Key information
Description
Deciduous perennial ornamental herbaceous plant, up to 60 cm tall. Appreciated for its blossom that rises from the dense foliage, lending elegance and colour to gardens, in flowerbeds or borders, and to terraces in pots or tubs, also in compositions with other species.
Variety description
Perennial plant with a spring-summer flowering. Ideal for use in rock gardens and hanging gardens. Flowering is very long-lasting.
Origin and history
Curiosities and special features
Approximately 65 species belong to the botanical genus Tradescantia, including some used as indoor plants such as Tradescantia fluminensis and Tradescantia zebrina, while others are suitable for adorning gardens and terraces such as the hybrid T. x andersoniana (Andersoniana Group).
Origin and distribution
Hybrid obtained by crosses between species belonging to the same botanical genus, native to Central and South America.
Main features
Flower size
The flower individually is small, grouped together with others in an elegant inflorescence.
Leaf
Leafs have elongated lamina.
Flowering period
It flowers from mid-spring to early autumn for a duration of 60 to 90 days.
Inflorescence
Inflorescence umbrella.
Leaf colour
Solid-coloured leaf, in perfect colour balance with the shades of the inflorescences.
Plant height
The height of the plant varies from 0.3 to 0.6 m.
Lifespan
Herbaceous perennial. It loses its aerial part in winter and then vegetates again the following spring.
Where to plant
Versatile, it is suitable for decorating flower beds, planters, rock gardens, outdoor tubs
Stem
The stem is herbaceous and the variety has no thorns.
Flower
The flower is simple in form, small in size, with a gamopetalous corolla and single-coloured petals. It is arranged in small umbel inflorescences. It flowers from mid-spring to early autumn, with a flowering period of between 60 and 90 days. It is attractive to bees and butterflies.
Growth
Variety with medium to vigorous growth.
Plant habit
The habitus is erect.
Branching
It develops with medium branching.
Growing conditions
PH
It requires a slightly acidic soil or growing medium pH of between 6.0 and 6.5.
Soil preparation
Before transplanting in mid-spring, carry out light digging, removing weeds, any previous crop residues and bulky stones. In addition, add professional-quality substrate to the surface by approximately 5/10 cm, levelling out carefully with a rake.
Sun exposure
Exposures in half shade, full sun are suggested for best growth and flowering results.
Ideal climate and temperature
The ideal temperature is between 15 and 22 °C. The vital temperature is between -10 and 35 °C
Use
Variety suitable as a plant in:
Outdoor ornamental
Hardiness
Variety of medium hardiness, fears prolonged waterlogging.
Soil
For proper vegetative growth and luxuriant flowering, the ideal soil for Tradescantia x andersoniana is medium-textured, structured and well draining. Soils that are too heavy reduce the development of the vegetation. For pots and tubs, choose a new, high-quality substrate for spring plants.
Difficulty
Easy to cultivate, it requires a low level of management effort following proper establishment in the new planting site.
Growing tips
To prevent root rot and yellowing of the vegetation, it is advisable to
Avoid over-watering
Combinations with other plants
Ideal for compact and colourful ornamental compositions, also in combination with flowerings with different heights in order to create perspective views; the colour combinations may involve shades of the same hue or an alternation by composing patterns or patterns according to personal fantasy. Colour spots or simple borders can be formed with other species such as Bergenia, Hosta and Lysimachia. Even in a smaller space such as pots or tubs, it can be placed alternately with plants with green or variegated foliage or by combining, as in a garden, species with flowers in different shades.
Care and plant health
Planting
For bed planting, apply an average density of 12 plants per square metre in order to ensure correct development of the root and aerial apparatus of each specimen, thus obtaining a harmonious and proportionate final composition. Adopt a suitable planting pattern also for mixed compositions with other species, in consideration of the final development achieved by each individual plant.
Propagation
Propagation can be by seed and by division of the head.
Watering
Use rainwater, or alternatively aqueduct water with an optimal sub-acidic pH, either manually or by means of an irrigation system, keeping the soil or substrate moist at all times but free from waterlogging that can lead to leaf yellowing and root rot.
Fertilising
During the spring-summer period, apply a specific fertiliser for ornamental species to the soil or substrate at the foot of the plant, to be distributed in liquid form, i.e. diluted in the irrigation water, without exceeding the frequency and doses applied.
Edibility and toxicity
Edibility for humans
Non-edible.
Toxicity for humans
Wear gloves when handling.
Expert advice
Tip
It is an interesting plant for mixed flower beds with perennials and spring blooms. It disappears in winter and vegetates again in spring. Avoid planting in soils too rich in clay.
