Pinus parviflora 'Glauca'

Glauca

Trees can play a special role in the garden. As a focal point or specimen tree or as part of a woodland garden, they bring the benefits of structure and form and can be characterful too. Some of the most interesting trees, offering a variety of shapes and sizes can be found in the widespread and versatile pine family. The pine in all its 120 species is found from the Arctic Circle to Central America, Europe, North Africa and South East Asia. Although the basic forms of needle-like leaves, cones and bark show similarities throughout the species, there is wide variation in terms of colour, growth habit and size. Whilst many gardeners would like to have a tree in the garden, space in relation to the size and spread of the tree as it matures is an important consideration. The pine family has an answer to this no matter what space is available. From the Giant Redwood to the diminutive dwarf conifers - there is a pine for every situation.

It is important when selecting a pine that you choose the right one for your garden, and for many of us that means one that won't grow too big or too fast. Pinus parviflora 'Glauca' is a medium-sized variant of Pinus parviflora, also known as the Japanese White Pine. Its twisted branches and bluish or 'glaucus' foliage provide interesting shapes and colour all year round. Scaly, purplish brown bark adds an additional texture to the garden. This pine is slow growing and height and spread can vary depending on soil type and prevailing conditions. However, over the course of time, it should reach a height of around 10 - 12m and a spread of approximately 5 - 7m.

Pinus parviflora 'Glauca' has the presence to stand alone as a specimen tree and is likely to generate interest from visitors because its shape differs from the symmetry normally associated with pines. The twisted branches could be interpreted as giving a sense of antiquity to the tree, even in its early years. This may be advantageous from a garden design perspective when the aim is to create an established feel early on in the life of a new garden.

Pines do best in well-drained soils, in a full sun position. However, they are tolerant of a wide range of conditions. Pinus parviflora 'Glauca' is an attractive, interesting tree that will give enjoyment for years, whilst asking nothing of you in return.
