Anemone-De Caen

Are you looking for a beautiful summer cut flower or bulb plant that will force well indoors, during the winter? Look no further than the Anemone 'De Caen'. The Anemone is also known as the 'windflower', as the large petals catch the slightest breeze and pivot left to right on its long thick stems. The blooms are always a colorful surprise when planted in groups in the flower garden. In the garden they bloom for several months and as a cut flower the individual stems will last for 7 to 10 days. Plant the bulbs in a rich soil with a lot of organic matter such as compost and manure. The bulbs will do best in a sunny and warm spot in a pot or directly in the garden. If you're planting in your garden start plants indoor for early color in the garden. Direct plant in May in most cold climates and dig up in the fall after a frost has put the plant to rest for the winter. The bulb or corns are not winter hardy in the northern states. The flower grows 12 inches tall and you should space the bulbs 6 inches apart in the garden. Plant in September for a great potted winter flowering plant.
