Quick Grow Facts

• Plant Type: Cool-season annual bedding plant
• Scientific Name: Nemesia strumosa
• Variety: Carnival Mix; individual seedling colours vary
• Seed Form: Raw seed
• South African Sowing Time: Autumn in mild and winter-rainfall districts; protected late winter for frost-prone spring gardens
• Position: Full sun in cool weather; morning sun and light afternoon shade as temperatures rise
• Sow Depth and Light: Sow onto moist, finely prepared seed mix and cover lightly. Keep the mix evenly moist, not soggy; give seedlings bright light after emergence.
• Germination: Sow at about 15°C and maintain even moisture; emergence varies with growing conditions
• Moisture: Keep the fine surface continuously moist but never saturated
• Pretreatment: None; do not soak, chill or scarify
• Transplanting: Move a root-held plug with several true leaves; harden for 5–7 days
• Spacing: Allow room for the mature clump and good airflow, widening spacing in humid gardens
• Growth Form: Compact to semi-dwarf; about 25 cm high; no support needed
• Pinching: Optional light tip pinching on a leggy plant may encourage branching and delay bloom; correct weak light or excess warmth first and skip naturally compact plants
• Flowering: Flowering time varies with growing conditions; deadhead or lightly shear spent stems while weather stays cool
• Use and Safety: Ornamental only; treatment status is not confirmed, so do not eat the seed

Why Grow This Variety

• Large mixed-colour flowers make a cheerful cool-season display.
• The compact size suits pots, low borders, edging and grouped planting.
• Raw seed is practical for sowing larger drifts.
• Light trimming after a flush can encourage more flowers if cool weather remains.

Garden Uses

Use Carnival Mix in a free-draining container, at the front of a cool-season border or as dense edging. Each seedling produces its own colour or pattern, so a small sample may not contain every colour shown.

Growing Notes

• Apply a light covering of fine seed mix and maintain even moisture; avoid a heavy covering.
• Use clean, fine seedling mix and water from below or with a gentle mist.
• Keep seedlings bright, cool and airy after emergence to prevent stretching and damping-off.
• Water regularly but let surplus drain; sustained heat and waterlogged roots shorten the display.
