Helenium 'Waldstrand Copper'

A tall, herbaceous perennial that grows up to 1m tall.

Coppery-orange daisy like flowers bloom throughout summer on long stems. Long lanceolate green leaves are produced along the length of the stems.

Prefers full sun with well draining soil.

With suitable preparation and care, perennials will grow and flower well year after year. Young plants are easier to establish than larger ones. They will grow quickly when planted in autumn when soil is moist and warm. Always choose healthy, well-grown plants and plant after autumn rains. On heavy soils, raise the level of beds and borders with extra topsoil and coarse pumice sand. Before planting, ensure the root ball is saturated and remove the planter pot with minimal root disturbance. Trim any broken roots and plant at the same level as in the container. Dig a hole twice the diameter of the root ball, press in and water once planted. Make sure plants are watered well until established if planting in a drier period. Plant with some general slow-release fertiliser and then every spring, apply organic fertiliser at a handful per square metre (e.g. blood and bone).

Planting too closely leads to spindly growth, poor flowering and eventual decline. In a well-planned border, flowering plants should just touch each other to create a full effect without overcrowding.

Apply mulch annually to suppress weeds and conserve moisture. Organic material, such as sawdust and bark, contribute to soil structure. However, make sure to keep mulch away from plant stems. The first summer and autumn after planting are critical for young plants, so water thoroughly during dry periods. A light application (50g/m2) of general-purpose fertiliser in spring is beneficial. Sprinkle evenly and work into the top 2 to 3cm of the soil, taking care not to damage the delicate roots.

Dividing is a great way to rejuvenate and get more plants. In autumn, large plants can be lifted and divided. This can be achieved by placing two garden forks back-to-back in the middle of the lifted plant and then pushing the clump apart. In some case, the plant may be able to be pulled apart by hand. Plants need to be divided every 2 to 3 years. If they aren't, they will eventually lose vigour and not produce many flowers. Clumps can be separated to around 10cm in diameter if necessary.

This plant may require annual staking to hold up tall growth. In spring, insert four stakes in a square or rectangle around the plant. Tightly stretch soft netting over the stakes at a reasonably low level. As the plant grows taller, add another layer of netting as required. As the plant grows, this netting will become hidden.

Avoid wet overwintering conditions.

Attracts bees and other insect pollinators.

New growth may get damaged by slugs and snails.
