China aster Violet Mix

China asters are grown relatively densely. The ideal spacing for planting is 12 × 12 cm to 15 × 30 cm. This closer spacing helps the plants gently lean on each other for support. Remember to transplant the seedlings directly from the seed tray into the flower bed; unnecessary intermediate steps (such as repotting into larger pots) do not benefit them.

At the end of the season, mature plants can only withstand frosts down to 0 °C.

While young seedlings are slightly more resilient and can survive short-term temperature drops (down to -6 °C), it is best not to take unnecessary risks. The safest approach is to wait and plant the seedlings out into the garden bed only after the last frosts in mid-May (after the 'Ice Saints').

Yes, support is definitely recommended for these China asters. The plants reach an impressive height of 50 to 100 cm.

If you are growing China asters for cut flowers, setting up a support net (for the stems to grow through) is almost a necessity. Without support, the stems would easily warp or bend due to rain and wind, and you would lose your straight flowers for vases.

Unfortunately, this rule does not apply to China asters. As previously mentioned, China asters react to the shortening length of the day (after the summer solstice).

This means that whether you plant the seedlings gradually or all at once, all the plants in the bed will sense the shorter days at the same time and begin to bloom at roughly the same time—that is, at the turn of July and August. Therefore, a single, high-quality sowing is perfectly sufficient.

No, under no circumstances should you pinch China asters. They have a natural ability to branch out profusely on their own. Pinching them would only unnecessarily weaken them, disrupt their growth, and significantly delay the time of their first bloom.

China asters are plants that require stable warmth to germinate. Maintain a temperature between 20 and 22 °C. With the correct temperature and humidity, you will usually see the first sprouts in 5 to 10 days.

Sowing China asters requires a specific method for the seeds to germinate well:

• Place 1 seed in each cell of the seed tray.
• Do not cover the seeds with substrate. China asters need light to germinate. Instead, cover them with a thin layer of vermiculite, which lets light through while maintaining the necessary moisture.
• Water only from below (by letting water soak up from a tray underneath) or by very gentle misting. A strong stream of water would wash the seeds away.

To achieve an even representation of all purple shades, we recommend always sowing the entire packet of seeds.

We do not recommend direct sowing into the flower bed, as you will not achieve good results in our climate conditions.

It is ideal to start the China asters indoors or in a greenhouse. Sowing in seed trays should take place between March and May. The seedlings will spend approximately 4 to 6 weeks in the tray before they grow to the right size and are ready for transplanting outdoors.

China asters love sunny spots, but will also grow very well in light shade.

As for the soil, they require loamy, humus-rich, and sufficiently well-draining soil. Before planting, it is a great idea to incorporate high-quality, well-matured compost into the bed. The plants need moderate watering, so keep the soil moist but avoid overwatering.

In addition to Fusarium wilt, China asters occasionally suffer from fungal diseases such as powdery mildew or gray mold (Botrytis cinerea), which thrive especially in humid and poorly ventilated environments.

As for pests, they are most often threatened by aphids, spider mites, and thrips. We recommend checking the plants regularly and implementing natural or chemical protection in time if problems arise.

China Aster Violet Mix (Latin: Callistephus chinensis) is a beautiful annual produced by Loukykvět that offers a colorful mix of all shades of purple—from pastel pink, through lavender and lilac, to deep violet.

Asters respond to day length. The flowers begin to form and appear with the arrival of shorter days, so you can expect the most abundant blooming from late July, through August, and into September. The flowers reach a size of up to 8 cm.

You can be completely worry-free; China asters are not poisonous at all. On the contrary, they are fully edible!

Their beautifully colored purple petals can be safely plucked and used as an edible decoration to liven up summer salads, desserts, or drinks. While they do not have a strong flavor, they are visually irresistible.

Yes, China asters are a very useful plant for your garden. Their flowers are proven to attract pollinators such as bees, bumblebees, and butterflies. Especially in late summer and autumn, when few other plants are blooming, China asters represent a valuable source of food.

However, the flowers themselves do not have any distinctive aroma, so they do not smell to us.

The best time to cut China aster flowers is early in the morning or in the evening, when the plant is fully hydrated. The flowers should be almost or fully open, as China asters do not continue to bloom much once cut, unlike some other flowers.

For maximum vase life, remove all leaves from the lower part of the stem so they do not sit in the water and rot. Change the water in the vase every day.

China aster Violet Mix is an absolutely phenomenal choice for cut flowers. Its sturdy, straight stems (when grown with support) and beautifully shaped flowers with a diameter of 8 cm stay fresh in a vase for a very long time.

Conversely, these China asters are not suitable for drying. During the drying process, the flowers lose both their shape and their vibrant purple color.

This problem is caused by Fusarium wilt (Fusarium rot). It is a troublesome fungal disease that persists and spreads in the soil and causes the entire plant to collapse in China asters.

Because of this rot, there is a strict rule not to grow China asters in the same spot as last year. Always find a new location for them in your garden and wait at least 2 to 3 years before returning to the original spot.
