Teucrium flavum grandiflorum
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Teucrium hyrcanicum atropurpureum
E
Sow @ 20°C for 6 weeks, then place @ 4°C for 6 weeks, then slowly raise temperature to 10°C for 6 weeks. If there is no germination, repeat the cycle. This mimics fall sowing outdoors for spring germination.
Teucrium scorodonia
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Thalictrum lucidum
*
This species needs special care as described.
20°x 4 weeks, 4°C x 6 weeks, then 20°C
Thalictrum actaeifolium
K
Sow @ 10°C. Most species for which we suggest this temperature will also germinate at 20°C, but prefer the cooler temperature for sturdy growth.
Thalictrum baicalense
L
Expose to fluctuating outdoor winter temperatures including freezing for 3 months. Gradually increase light and temperature in spring.
Thalictrum chelidonii
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Thalictrum dasycarpum
H
Use repeated cycles of 4°C, then 20°C for 3 months each. Germination is very prolonged.
Thalictrum dipterocarpum
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Thalictrum flavum
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Thalictrum flavum 'Illuminator'
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Thalictrum flavum glaucum
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Thalictrum flavum ssp. glaucum
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Thalictrum foetidum
K
Sow @ 10°C. Most species for which we suggest this temperature will also germinate at 20°C, but prefer the cooler temperature for sturdy growth.
Thalictrum minus
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Thalictrum minus 'Adiantifolium'
B
Sow @ 20°C. If seed does not germinate within 3 months, try 4°C for 1-2 months, then 20°C again.
Thalictrum polygamum
!
Sow immediately. The viability of these seeds is short or the species propagates best with fresh seed. Stored seed might be coaxed into germination with temperature cycling and patience.

Thalictrum simplex minus
Thalictrum simplex ssp. galioides
Thalictrum sp.
seed viability < 1 year
