Delivered to you from April
The biggest and tallest flowering form with yellow-green flowers held some way off the stem so that the whole flower head is more impressive. Late flowering and supplied as big bulbs from our own stock that will need deep planting to provide some support for the thick stem. We regard them as perfectly hardy though a long way north the summer may be too short to get the full benefit of them.
Huge bulbs to plant deeply in full sun and with 5-6" (12-15cm) of soil covering the bulb to aid support of the stem and 20"(50cm) apart or in big well watered pots. Allow 2' (60cm) spread.
Height 4-5' (120-150cm)
