Tanacetum parthenium
Feverfew
The feverfew, Tanacetum parthenium, has small white flowers with yellow centre above a cut foliage. It gives a rural look to the edges and bouquets. This species is distinguished from the German chamomile commonly used in infusion; this sheet gives priority to its ornamental interest in the garden. These organic seeds from Jardins de l’écoumène let you start your own plants and follow their development from sowing onward. Plan the arrangement around each plant’s mature habit and the distance from which the flowers will be viewed. Position smaller flowers close to a path for easy viewing, while taller plants can provide a focal point at the back of a bed.

Tanacetum parthenium — Feverfew. The feverfew, Tanacetum parthenium, has small white flowers with yellow centre above a cut foliage. It gives a rural look to the edges and bouquets. This species is distinguished from the German chamomile commonly used in infusion; this sheet gives priority to its ornamental interest in the garden. These organic perennial flower seeds from Jardins de l’écoumène let you start your own plants and follow their development from sowing onward. Plan the arrangement around each plant’s mature habit and the distance from which the flowers will be viewed.
Recommended planting period: March to June. The depth to be respected is 0.3 cm (0.1 in.). Germination usually takes 10 to 21 days. For germination, keep the soil at 18 to 22°C (64 to 72°F). Transplant the young flowering plants once their true leaves have developed and their roots hold the root ball together. Handle the seedlings gently and avoid squeezing their delicate stems. Under grow lights, gradually space the containers farther apart so that the foliage does not overlap. Hardening off then prepares the plants for outdoor sunlight, wind and changes in temperature.
The feverfew bears small white flowers with yellow hearts above a cut foliage. Its stems slip into the bouquets and its bearing forms a transition between the lower plants and the higher flowers. Plan the arrangement around each plant’s mature habit and the distance from which the flowers will be viewed. Position smaller flowers close to a path for easy viewing, while taller plants can provide a focal point at the back of a bed. Repeat groups of the same variety to create a clear, visible colour pattern. Leave room to reach the plants for cutting, and avoid crowding clumps simply to fill the space right away.

Growing method
Recommended planting period: March to June. The depth to be respected is 0.3 cm (0.1 in.). Germination usually takes 10 to 21 days. For germination, keep the soil at 18 to 22°C (64 to 72°F). Transplant the young flowering plants once their true leaves have developed and their roots hold the root ball together. Handle the seedlings gently and avoid squeezing their delicate stems. Under grow lights, gradually space the containers farther apart so that the foliage does not overlap. Hardening off then prepares the plants for outdoor sunlight, wind and changes in temperature. Plant outdoors once the conditions are suitable for the plants’ cold tolerance. Watch the progression from flower buds to open blooms and faded flowers to decide which care the plant needs. A cut must preserve the shoots that will bloom afterwards. Check the supports on tall-stemmed plants after a period of strong wind. Lightly removing damaged growth helps maintain the plant’s shape without leaving it bare. Adapt the end of the season to the cycle of the plant: annuals and perennials do not require the same preparation for winter. Choose between prolonging flowering and keeping seeds on a few stems.
Soil and care
Soil & care
Watering
Keep the seedbed surface slightly moist until seedlings emerge, using a gentle spray that does not displace the seeds. After rooting, water at the base of the plant when the soil begins to dry and allow excess water to drain. Avoid small, too frequent applications that wet only the surface. In a container, check the needs more often during hot or windy days. Adjust the frequency to precipitation, drainage and plant development.
Soil type
Prepare well-drained soil for planting. Transplant the young flowering plants once their true leaves have developed and their roots hold the root ball together. Handle the seedlings gently and avoid squeezing their delicate stems. Under grow lights, gradually space the containers farther apart so that the foliage does not overlap. Hardening off then prepares the plants for outdoor sunlight, wind and changes in temperature.
Fertilization
Fertilization supports growth and should take into account the nutrients already present in the soil or potting mix. Use mature compost or a fertilizer suitable for the crop, following the recommended application rate. Avoid combining too many products, especially in a container where the roots have a limited volume of growing medium. Water as needed after applying nutrients, and observe foliage growth before deciding whether another fertilizer application is necessary.
Moisture
Keep the growing mix moist during germination, without standing water; then adjust to the crop

Container growing
Container growing
Recommended pot size
A stable container with drainage holes, enough width for the plant’s spread and sufficient depth for its roots
Choose a location in full sun. Reserve this spread around the plant: 30 to 45 cm (12 to 18 in). A flowering container arrangement should leave enough room for every plant to grow. Place upright plants where they remain visible, and let any trailing stems extend over the container’s edge. Check that the combined plants share the desired exposure and moisture. After a few weeks, check where the plants are becoming crowded and remove only damaged parts or stems that disrupt the balance of the arrangement.

Bloom period
Flowering usually occurs in this period: June to September. Decide which stems to keep flowering and which to leave in place so that they can develop seeds. Deadheading is suitable for many annuals, while developing seed heads and dried flower clusters can also provide ornamental interest. Keep plants labelled after flowering ends, and remove self-sown seedlings that are growing in a path.

Garden associations
Companion plants & uses
Companion plants
In a mixed planting, you can reserve sections close to these plants: mint, lavender, yarrow. The association is used here to organize space and crops. Allow for the height, light requirements and water needs of each plant, leaving enough room between the foliage. Keep a path clear for watering and harvesting, then remove finished crops to make room for the next planting. This arrangement makes maintenance easier without promising protection against garden pests. Plan the arrangement around each plant’s mature habit and the distance from which the flowers will be viewed.

Wildlife & precautions
Supporting wildlife
The flowers can provide a place for visiting pollinating insects during the growing season. Grow several plants in a sunny area that visiting insects can reach, and avoid applying treatments to flowers while they are open. Leave some flowers in the garden for visiting insects if you are also cutting stems to use in bouquets.
