I’m familiar with these flowers’ characteristics. They can be propagated from both cuttings and seed. In their first year, a plant can produce up to 80 buds, and in the following year, over 800. The flowers can last in water for 30 to 35 days.
Korean chrysanthemums can withstand frosts down to 10°F and will resume blooming once temperatures rise. Their roots remain unharmed even at −20°F to −25°F in winter. They don’t need special covering and do well under snow. You can also time their blooming to coincide with birthdays, name days, or anniversaries.
From observing their development, I concluded that it takes about 3 to 3.5 months from sowing seed to flowering, 35 to 40 days from cuttings to flowering, and 40 to 50 days after dividing rhizomes to flowering. To have Korean chrysanthemums bloom by May 1st, sow them in February and take cuttings at the end of March. Keep in mind that these timelines depend on air temperature and the variety (early, mid-season, or late).
Korean chrysanthemums are still relatively rare in our country.
