Nasturtium Flower Labels: A Seasonal Record for Better Harvests

Nasturtium flowers are at their best in a narrow window: buds opening, petals unwrinkled, and the peppery flavour still sharp. Home growers who pick a handful for a salad often lose track of which plants performed, which flower colour tasted best, and when the flush peaked. A small, deliberate labelling and record system turns that scattered observation into a seasonal opportunity you can plan around next year. Labels do not merely name a plant; they anchor a harvest date, a flavour note and a repeatable decision.

Why nasturtiums deserve their own records

Tropaeolum majus and its close garden relatives are grown for flowers, leaves, buds and seed pods, all eaten fresh. That range of edible parts makes memory unreliable: the day you pick flowers is not the day the buds are best for pickling, and the pods that follow are a later crop again. A label tied to a bed or pot can carry a date and a short kitchen note, so each harvest becomes evidence rather than a vague impression.

Flower colour also affects what you notice in the kitchen. Yellow and orange cultivars look different scattered over a green salad, and some gardeners find one colour reads better on a plate. Record the cultivar name where known, or at least the colour, because open-pollinated nasturtiums vary. Without a note, a particularly good-tasting or long-flowering plant is lost by the following season.

Choosing a labelling method that survives the garden

The right label is the one that stays legible through watering, sun and soil splash. There are three broad choices, and each suits a different scale of growing.

• Wooden or bamboo plant tags are cheap, natural-looking and easy to write on with pencil. They weather within a season and suit annual nasturtiums that are replanted each year.
• Plastic or metal stake labels last longer and take waterproof marker or pencil, but a durable label is wasted if the writing fades. Choose a marker intended for outdoor use and test it on one label before committing your whole bed.
• Copper or aluminium write-on tags cost more per label and suit records you want to keep across seasons, such as a named cultivar you intend to save seed from.

Whatever the label, keep it at the base of the plant, not at the edge of a mixed bed. Nasturtiums sprawl; a label marking the crown tells you where the plant actually began and helps you judge how far it has run.

What to write on the label and in the notebook

A label is a short, visible reminder. The full record belongs in a notebook or on a simple spreadsheet, where there is room for harvest notes. A practical split:

On the label

• The plant name, or cultivar and colour if you know it
• The sowing or planting date
• A short code or bed letter that links the label to your longer record

In the seasonal record

• First flower opening and peak flowering week
• First harvest of flowers, leaves, buds and green seed pods, as separate dates
• A one-line flavour note: hot, mild, sweet, bitter, or good on a particular dish
• Whether the plant stayed productive or declined, and when you pulled it
• Any seed saved, with the label code and a note on the parent plant

Write the harvest note the same day. A flower picked and eaten at lunch is easy to describe at dinner and hard to remember a week later. Even a brief entry, such as "orange, hot, good with cucumber," is enough to guide next year's choices.

Identifying the seasonal opportunity

Nasturtiums reward a little forward planning because their edible stages follow in sequence. Rather than treating the plant as one crop, use your record to spot the window that matters to you.

If your priority is fresh flowers on the table, the record should show when flowering begins and how many weeks it stays generous. A cultivar that starts early but fades after two weeks is a different garden plant from one that flowers later but steadily. You can then sow at intervals, or choose a later-flowering cultivar, so that flowers reach the kitchen across a longer period.

If your priority is buds or green seed pods, your record should capture the weeks between flowering and pod set. Green pods are picked young, while still firm and bright, and used in the same way as capers. Tracking the harvest dates shows you when that stage is reliably reached in your own garden, which is more useful than any general calendar. Note, too, that flower colour and pod yield are not linked in any fixed way; your own record is the guide.

Leaves are a third opportunity. They are milder than flowers and can be harvested from healthy plants through the season. A record of leaf harvest, and of when the plants became tough or pest-damaged, tells you when the leaf crop stops being worth picking.

Turning notes into next year's plan

At the end of the season, read the record back and ask three questions. Which stage gave the best kitchen value: flowers, buds, pods or leaves? Which plant, by cultivar or colour, stayed productive longest? And when did the first useful harvest arrive, relative to when you sowed? The answers decide the next sow: earlier or later, more plants of one colour, or a succession of sowings to spread the harvest.

Keep the labels from named plants you intend to save seed from. Nasturtiums are easy to save because the seed is large and the plants self-pollinate readily, though garden varieties in a mixed bed will cross. Label the parent plant and keep its seed separate, with the colour and date noted. A saved seed crop extends the record across seasons and gives you a named line to compare against newcomers.

Kitchen handling that protects the record's value

A good harvest note is worthless if the kitchen handling spoils the crop. Pick nasturtium flowers in the cool of the morning, when petals are firm, and use them the same day. Rinse briefly in cool water only if there is visible soil or grit; delicate petals bruise easily. Leaves and young pods tolerate a firmer wash and can be dried on a clean cloth.

Flowers and leaves are eaten fresh, not stored for long. Keep picked flowers cool and loosely covered, and discard any that have wilted or gone slimy. Buds and green pods are better used fresh or preserved by a tested recipe rather than improvised. If your aim is to keep pods beyond the fresh harvest, follow a reliable tested pickling or brining method; the record of harvest date still tells you which pods were picked when.

Nasturtium is a useful edible plant for the home garden because it earned its place not only by looking good but by providing several harvests from one sowing. A label and a short seasonal record make those harvests visible and repeatable. The result is a more deliberate kitchen garden, one where the best-performing colour, the earliest flowering time and the tastiest pod season are known rather than guessed.
