Wallflower Ruby Gem
This gorgeous wallflower is a deep ruby colour and produces clusters of fragrant blossoms on sturdy stalks. Each flower head is composed of a large number of separate blossoms, which contributes to the overall attractiveness of the flowers. Early in the year, at the same time when tulips are coming into bloom (March through May), blooms are produced on this plant. Ruby Gem has dark buds that open to reveal magnificent flowers that range from brilliant crimson to violet. They are attractive as a cut flower in addition to being very useful in the garden, where they can be planted in a border with tulips and other spring flowers like forget-me-nots.
The finest results can be achieved by cultivating these in a row in the cutting patch, as bedding plants, or in bold groupings in a mixed border when they are exposed to direct sunlight. All wallflowers are quite simple to cultivate and very productive, meaning that you will get a lot of flowers for a relatively small investment of time, money, and effort.
