Cultivation
Herbs to propagate by seed
Seeds are not viable in cold climates.
Optimal temperature is around 70F (21C).
Seeds germinate at temperatures around 60-65F (15-18C).
Not recommended because of erratic germination.
plant seeds on site or in small pots.
sow seeds in situ, in spring or early autumn.
Plants grown from seeds often have unpredictable appearances.
Germination is slow and unreliable.
Sow fresh seeds, which need stratification to germinate.
Optimal temperature between 56-70F (13-21C).
Possible though unreliable method to propagate Geranium.
Chenopodium bonus-henricus
sow seeds in succession to ensure a constant supply.
Germination can take a long time and be quite erratic.
Take the seeds from ripe berries. Seeds are extremely slow to germinate and grow.
Sow fresh seeds on soil surface.
Difficult to germinate, especially in cool climates.
Sow seeds preferably in autumn, for wintering.
Plants grown from seeds may be of inferior quality.
Soak seeds in warm water overnight for faster germination.
Some poppy species require winter stratification to germinate.
Sow fresh seeds. May need winter stratification if dry seeds are sown in autumn.
Tanacetum cinerariifolium
Certain species can be grown from seed.
Not recommended as germination is erratic.
Santolina chamaecyparissus
Germination can be a long and difficult process.
sow on soil surface, as seeds need light to germinate.
Seeds require a winter season before germination.
Sow fresh ripe seeds. Require stratification to germinate.
Not all thyme species can be grown from seed.
Do not cover seeds with soil.
Sow at temperature around 60-65F (15-18C).
sow on soil surface, as seeds need light to germinate.
