Gunnera manicata grown from seed by us from our plant (mother plant second picture, early on in the year.)  3ltr pots.  This is a beautiful plant with leaves reaching up to 3m accross. The grandest foliage plant for damp or boggy soil, giving a tropical air to temperate gardens. You may shelter beneath huge parasol-like leaves, held  aloft on wrist-thick, bristly stalks. Curious flower spikes hide beneath, differing from G. tinctoria as they are finger-like rather than club-like. Apply farmyard manure lavishly. Protect coconut-sized resting buds in winter with own foliage bent over, plus bracken or herbaceous remains.  Full sun.
