Roscoea are hardy perennial bulbs and can tolerate temperatures down to -15C. This means that they can be planted directly outside in the spring in most areas and don’t require winter frost protection.

— Plant directly into a clear, well-dug space in a border between March and May. You can also plant them straight into patio containers.

— Roscoea don’t mind heavy soils with some clay, they can also be planted in rich, free-draining loamy soils. Choose a position which is in full shade or partial shade.

— Plant with the crown facing upwards and tubers pointing downwards, around 5-10cm deep in borders or patio containers.

— Space the bulbs around 10-15cm apart from each other.

— If planting in patio containers, it’s best to use soil-based compost or multipurpose with added loam.

— Water-in after planting and continue to water regularly once in growth in the first year.

— Remove the flower stems after flowering and cut back foliage to ground level in autumn. They bulbs can stay outdoors in their planted positions without any frost protection over winter.
