SEEDS THAT REQUIRE COLD STRATIFICATION TO GERMINATE

12

ARNICA

Arnica seeds should be soaked for four hours before stratification. They need cool, moist stratification for about eight weeks before they are ready to germinate.

1

ARTICHOKES

Artichoke seeds need just a brief period of cold stratification to germinate. They can go in the fridge for about two weeks. Don’t let these seeds freeze, as they are frost-sensitive.

3

BALLOON FLOWER

These seeds like to be exposed to the sun for germination and can take a while to sprout. They don’t handle transplanting well, so direct sowing is best.

4

BLACK-EYED SUSAN

Cold stratify these seeds for about one to three months and start six to eight weeks before your last expected frost. Transplant once the average temperature reaches 65°F.

5

BUTTERFLY BUSH

Seeds need a brief period of cool, moist temperatures to germinate. Give them about four weeks of cold stratification and then sow indoors eight to 10 weeks before your last expected frost.

6

CATMINT

Put seeds in the freezer for a day, then soak them in water for 12-24 hours before planting. Seeds can be started indoors six weeks before the last expected frost or direct sown once temperatures rise to 50°F.

7

CHAMOMILE

These seeds need a combination of cold and warm stratification to germinate. Keep them warm and moist for two weeks before cold stratifying for about four to six weeks.

8

CHINESE LANTERN

Give seeds two weeks of cold temperatures, and then soak your seeds overnight before planting. You can directly sow these seeds or transplant seedlings after the threat of frost has passed.

9

CONEFLOWER

Plant your seeds in a moist potting mix and cover. Then, place them in the fridge for about four weeks. Keep the soil moist during this period.

10

EVENING PRIMROSE

You can stratify these seeds in their potting mix. Sow your seeds on top of the soil, as these seeds need light to germinate.

11

FALSE SUNFLOWER

These seeds should be kept cold and moist for about one month. The seeds germinate at 65°-70°F, so they should be planted indoors or outdoors when the weather warms up.

12

FUCHSIA

These seeds need about one month of cold stratification before planting. Fuchsia seeds can be unpredictable and take 30 days to germinate on average. Soaking them for 24 hours before planting will speed up the germination time.
