Zantedeschia Red Alert

(inc. 20.0% VAT)



An intense, vivid red to stop passers-by in their tracks, Zantedeschia ‘Red Alert’ is no shrinking violet. The showstopping, scarlet spathes envelop a glowing orange spadix, sitting proudly atop decorative, dark green, white speckled leaves. This bold, architectural variety is especially well-suited to patio displays, tropical planting schemes and modern designs. ‘Red Alert’ relishes moist, rich, well-drained soil, position in a sheltered, lightly shaded location. Beloved by florists, the fiery, funnel-shaped flowers make a bright focal point in floral arrangements and bouquets, lasting over a week in the vase.

Care Guide

Most varieties of Zantedeschia grow best in a conservatory or greenhouse in sun or part shade. 

Plant rhizomes 8-10cm deep in a container filled with good quality, free-draining multi-purpose compost.  Provide consistent watering, ensuring the soil stays moderately moist to maintain lush growth of your calla lilies.

Plants can be gradually hardened off in late spring and enjoyed outdoors in a sunny spot for the warm summer months.

Once flowers start to appear, feed plants every 3 weeks with high-potash liquid fertiliser.

These frost-tender perennials must be brought back indoors before temperatures drop in autumn and protected from freezing temperatures.

Zantedeschia Aethiopica is the only fully hardy member of the family which may be grown outdoors all year round
