Although there are several cultivars for Anemone Coronaria you are most likely are going to find only two in your area De Caen and St. Brigid. The De Caen types look like poppies and the St. Brigid ones have double flowers. If you want some taller flowers for that wow factor then you should check out my recent article Oriental Lily ( Oriental Hybrid Lilies ).
Anemone Coronaria Characteristics
Anemone Coronaria is part of the Anemone or Windflower family, these are perennial bulbs although you can grow them from seed as well. If you are planting bulbs you should soak them in water for a couple of hours, this way they can absorb as much water as they need and they will have a better chance of survival than without soaking.

Anemone Coronaria Hardiness Zone
The Anemone Coronaria is hardy between zones 7-10, in these zones they are considered perennials which means that they will come back every year. In zones outside 7-10 you can still grow them but as an annual plant, which means that you have to dig them up in the autumn and replant them in the spring.
Anemone Coronaria Sun Requirements
Anemone Coronaria requires full sun, although in hotter environments you can definitely grow them in partial shade. The one thing that they do not tolerate is full shade, oftentimes the plants will get stunted and rarely produce any flowers. Even in hotter environments, you should ideally let them get at least a couple of hours of morning sun. If you are searching for a beautiful small flowering plant then check out my recent article Winter Aconite ( Eranthis Hyemalis Zones 4-7 ).
Anemone Coronaria Water Requirements
The Anemone Coronaria has moderate water requirements, but it tends to be sensitive to overwatering. Once it starts flowering it is a good idea to give them some extra water, but other than that just water them as you do all your plants.
Anemone Coronaria Drought Tolerance
The Anemone Coronaria has some drought tolerance, but it really depends on the geographic location. In the northern parts of the county, it will tolerate drought for some time, but in hotter climates, it will get stressed out if it doesn’t get enough water especially when flowering.
Anemone Coronaria Height And Spread
The height of the Anemone Coronaria is around 10 – 24 inches ( 25cm – 60 cm ), its spread is around 7 – 9 inches ( 18cm – 23cm ). These flowers look the best when you plant the bulbs in bigger clumps, and the ideal place for them is in the middle of the flower border.
Anemone Coronaria Flowering Period
The Anemone Coronaria flowers twice per year, it not only provides spring interest but also beautiful flowers in the fall as well. It tends to bloom between April and June for the first time, and the second time in August or October.
Anemone Coronaria Planting
Before planting the Anemone Coronaria bulbs you have to soak them in lukewarm water for 4-6 hours, and you will notice that the bulbs will swell up. Just a word of caution, it is better to soak it less than to soak them for too long like leaving it overnight in water. Once they are soaked dig a small hole a couple of inches deep and plant the bulb. As the bulbs are rather small it doesn’t really matter which side will be up.
After this fill in the hole with garden compost or garden soil, and if you have soaked the bulbs then you can skip watering it. You can plant the bulbs without soaking them, just make sure to water them well after you have planted them.
Anemone Coronaria Staking
The Anemone Coronaria does not need any staking, they do not grow that tall and their stems tend to be relatively strong.
Anemone Coronaria Deadheading

Anemone Coronaria Propagation
The Anemone Coronaria can be propagated by dividing bulbs or by collecting seeds. This plant is extremely good at naturalizing, so even if you do not propagate it then they will still spread around. Once the plant is around 2-3 years old then it probably has made several smaller bulbs, just dig up the plant and divide the bulbs.
Anemone Coronaria Self Seeding
The Anemone Coronaria tends to self-seed, which is a big plus for some people but not all. In areas where it tends to do extremely well, it can self-seed like crazy, and keep in mind that this plant is considered to be invasive in many parts of the country.
