Hosta T Rex

Hosta 'T Rex' is a giant variety, a majestic shade plant that forms a huge clump of very large, deeply veined leaves, of a medium green, slightly trailing. Its summer flowering, in spikes adorned with white bell-shaped flowers, adds to its charm. This sensational plant takes its time to express its full potential, but it deserves a prime location in the garden or in a very large pot on the terrace.

This Hosta, or Funkia T Rex is a horticultural creation dating back to 1999 resulting from the cross-breeding between the Hosta montana macrophylla and the cultivar 'Big John'. It is a completely hardy perennial plant that belongs to the lily or hosta family. From spring onwards this variety forms a giant clump of foliage. The plant, mature in 6 years, will reach a height of 90cm (35in) with a spread of 2m (7ft), if the growing conditions are met. The thick, heavy and slightly soft leaves can measure up to 45cm (18in) long. They are heart-shaped, slightly undulate and have well-marked veins. Their colour is a matte medium green. The flowering takes place in July-August, in the form of elongated white bell-shaped flowers, grouped towards the top of the peduncles that emerge slightly from the foliage. This perennial spreads through stolons, like strawberries. It is a long-lived plant.

The planting of the Hosta 'T Rex' must be carefully considered and wisely chosen, as the plant takes up space and attracts lots of attention. For example, it can be placed in isolation, to emphasise the curve of a shaded alley, on the edge of a woodland, sheltered from the wind, where the soil is deep and fertile. This large hosta will associate well with ferns, meadow rues and Claytonia sibirica, with which it forms beautiful colourful duos that require little maintenance. It will also work well in the company of acteas with purple foliage, columbines and tall foxgloves. All hostas grow well in pots and can remain in the same container for several years. A very large pot should be chosen for 'T Rex', and a special geranium potting soil should be used during the growing season. As long as the foliage is not too dense, watering can be done from the top of the pot. Then place a saucer under the pot where you pour the water, maintaining a constant level in summer.

Most species widespread in Western gardens have been introduced from Japan. Edible, hostas are called 'urui' in Japan where they are commonly consumed.
