How to grow King's spear and other Eremurus Plants in the Garden

Eremurus can be planted outdoors from roots or seeds. The roots should be buried at a depth of about 10 to 15 cm, whereas seeds should be lightly covered and planted in flats beneath glass; both should be planted in the autumn. They prefer to grow in a sunny area of the garden and thrive in a well manured peaty soil.

If you plan to start Eremurus plant species such as King's spear and Desert Candle indoors first, then they should be planted into a flat within a black bag, then placed in the fridge for three weeks.

Seeds should then be grown at a temperature of 12 to 15 Celsius; they normally take from one to twelve months to germinate.

The flats should then be placed outdoors north facing, once seedlings emerge remove the glass and transplant to their final location in the Autumn. Propagate the plants by division.
