Arisaema speciosum is a very popular variety. We have grown this one for a number of years and it does look great in a mixed border. You could also try growing them through hosta’s. Grow Arisaema Speciosum in sheltered, shady conditions in soils that remain moisture in the summer months and is free draining. They will produce a purple, pinkish-violet and white spathe on strong erect stems.

Arisaema, also known as Cobra Lilies, are spectacular plants that grow from woodland floors and have unusual flowers. Arisaema will thrive in well-drained, nutrient-rich soil that has with dappled sunshine overhead. Whether you’re planting one or two to as a striking architectural centre piece. Or even if you are planning an extensive grouping, you can be rest assured that these winged cobras will become a focal point in your garden.

Cultivation instructions:

Indoor planting: Not suitable for growing indoors. Can be started off in pots inside and moved or planted outside once you see growth.

Planting outside: Ensure they are planted quite deep as doing this will protect the tubers and rhizomes from frost. Arisaema are happiest in soil conditions that are neutral to slightly acid. Cultivate soils to a depth of 20cms if possible and add plenty of grit and humus matter to the soil. Plant bulbs so that they are 10-15cms below the soil surface.

Can also look great if grown with martagon lilies, hostas or wood anemones.

Remember to mark the position you plant them in as they can easily get lost.
