Shopping for plants online opens up a world of possibilities, but it also comes with a unique set of challenges. When you can’t see the plant in person, you must rely entirely on the product description.

These descriptions are full of terms that can feel like a foreign language if you’re new to gardening.

This guide will break it all down for you. You’ll learn how to decipher plant names, understand care requirements like sun and water, and interpret growth habits.

By the end, you’ll know exactly how to read online plant descriptions like a pro and choose plants that are perfect for your space.

Understanding Plant Names

The first thing you’ll notice on a plant’s product page is its name. Typically, you’ll see two: a common name and a scientific one. Both have their uses.

Common vs. Scientific Names

A plant’s common name is the everyday name you probably know it by, like “Snake Plant” or “Fiddle Leaf Fig.” These are easy to remember, but they can be unreliable.

A single common name might refer to several different plants, or the same plant might have multiple common names depending on where you are.

Scientific names, on the other hand, are universal. Each plant has a unique, two-part Latin name (genus and species) that is recognizable worldwide.

For example, the Snake Plant’s scientific name is Dracaena trifasciata. When you need to be certain you’re buying a specific plant, the scientific name is your best friend.

Cultivar and Variety

Sometimes you’ll see a third part to a plant’s name, which indicates a specific cultivar or variety.

A variety is a naturally occurring variation within a plant species. A cultivar, short for “cultivated variety,” is a plant that has been intentionally bred by humans to have specific traits, like a unique flower color or leaf shape.

For example, Hydrangea macrophylla ‘Endless Summer’ is a popular cultivar of the bigleaf hydrangea. The ‘Endless Summer’ part tells you it’s a special type bred to bloom all season long.

These names signal that a plant has distinct features you might want for your garden.

Decoding Basic Plant Information

Once you figure out the name within an online description, the next section usually covers the plant’s basic needs. These are the must-haves for a plant’s survival.

Hardiness Zones

The USDA Plant Hardiness Zone is a number that tells you the coldest winter temperature a plant can survive. The United States has distinct zones based on average minimum winter temperatures.

If a plant is “hardy to Zone 5,” it can withstand temperatures down to -20°F.

You can easily find your zone by entering your zip code on the USDA website. Matching plants to your hardiness zone is the first step to making sure they’ll survive the winter in your area.

Sun Exposure

How much light a plant gets is just as critical as temperature. Descriptions use specific terms to explain this:

• Full Sun: The plant needs at least six hours of direct, unfiltered sunlight per day.
• Partial Shade/Partial Sun: The plant thrives with three to six hours of sunlight.
• Full Shade: The plant prefers less than three hours of direct sunlight each day.

Giving a plant the wrong amount of sun can cause problems. A shade-lover placed in full sun may get scorched leaves, while a sun-lover stuck in the shade might fail to bloom.

Plant Size

The description will list the plant’s mature height and width. This isn’t the size the plant will be upon arrival, but how large you should expect it to get once it’s fully grown.

Pay close attention to these dimensions. A cute little shrub might look perfect now, but if it grows to ten feet wide, it could quickly overcrowd its spot.

Interpreting Growth Habits

Next, you’ll find information about the plant’s life cycle and how quickly it grows. This helps you manage expectations and plan your garden’s evolution.

Annuals, Biennials, and Perennials

This classification tells you how long a plant lives:

• Annuals complete their entire life cycle—from seed to flower to seed—in a single growing season.
• Biennials have a two-year life cycle. They typically grow leaves in the first year and produce flowers and seeds in the second year.
• Perennials live for three or more years, often dying back to the ground in winter and re-sprouting in the spring.

Knowing this helps you plan. Annuals are great for adding temporary color, while perennials form the long-term foundation of your garden.

Growth Rate

Plants are also described as having a fast, moderate, or slow growth rate.

A fast-growing plant might fill a space quickly, which is great for privacy screens but could also mean more frequent pruning. A slow-growing plant requires patience but typically needs less maintenance over time.

Special Considerations

Finally, the description will detail soil and water preferences. Getting these right is the final piece of the puzzle for a happy plant.

Soil Requirements

Plants can be picky about their soil.

Descriptions might specify a preference for sandy, loamy, or clay soil. They may also mention a need for “well-drained” soil, which means the soil shouldn’t stay waterlogged after rain.

If your native soil isn’t ideal, you can typically amend it with compost or other materials to improve its structure.

Water Needs

Watering is where many new gardeners stumble. Look for terms that describe a plant’s water preferences:

• Drought-tolerant plants can survive with very little water once established.
• Average water needs mean the plant likes consistent moisture but not soggy soil.
• High water needs indicate a plant that thrives in wet conditions.

Match plants to your natural rainfall and your willingness to water. If you tend to forget, a drought-tolerant plant is a forgiving choice.
