The inflorescences of autumn helenium are baskets, collected in apical corymbose inflorescences.
Helenium autumnal has reed flowers that are yellow, red, and tubular flowers that are dark yellow.
Flowering occurs in July and lasts 60 days.
How to plant helenium
It is necessary to plant heleniums in open ground at the end of spring, otherwise frosts on the soil cover will harm the plants.
The flowers are light-loving, but at the same time shade-tolerant.
They don’t like stagnant moisture, so good drainage is a must when planting.
When preparing soil for seedlings, turf, leaf and garden soil (2 parts) are usually mixed with coarse sand (1 part) and well-rotted compost or humus (1 part).
Gardeners also add high-moor peat, which has neutral acidity, to the soil.
What does helenium like
Heleniums love good, fertilized soil, moist and neutral in acidity. Sunlight is very important for them; areas in the shade are not for helenium.
In nature, they grow in meadows, where there are many different grasses and the soil retains moisture for a long time.
How to prepare helenium for winter
If the winter is snowy or without severe frosts, young plants overwinter well, and in frosty and snowless winters they easily freeze out.
When preparing for winter, mulch the plant with moss or sawdust and cover it with lutrasil.
For better wintering, trim and mulch adult plants as well.
