base to get rid of air pockets.
  • Apply a fertilizer that is rich in Potassium and Phosphorous.

Deep planting delays production. Once your Rhubarb starts growing up, add straw mulch to help control weeds and maintain soil moisture.

Get rid of flower stalks as soon as they appear since they deplete the reserves that promote vegetative growth. Apply a light sprinkling fertilizer each spring.
