Nasturtium Golden Globe - 5 Seeds

Nasturtium 'Golden Globe' (Tropaeolum majus) is a compact, bushy, and mounding variety that produces bright golden-yellow flowers with a soft, velvety texture. The flowers contrast beautifully against the round, green leaves, creating a vibrant display in gardens, borders, and containers.

This dwarf nasturtium variety grows to about 30–40 cm tall and 40–50 cm wide, making it perfect for small gardens, pots, hanging baskets, and pathway edges. It is an easy-to-grow annual, thriving even in poor soil and dry conditions, and is well-loved for its edible flowers and leaves, which have a distinct peppery flavour.

In addition to its ornamental value, 'Golden Globe' is a beneficial companion plant that helps repel pests like aphids, whiteflies, and cucumber beetles.

 

Growing Guide

Soil Requirements

Prefers well-drained, moderately fertile, or poor soil.

Avoid rich soil, as it encourages excessive leafy growth and fewer flowers.

Ideal soil pH: 6.0–7.5 (neutral to slightly acidic).

If growing in containers, use a lightweight potting mix with good drainage.

Sunlight & Location

Thrives in full sun (at least 6–8 hours per day).

Can tolerate partial shade, but this may reduce the number of flowers.

Suitable for flower beds, borders, rock gardens, containers, and hanging baskets.

Can withstand coastal conditions and poor soil, making it a hardy choice for various environments.

Planting & Germination

Starting from Seeds (Indoors & Outdoors)

Indoor Sowing:

Start 2–4 weeks before the last frost in biodegradable pots (nasturtiums dislike root disturbance).

Sow seeds 1–2 cm deep in well-draining potting soil.

Maintain a temperature of 18–22°C for best germination.

Germination occurs within 7–14 days.

Transplant outdoors once seedlings are 10 cm tall and all frost danger has passed.

Direct Sowing (Preferred Method):

When: Sow seeds directly after the last frost when soil temperatures reach 10–15°C.

Spacing: Plant seeds 20–30 cm apart to allow for proper air circulation.

Depth: Sow 1–2 cm deep, covering lightly with soil.

Keep soil evenly moist until seedlings emerge.

Watering

Water moderately—nasturtiums prefer slightly dry conditions once established.

Avoid overwatering, as it may lead to root rot or fungal issues.

Water early in the morning or evening to prevent rapid evaporation in hot weather.

Fertilization

Minimal fertilization is needed.

Avoid high-nitrogen fertilizers, which will promote leaves at the expense of flowers.

If necessary, apply a low-nitrogen, phosphorus-rich fertilizer once during early growth.

Maintenance & Pruning

Deadhead spent flowers regularly to extend blooming.

If plants become leggy, trim back by a few centimetres to encourage bushier growth.

Nasturtiums self-seed, meaning they may return in the following season if flowers are left to mature.

Pest & Disease Control

Natural Pest Repellent: Nasturtiums attract aphids, making them a sacrificial plant to protect nearby vegetables.

Companion Planting: Helps repel whiteflies, squash bugs, and cucumber beetles.

Diseases: Generally, disease-resistant but can be affected by powdery mildew in humid conditions—ensure proper air circulation and avoid overhead watering.

Harvesting (Edible Flowers, Leaves & Seeds)

Leaves & Flowers:

Can be harvested fresh for salads, sandwiches, and garnishes.

Flowers add a spicy, peppery flavour, similar to arugula.

Seed Pods:

Young, green seed pods can be pickled and used like capers.

Mature seeds can be dried and collected for planting next season.
