Description

No wonder this is also called Tower of Jewels or 'Pride of Tenerife! Exceptionally tall flower spikes packed with either rose or purple-blue flowers, interspersed with silver-green lanceolate leaves.

Sowing Instructions

Sow 3mm (1/8in) deep in good seed sowing compost from late May-late July. Germination takes 7-14 days at 18-20C (65-70F).

Aftercare

Although this species is proving to be quite cold hardy, its best to cover the base of the plants with a little bracken or similar over the winter. They can also be grown in 30cm (12in) pots to flower in a conservatory or cool greenhouse.
