Preparing for the NC Certified Plant Professional (CPP) exam can feel overwhelming at first, especially when you begin working through the required plant list and the breadth of horticultural knowledge covered across 17 chapters. Many candidates discover that memorizing plant names alone is not enough. Success on the exam depends on understanding key concepts across plant biology, landscape design, pest management, pruning, and more — while also being able to recognize plants quickly and confidently (Fair, 2015).
The CPP exam covers a wide range of topics, from the green industry in North Carolina to nursery production practices. The official study guide organizes this content into 17 chapters, each with specific study objectives that tell you exactly what the exam expects you to know (Fair, 2015). This article walks you through every chapter with those study objectives so you can build a focused, effective study plan.

How the Plant ID Portion Works
The plant identification portion of the CPP exam is a separate component from the written multiple choice section. Understanding the format before exam day will save you time and reduce confusion.
The Format, Step by Step
- You receive a photo booklet containing numbered photographs of plants from the CPP plant list. Each photo is assigned a number (Photo #1, Photo #2, and so on).
- You also receive the official NC CPP Plant ID List, which lists all 267 plants organized by category — annuals/perennials, shrubs, trees, vines, diseases, insects, and weeds — each assigned a number.
- Your job is to match each photo to its correct plant on the list. On your answer sheet, you write the plant list number that corresponds to each photo. For example, if Photo #1 shows trailing sedum, you would write 64 on your answer sheet — because Sedum spp. is number 64 on the plant ID list.
- You are identifying plants by number, not by writing out names. This means you need to be deeply familiar with the plant list numbering, not just the plant names themselves.
This format rewards candidates who have spent time with real images and can recognize plants quickly. Simply memorizing botanical names from a list is not enough — you need to be able to connect a photograph to the correct numbered entry under time pressure. The list includes not only ornamental plants but also common landscape diseases, insects, and weeds, all of which may appear in the photo booklet.
Download and print the official NC CPP Plant ID List and keep it alongside your study materials. Becoming familiar with the numbering system before the exam is a significant advantage.

What to Expect on the Multiple Choice Section
The written portion of the CPP exam is multiple choice and covers a broad range of applied horticulture knowledge. Questions are drawn from across all 17 chapters of the study guide, but several topic areas come up consistently. The following are representative of the kinds of questions that appear on the exam, based on candidate experience.
Topics You Should Be Ready For
- The preferred soil pH range for common turfgrass species used in North Carolina lawns
- The bloom time of sasanqua camellias compared to other camellia types
- The blooming order of commonly used landscape shrubs and trees across seasons
- The mature height and spread of specific shrubs and trees on the CPP plant list
- The correct name of the nursery industry grading manual used for plant standards
- The continuing education credit requirements for commercial pesticide applicators licensed in lawn and ornamentals
- Plant selection for sites defined by sun exposure and cardinal direction — for example, choosing appropriate plants for a sloped, south-facing, full-sun area
- The cause of interveinal chlorosis in landscape plants
Example Questions
The following examples are representative of the multiple choice format. Answer choices on the actual exam will vary.
When do sasanqua camellias (Camellia sasanqua) typically bloom in North Carolina?
- Late winter to early spring, before leaves emerge
- Midsummer, June through August
- Fall, typically October through December
- Early spring, concurrent with forsythia
This question tests your knowledge of bloom timing for specific species on the CPP plant list. Knowing when plants flower — and how that timing compares to other species — is a recurring exam topic.
A client notices that the leaves on their gardenia have yellowing between the veins while the veins themselves remain green. This symptom is most likely caused by a deficiency of which nutrient?
- Nitrogen
- Phosphorus
- Iron or manganese
- Calcium
Interveinal chlorosis — yellowing between leaf veins with veins staying green — is a classic symptom of iron or manganese deficiency, often triggered by high soil pH limiting micronutrient availability. This topic is covered in Chapter 10.
For the remaining topics on the list above — such as nursery stock standards, pesticide license credit hours, turfgrass pH, and plant sizing — expect straightforward factual questions with four answer choices. Studying the chapter content alongside the study guide will prepare you for these.
Understanding the CPP Plant List
The CPP exam includes a plant identification component covering commonly used landscape plants in North Carolina. The list typically includes trees, shrubs, groundcovers, vines, grasses, and perennials frequently encountered in nursery and landscape settings. Candidates are expected to know plants by both botanical and common name (Fair, 2015).
Many candidates find botanical names challenging at first, but repeated exposure makes them easier to remember. Breaking the list into smaller sections prevents burnout and makes the process more manageable. Focusing on plant characteristics rather than memorizing names alone greatly improves retention. Pay attention to traits such as:
Learning these features will make plant identification faster and more reliable on exam day.
Use Visual Study Methods
Plant identification is a visual skill. Reading lists of plant names is rarely effective on its own. Most successful candidates spend time studying clear plant images and practicing identification repeatedly. Visual study tools help reinforce recognition and improve recall — seeing the same plant multiple times from different angles strengthens memory and builds confidence.
Interactive study methods such as quizzes and flashcards are particularly effective because they require active participation instead of passive reading.

Create a Realistic Study Schedule
Consistency matters more than intensity when preparing for the exam. Short study sessions several times per week are more effective than long sessions done infrequently. A practical approach might include studying 10–15 plants per week, reviewing previous plants weekly, taking practice quizzes regularly, and visiting nurseries or landscapes to see plants in person.
Spreading study sessions over several months allows time for repetition, which is essential for long-term memory. Many candidates find that a 60–90 day study period works well for mastering both the plant list and the chapter content.
Study Plants in Groups
Grouping plants by category can make the material easier to learn. Studying similar plants together helps you notice differences and avoid confusion. Useful groupings include broadleaf evergreens, deciduous shrubs, shade trees, ornamental trees, perennials, grasses and grass-like plants, and groundcovers. Comparing similar species side by side strengthens identification skills and improves exam performance.
Practice Active Recall
Active recall is one of the most effective study methods. Instead of simply reading plant names, test yourself regularly. Try covering plant names and identifying them from images. After answering, check your results and review any mistakes. Repeated testing helps strengthen memory and identify weak areas.
Interactive quizzes are especially helpful because they simulate the mental process required during the exam. Try the free flashcard demo to experience how active recall works, then access the full plant identification study materials when you're ready to dive in.
Study Plants in Real Landscapes
Seeing plants in person reinforces what you learn from study materials. Visiting garden centers, botanical gardens, and neighborhood landscapes helps connect plant names to real plants. Try to identify plants without looking at labels first, then confirm your identification afterward. This process builds confidence and strengthens memory. Even short visits to nurseries can significantly improve recognition skills.
Common Mistakes to Avoid
Many candidates struggle because they rely on ineffective study methods. Watch out for these common pitfalls:
- Trying to memorize the entire plant list at once
- Studying only botanical names without images
- Waiting until the last minute to begin studying
- Not reviewing plants regularly
- Avoiding quizzes or self-testing
- Skipping the chapter content and focusing only on the plant list
- Ignoring the study tips provided in the study guide
A structured approach with repeated practice produces better results.
Building Confidence Before the Exam
Confidence comes from repetition and familiarity. The more often you review plants and chapter material, the easier identification and recall become. Most candidates notice that recognition improves quickly after a few weeks of consistent study. Working through the plant list systematically and testing yourself regularly helps ensure you are prepared on exam day.
