Stout stems hold heavy heads of bright blue flowers over clumps of green strap-like leaves which arise from slowly enlarging bulbs. This lovely, easily grown, very long lived and exceptionally large-flowered plant does not come from Peru. When the original bulbs were imported from Spain in the 17 century the ship they travelled on was "The Peru"!
Sow seeds at any time covering them with compost or grit 5mm deep, keeping the seed pot in a cool, well-lit spot outdoors. Artificial heat is not needed and can prevent germination so be very patient as many species will only germinate in the spring after chilling or freezing in the moist seed tray in the winter. Grow on individual seedlings in small pots until of sufficient size to be potted on or planted out into the open ground.
