This must be the most majestic herbaceous plant which is hardy in this country. With leaves that can grow to 6 foot across, supported on stout, prickly stalks up to 8 foot long, this plant resembles a giant rhubarb! Bears thousands of minute reddish flowers on club-shaped spikes up to 6 foot tall. A fantastic architectural plant which is particularly happy in moist ground.

Hardy Perennial
Height: up to 3m
Position: Sun or semi-shade - particularly happy in moist ground.

Packet of 30 seeds



Sowing Instructions: Sow at any time of year. Sow thinly at a depth of 1.5mm in pots or trays of moist seed compost. Place in a propagator or seal in a polythene bag and maintain a temperature of 25-27C with good humidity. Germination can be erratic and slow and can take several months. Keep the seed compost very moist, but never saturated at all times and the temperature high. 

Growing Instructions: When seedlings are large enough to handle, pot up individually into 7.5cm pots and grow on in a greenhouse or coldframe, overwintering frost-free as necessary. When well established, plant out in spring when all risk of frost has passed, 90cm apart in moist, loamy soil and part shade.
