Wallflower is a genus of attractive herbaceous plants which are rated as biennials, annuals or short-lived woody-based perennials. It belongs to the same family of cruciferous vegetables as cabbage, cauliflower or broccoli (brassicaceae), but it is not meant to be eaten – only to be looked at and admired which puzzles me a little when it comes to its common name. Wallflower is native to southern Europe, northern Africa, western and central Asia and North America. In modern horticulture the varieties that are most often cultivated are those that arose from the crossing of e. cheiri and e. linifolium. They stand out with colorful flowers and some even with a sweet, violet-like scent.

Red Jep is a wallflower variety with red flowers. They are a rich and warm shade of blood orange as they open, and fade to pale purple to pastel violet magenta as they mature. They bloom from the first truly warm days of spring and bloom until the end of summer. New buds are formed repeatedly atop bare, leafless stems which can grow to a height of around 50 cm by the end of the growing season. If you don't like the overgrown stems, you can remove them in midsummer and the plant will produce new stems with fresh buds from inside the clump. The leaves are narrowly lanceolate to oblong, medium green and evergreen in mild winters. The entire clump with leaves is dense and compact and can triple in size in one year.

During flowering, you can gently fertilize the plant with organic fertilizers. Excess feeding will result in bombastic flowering but will exhaust the plant so much that it will very likely not survive the winter. It has to be said that wallflower is short-lived as a perennial. Nevertheless, it enjoys increasing popularity, because if you plant it in suitable conditions, even the few years that it lasts in the flower bed will delight you with its long-lasting flowering period like few other perennials.

Wallflower loves full sun and free-draining, preferably alkaline or neutral, less fertile to poor soil. In cold regions, cover the plant with fir branches for the winter to prevent the roots from getting wet with snow and to protect it from hard frost. Hardiness varies a lot and is most often rated around -21 °C (USDA zone 6).

  • STANDARD QUALITY - Plants of this group are 1st class quality with number of branches and overall density adequate to their size and age, considering they were container grown.
  • DE LUXE QUALITY - This label guarantees a luxurious quality of manually selected plants that, compared to their height and age, are exceptionally dense and beautiful.
  • EXTRA - These plants are usually mature and bigger specimens with exceptional overall appearance.
  • STANDARD (as described in the plant form) means a tree with a trunk of 190-210 cm and a crown at the top, unless specified differently. The commercial size for trees is their girth measured in the height of 1m from ground.
  • HOBBY - These plants are of the same quality as our standard-quality plants but younger and therefore cheaper.
  • SHRUB - a woody plant with branches growing bushy from the ground level.
  • HALF-STANDARD or MINI-STANDARD - a small tree with shorter trunk, its size is usually specified.
  • FEATHERED - These are trees with branches growing already from the base of the trunk and up along the stem.
  • GRASSES and PERENNIALS - Sizes given usually read the diameter of the pot or the clump, as specified.
