Saponaria lempergii

Soapwort (Saponaria lempergii) is an erect perennial plant with attractive bright green leaves and small flower heads made up of five petals. It is native to Western and Central Europe but can be grown all over the world. Soapwort can reach up to a meter tall and has an extensive root system and long, trailing stems with white, pink, purple, and yellow flowers which all bloom throughout the spring and summer months. The leaves and flowers of this plant are rich in saponin, and can be used to make a soapy, foaming solution when mixed with water. This solution is traditionally used for cleaning laundry, dishes, and even hair! In addition, Soapwort has also been used to make traditional medicines and tonics.

watering

Soapwort plants (Saponaria lempergii) need consistently moist soil and regular watering to thrive. Water in the spring when the soil is warming up to revitalize the roots and bring new growth. In summer, water your soapwort plants 1-2 times per week, allowing the top 1-2 inches of soil to dry out in between. If the plants start to look limp, give them a deep soak. During the fall as the temperatures cool, you can reduce the amount of water you give your soapwort plants to once a week. In winter, if the soil hasn't frozen, water your soapwort plants once a month until they resume growth in the spring.

sunlight

Soapwort (Saponaria lempergii) does best with around 12 hours of direct sunlight during the summer months and at least 6 hours of indirect sunlight for the other months. During the spring and fall, it is best to give the plant bright indirect light. In areas with cooler climates, the soapwort should be kept in bright indirect light during the winter months. Soapwort is able to tolerate a range of light conditions, but it will not do its best without plenty of sunshine.

pruning

Soapwort should be pruned each spring. This species should be lightly pruned, removing only a few of the oldest branches each year. This helps to maintain the shape of the shrub and encourages new growth. When pruning, take care to avoid evergreen varieties, as these will not regrow after pruning. When pruning, take care to avoid branches that are full of flowers as this will affect the blooming of the plant. Pruning should be carried out before new growth begins, generally in the middle to end of spring.
