About Eastern Cyclamen

Cyclamen coum · also called Eastern cyclamen, Eastern sowbread · flowering

Cyclamen coum is a dwarf, tuberous perennial native to the eastern Mediterranean region from Bulgaria to Turkey, Lebanon, and the Caucasus, producing jewel-like magenta, pink, or white flowers with reflexed petals from December to March, making it one of the most valuable winter-flowering garden plants. The rounded, dark green to silver-patterned leaves are attractive from autumn through spring. It thrives in the dry shade under deciduous trees and shrubs, naturalising in leafy soil where it can be left undisturbed. All parts are highly toxic to cats and dogs due to saponins.

Plant type: flowering

The reasons eastern cyclamen isn't blooming

Almost every non-blooming eastern cyclamen traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding eastern cyclamen a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get eastern cyclamen to flower

Maximise sun. Give eastern cyclamen the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for eastern cyclamen and get the feeding right with the eastern cyclamen fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Eastern Cyclamen flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full eastern cyclamen care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Eastern Cyclamen blooming — frequently asked questions

Why won't my eastern cyclamen flower?

Eastern Cyclamen blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make eastern cyclamen bloom?

Give eastern cyclamen the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
