Description
This is the "florist's geranium," the one that many professionals continue, against all odds, to call "Geranium," thus causing confusion in the minds of beginner enthusiasts with the true geraniums, which are perennial plants perfectly adapted to our climate.
Medium-sized clump of reddish ramified stems, bearing small leaves measuring 3 to 5 cm (1 to 2in) in diameter with shallow and rounded lobes, of a very dark green colour marked with a dark brown circle. The medium-sized vermillion flowers are carried in small umbels. A very unique variety due to the colour of its foliage, which appears almost black in full sunlight, and its long-lasting flowering.
Note: Please be aware that our young plug plants are professional products intended for experienced gardeners: upon receipt, transplant and store them in shelters (veranda, greenhouse, cold frame) at a temperature above 14°C (57.2°F) for a few weeks before being installed outdoors once the risk of frost has definitively passed.

The South African origins of almost all pelargoniums does not allow them to be grown without risk throughout the year in our gardens, except in the mildest regions, and even then, very close to the Mediterranean where frost never happens. We have observed on several occasions that they can withstand temperatures of around -4°C (24.8°F) for 2 to 3 days, provided that the soil is dry. Most of the time, growing them in pots is necessary and these should be brought inside during winter, preferably in a bright, well-ventilated, frost-free room, but without heating. When the temperature remains low, between -1°C (30.2°F) and +7°C (44.6°F), watering should be practically stopped for several weeks and only resumed when the days lengthen and the temperature significantly rises. There are various methods suggested here and there to preserve them during winter: garage, cellar, laundry room, attic, hanging upside down... The results are rarely successful. Believe me, the best solution remains the one we give you: a very bright room, preferably unheated. If you don't have a room resembling this more or less, don't expect to keep your pelargoniums for very long. These plants are hungry and therefore require a suitable substrate. A mixture of 1/3 garden soil, 1/3 compost, and 1/3 well-rotted manure is suitable for them. Repotting should be done every year in spring with fresh soil, as well as a heavy pruning to remove all the thin branches that have become "leggy" during winter due to lack of light. The plants are either natural-looking botanical species or varieties that we have chosen for their originality.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).

The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:
- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
