Anemone are stored and shipped dry and in a vegetative stage. You may think they look like acorns, but don’t worry, they will produce many flowers come Spring.
-
Upon arrival Anemone bulbs can be stored for several months as long as they are stored dry. Indoors a climate controlled building/home works great.
-
Soak or shower the bulbs in water for a minimum of 4 hours up to 12 hours. To maintain levels of oxygen, slow running water is recommended or change water during process. Water temperature should not be warmer than 55F. After soaking, the corms can be planted directly into the ground, or be presprouted.
-
Before planting, it is important to prepare your planting space. Amend the soil with some compost and organic fertilizer. We like to sprinkle in some bone meal to add calcium, which makes the stems stronger come Spring. Plant bulbs in raised beds in a well drained soil. For pot or box cultivation; use a very well drained, sterilized low soluble salt, pH 6 to 6.5 growing medium. We have had success growing anemones in raised beds, and heated or unheated tunnels.

Temperature: 40-50F night, 60F day is ideal. Please provide plenty of ventilation to control temperature and humidity if grown under a structure such as a high tunnel or greenhouse.
How to Grow Anemones
Planting Anemone
Plant in Full Sun to Part Sun. After the soak and recommended pre-rooting period, bulbs can be planted directly in the ground or in cells and transplanted later. Plant Anemone with it’s point down facing.
Spacing for Anemone bulbs is about 6-8” apart. Plant anemones 1-2” deep, under the soil surface.
Apply a layer of mulch, straw, or leaves around the plants to help protect them from winter elements.
Watering Anemone
If possible keep foliage dry, and use drip irrigation if available. Do not make the soil too wet, therefore drainage and raised beds is very important. Water well once after planting and wait for spring to water, unless the soil is bone dry. Regular rainfall will provide enough water until the temperatures warm in the Spring.
Keep soil cool and moist, but not wet! Soil temperature needs to remain below 55F (12.5C) all along the growing cycle. Long periods of warmer soil temperature will trigger the plant to die back into dormancy, just like warm spring would do. Water as needed during active growth periods
Harvesting Anemone
Anemones typically start to flower about three months after planting. Fall-planted anemones will bloom Early Spring for 8-10 weeks. Early Spring planted anemones will bloom by Mid-Spring and continue blooming for 6 weeks. Our plants generally produce continuously until heat renders them dormant.
Anemone will open during the day and close at night. Ideal cutting stage is when flower is closed (early morning) after the 2nd day of opening.. Cut the stem all the way down at the soil level, be careful not to cut new stems forming at the soil surface. Store flowers cool in water.
Remove the foliage when blooming ends and the leaves turn yellow so the bulbs can rest for a few months until the next growing season.
For Anemones, you want to harvest when the distance between the collarette and the flower is about 3/4" to 1". You will notice the first stems of Anemones will be
really short. If you bought a series suitable for cut flower production (Jerusalem, Galilee, Carmel, Marianne, Meron, Mistral, etc), notice that stems will lengthen as the weeks go on. Some of our stems get up to 20" long.

Once daytime temperatures reach the mid to high 80s for consecutive days, the plants will enter dormancy, concluding your harvest. You will notice plants go dormant when the leaves start to turn yellow.
When this occurs, you can choose to leave the corms in the ground to possibly perennialize, or simply pull the corms out and toss in the compost, making way to plant something new.
