How to plant Dicentra / Lamprocapnos

Dicentra (new official name: Lamprocapnos) are full hardy down to around -15C and can be planted directly outside in the spring. They will not require winter protection in most areas.

— Soak the roots in water for 3-6 hours prior to planting out

— You can give your plants a good start by plant the bare roots into temporary pots in spring and grow-on in a sheltered spot outdoors to plant out as potted plants later in the season once established. Alternatively, you can plant them and mark them in a clear space directly into borders.

— Plant the roots so that they are fully submerged with the buds or crown just below the surface and any top growth or leaves exposed.

— Choose a position in partial or full shade for your Dicentra.

— Space the plants 20-30cm apart

— Water-in after planting and keep hydrated when in growth

— Cut back foliage and stems to 3cm above soil level in the autumn.
