Balcony Volunteer Identified as Nasturtium

A plant sprouted in balcony flower pots in Graz, Austria after a two-week absence. Expert identifies it as likely nasturtium (Tropaeolum majus).

Confirmation

Compare to nasturtium images online – distinctive round leaves and eventual bright flowers. Nasturtiums self-seed readily and grow quickly.

Care

• Full sun to part shade.
• Poor to average soil – rich soil reduces flowering.
• Edible flowers and leaves (peppery flavor).
• Annual in cool climates; may reseed.

Flower structure confirms ID – wait for blooms if unsure.
