Gladiolus Flevo Nautica is a beautiful summer-flowering variety that adds a touch of elegance to home gardens, flower beds and cut-flower arrangements. Its striking flower spikes carry multiple large, funnel-shaped blooms that open gradually from the bottom upwards, creating a lovely display over the flowering season. The flowers are soft lilac to light purple, with deeper lilac-purple edges and a pale throat, sometimes showing a subtle pinkish-maroon shade towards the centre. The petals spread out gently, giving each bloom an elegant, open appearance. This variety grows tall, with upright stems and long, sword-shaped green leaves that provide a lovely contrast to its pastel flowers. Gladiolus Flevo Nautica is an excellent choice for gardeners who enjoy growing their own cut flowers, as its long stems work beautifully in vases and floral arrangements. Plant the bulbs in a sunny spot with fertile, well-drained soil to encourage healthy growth and flowering. With the right care, these bulbs can bring height, colour and a graceful look to your garden during the warmer months.
Growing guide for Gladiolus Flevo Nautica Bulbs
Planting instructions
Prepare the soil by loosening it to a depth of about 25–30 cm and mixing in well-rotted compost. Plant the bulbs, also called corms, pointed side up, about 10–15 cm deep in the ground and 10–15 cm apart. For containers, use a pot at least 35–40 cm deep and 30–35 cm wide, with drainage holes.
Growing Requirements
Pests
Gladiolus may be affected by thrips, aphids, slugs and snails. Avoid overwatering and poor drainage to prevent bulb rot and fungal diseases, and remove affected leaves promptly.
soil
Gladiolus grows best in fertile, loose, well-drained sandy loam soil rich in organic matter. A slightly acidic to neutral soil with a pH of around 5.5–7.0 is suitable for healthy growth.
spot
Choose a sunny, sheltered spot that receives at least 6–8 hours of direct sunlight daily. A flower bed, garden border or spacious sunny patio is ideal, as the tall flower spikes may need support against strong winds.
temperature
A temperature range of around 15–25°C is suitable for healthy growth and flowering. Protect the bulbs from frost and avoid prolonged exposure to extreme heat, especially when the plants are young.
watering
Water thoroughly after planting and keep the soil evenly moist during active growth. Water when the top layer of soil begins to dry, avoiding waterlogging, which can cause the bulbs to rot.
how to harvest
Cut the flower spike when the first one or two flowers at the bottom begin to open, preferably during the cooler hours of the day. Use clean, sharp scissors and place the stems in fresh water immediately to help keep the flowers looking fresh for longer.
