The Sweetwilliam is medium in size and 45 cm in height; in the spring, summer, autumn, winter it assumes a red colouring.

Plant which needs at least a few hours a day of sunlight. We suggest growing the The Sweetwilliam outdoors year round, as they don't fear cold weather.These plants lose the aerial part during the coldest months of the year. As spring begins, stems and leaves quickly start to reproduce.
Watering takes place only when the soil has been dry for days, usually every 1-2 weeks can be enough; if the climate is particularly hot we can slightly intensify the irrigations, using 2-3 glasses of water . Perennial plants are subject to some months of vegetational rest. During these months it isn't necessary to water them.
Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate.
We suggest a substratum characterized by an excellent drainage.
