Helianthus x multiflorus 'Flore Pleno' is a robust, perennial plant that produces double yellow flowers throughout the summer. Its deep green foliage is an excellent screen or foil to showcase small plants. Flowers of Helianthus x mult. 'Flore Pleno' are scattered all throughout this "green wall" which makes it an excellent choice for the back of your border.
This is a good plant for cut flowers and blooms for 4 weeks or more. It can be planted in containers and attracts butterflies. Prefers average, neutral to slightly alkaline soil. Well drained soil is good for overwintering, but give Helianthus a good soaking if August begins to overpower. Can be divided in spring every 3-4 years. Cut back by one-half in early to midsummer to prevent staking.
