Corylus maxima 'Purpurea'

Also Known As - hazel
Purple Filbert (Corylus maxima 'Purpurea') is a deciduous shrub with an upright growing habit and multiple stems. It's an ornamental shrub with purple-bronze foliage throughout the year. Featuring frilly, lacy, scalloped leaves, with a purplish-maroon shade, its leaves turn several shades brighter in the spring and the deeper colour in the fall season. Producing spacious clusters of purplish-pink male catkins, this species can reach a height of 10-12 feet and spread 6-10 feet. Being an ideal choice for screening and solitary tree, it tolerates partial shade and a wide range of soils.

watering

For best results, water Purple Filberts once a week, allowing the soil to dry out slightly between waterings. Water deeply, saturating the soil to a depth of 8 - 12 inches, letting the water drain after each watering. In hot and dry weather, water more frequently to prevent wilting. Avoid leaving the plants water-saturated for long periods of time, as this can lead to root rot.

sunlight

Purple filberts (Corylus maxima 'Purpurea') thrive in full sunlight or partial shade. When grown in full sun, Purple Filberts should receive around 6 to 8 hours of direct sunlight each day. When grown in partial shade, Purple Filberts should receive at least 4 hours of direct sunlight each day, with the remaining hours in dappled sunlight. Avoid planting Purple Filberts in dark or heavily shaded areas, as these will reduce its time in direct sunlight, which can result in unhealthy or stunted growth.

pruning

Purple filbert can be pruned at any time of the year but should be pruned lightly in the spring and then pruned more heavily in the summer. In the spring, prune away any weak or dead growth and reduce the size of any limbs that have grown too long. In the summer, pruned away any weak or dead growth as before but also remove some of the bottom branches to allow for better air flow and light penetration. Pruning should be kept to a minimum, no more than a quarter of the plant each year.
