Saponaria officinalis SOAPWORT (15 seeds)

Soapwort, also known as Bouncing Bet, Soapweed, or Saponaria officinalis, is an herbaceous perennial belonging to the Caryophyllaceae family. This fast-growing plant, native to European meadows, typically reaches a height of 30 to 80 cm.

Its leaves are simple, lanceolate, thick, slightly hairy, and dark green. They measure approximately 5 to 10 cm in length. The star-shaped flowers, 2 to 4 cm in diameter, are clustered together and feature five petals ranging from pale pink to white. The lightly fragrant bloom occurs from May to September.

Soapwort seeds are small, smooth, black, and measure about 2 millimeters in length.

- Uses:

The flowering tops of the soapwort can replace soap for washing delicate clothes that are prone to fading. It earned its name "Soapweed" because it contains a high concentration of saponin, a substance that produces a lather similar to dish soap.

Historically, its dried and powdered roots were used for washing hands, and when mixed with soda, they were also used to bleach wool.

- Germination and Sowing:

• The ideal period to sow soapweed generally begins in early May.
• Sow the seeds in a tray of fine potting soil.
• Cover them with only 1 to 2 millimeters of soil.
• Press down lightly by hand to ensure contact.
• Water manually using a spray bottle.
• Place the tray in a greenhouse in a warm, humid environment at a temperature of around 20°C. Germination will typically begin 2 to 3 weeks after sowing.

- Soil Type:

Soapweed appreciates cool, well-drained, fertile soil enriched with compost. It thrives in soil composed of clay, sand, or even river silt.

- Exposure:

Bouncing Bet loves full sun, although it can tolerate light shade. Sunny exposure will promote more abundant flowering.

- Watering:

This plant particularly enjoys water. It is recommended to water it twice a week during the peak of summer. It is important to keep the soil slightly moist but never waterlogged.

- Temperature / Hardiness:

Common soapwort is very hardy and can withstand cold temperatures down to -15°C. It grows rapidly when temperatures vary between 20 and 27°C. Its USDA hardiness zone is 3–9.

- Multiplication:

There are two effective ways to propagate soapwort: either by taking cuttings or by sowing seeds in the spring.
