Metrosideros excelsa 'Vibrance'

An evergreen upright tree that grows up to 4m tall and 3m wide.

Bright red flowers with vibrant orange-red stamens bloom from mid-December for two weeks. The leaves are leathery grey-green leaves with white hairs on the underside.

Prefers well-draining soils and open positions but will tolerate a wide range of soil conditions and strong winds. Frost tender when young.

Always choose healthy well grown plants and plant after autumn rains as the soil is moist and warm and allows trees and shrubs to become established before winter. This enables them to withstand dry periods during the following summer. Young plants require thorough watering during dry periods over the first two or three years mulching helps to conserve moisture and suppress weeds. Planting success is often improved on clay soils by adding extra topsoil and raising beds. Incorporate coarse sand bark compost or other organic material to improve soil structure. Before planting ensure the root ball is saturated and remove the planter bag or 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 and firm 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 an organic based fertiliser such as blood and bone at a handful per square meter as new growth begins.

Tall plants and those in windy positions require staking to stabilize the root ball until established. Position the stakes in the hole before planting and place the plant between them. Use wide ties that hold securely without chafing tie firmly but allow room for the trunk to increase in girth without constriction. This allows the plant to move a little in the wind encouraging the development of a strong root system without the risk of chafing or root damage

Mulching annually helps suppress weeds and conserve moisture. Organic materials such as sawdust and bark contribute to soil structure as they decompose but keep mulching material away from the trunk. They benefit from a dressing (50g/m2) of general purpose fertiliser in early spring as new growth begins this will encourage more vigorous healthy growth. Sprinkle evenly and work into the top 2 to 3cm of the soil taking care not to damage surface roots.

The first summer and autumn after planting is critical for young plants; water thoroughly during dry periods. Pests and diseases can have serious debilitating effects on young plants; check regularly. Check stakes and ties for chafing and constriction and remove as soon as plants are strong enough to withstand winds without damage.

If any pruning is required to keep plants in shape for their garden situation this should be done after flowering. Metrosideros are sometimes pruned to maintain a desired shape and for deadwood removal.

Relatively free of pests and diseases.

The original tree is planted in a reserve near the sea at Waiomu Bay on the Thames Coast Coromandel Peninsula and was selected by a horticulturist in 1985 when the name "Vibrance" was given to it.
