Item Description:
PROPAGATION MATERIAL PROVIDED ON REQUEST
The first two photos are of a young seedling plant in a 50 mm tube, and the last two of an older one in a 90 mm bottomless pot. Both can be purchased outright here if in stock.
If not in stock please do enquire, as I am most happy to repot any self-seeded ones about, which are small enough and strong enough to send. Or I may have seed I can send.

The listed price is an indication only, assuming a young seedling in a 50 mm tube. The actual price may vary depending on your requirements.

I am most happy to discuss your needs with you, and supply accordingly.

The seedling in the first two photos is about 90 mm tall, and about 120 mm tall in the last two.

Plant Description:
Herb Robert is a true geranium which grows to about 300-400 mm high. It is a famed medicinal herb with internal and external healing properties.

The plant has a delicate appearance and produces dainty 15 mm diameter mauve flowers in spring through to autumn.

Growing Information:
Herb Robert is moderately frost-tolerant, prefers moist soil, and can grow in semi-shade to full sun in temperate climates. (It will do better in part-shade in very hot climates.) Leaves and stems may turn red in full, bright, sun.

This plant is propagated by seed, and self-seeds readily. However, the timing of seed collection is crucial, as the seed capsules have an ‘explosive’ nature and will propel the seed some distance away and in all directions. To collect by hand, either pick the seed pods when they are about 2 cm long and feel plump and hard between two fingers, or simply cover the pods with a breathable bag to trap the expelled seeds when the capsule opens. If picking the capsules, allow to dry for 3-4 days minimum. Sow seed in a shady spot to 5 mm depth for best germination, which can take up to six weeks. Keep moist with regular watering.

Alternatively, take advantage of the ‘explosivity’ by keeping a flowering plant in a pot and placing this where you would like more to grow. Repeat by moving the plant to another location as other capsules mature and show signs of opening.
