Certified Professional Horticulturist (CPH) Practice Exam

By law, nursery tags must have this information on them:

1. Scientific name, plant care, spacing

2. Scientific name, common name, price

3. Common name, spacing, price

4. Scientific name, height/caliper, price

The correct answer is: Scientific name, height/caliper, price

The requirement for nursery tags is primarily to provide essential information that helps consumers make informed decisions about the plants they purchase. The correct choice includes the scientific name, which is crucial for identifying the plant accurately. This is important because many plants can have common names that vary by region, leading to confusion in plant identification. Additionally, including height or caliper gives potential buyers an understanding of the plant's size, which is crucial for planning in landscaping and ensuring that the plant fits the available space and meets aesthetic expectations. Pricing, while not always legally required on tags, is generally included to inform customers about the cost of the plant. The other options fail to include the comprehensive combination of scientific identification and size specifications that would provide the most relevant information for consumers and allow them to gauge the plant's requirements and suitability for their environment. Therefore, the option that incorporates the scientific name, height or caliper, and price gives a complete picture of what the consumer needs to know when considering a plant purchase.
