Two worlds meet... Coselja is a cross between a European and a Japanese Matthiola type. This results in a class of its own with darker green, more oval shaped leaves and somewhat larger flowers. The stems are longer, somewhat woodier and more robust, which ensures an excellent vase life. Matthiola Coselja Lavender produces light violet blue/lavender coloured flower spikes with a sweet fragrance. You plant the Coselja series in winter until late spring for top quality from spring to summer. No fuss or extra work. The Matthiola Coselja series is easy to select for doubleness after a cold treatment, so you will start with an excellent series with 100% double flowers.
