**Facilitating Seed Sharing and Trading:When sharing or trading seeds with other gardeners, accurate labeling is crucial for providing them with the information they need to grow the plants successfully. Clear labels build trust and ensure that your seeds are properly appreciated.
**Avoiding Unexpected Results:Imagine planting what you thought were your prized sweet peppers, only to discover they're fiery hot chilies! Accurate labeling prevents these kinds of disappointing surprises and ensures you're growing exactly what you intend.

Essential Information to Include on Your Seed Labels

What information should you include on your seed labels to ensure accuracy and clarity? Here’s a comprehensive list of essential details:

**Variety Name:The most important piece of information! Be specific and use the full variety name (e.g., ‘Brandywine Pink' tomato, not just ‘Brandywine').
**Species:Include the scientific name (e.g., *Solanum lycopersicumfor tomato) if you’re saving a diversity of plants from the same family.
**Source:Note where you obtained the seeds – whether you saved them yourself, received them from a friend, or purchased them from a particular seed company. This can be helpful for tracking the origin and quality of your seeds.
**Date of Harvest:Record the date you harvested the seeds. This information is crucial for determining seed viability, as germination rates tend to decline over time.
**Planting Date (Optional):The date you plan to plant the seeds can be useful for organizing your seed collection and planning your garden.
**Generation (Optional but Recommended):If you're saving seeds from plants you've grown yourself, note the generation (e.g., F2, F3). This indicates how many generations the seeds have been saved and can provide insights into their genetic stability.
**Growing Notes (Optional):Include any relevant observations about the parent plant, such as its size, yield, disease resistance, or flavor.

Descriptive Examples

Here are some examples of well-detailed seed labels:

**Tomato, ‘San Marzano', *Solanum lycopersicum*, saved from garden, harvested 09/15/2023, F2. High yield, excellent flavor.**
