![]() ![]() Our nursery, situated in the North of Dorset close to the Somerset border, is full of the plants we love. Links Scabious Compared Botanical Style Photographs (Scabiosa) Botanical Style Photographs (Succisa / Succisella)Īt Dorset Perennials you will find a husband and wife team, Dawn and Martin, who have been plantsmen and nurserymen for nearly 25 years. The numbers plants use are those on the Fibonacci sequence – Plants really can count. Plants always have the same number of petals in their flowers. Furthermore, it is not the only place you can find the Fibonacci sequence in plants. This is an adaptation that allows the most flowers to fit in a given space with the least gap. (ie 1,1,2,3,5,8,13,21,34 a sequence made up by adding the previous number each time). What is fascinating about these spirals is that the number of spirals each direction will be different and they will be found to be two adjacent numbers on the Fibonacci sequence. ![]() It is a characteristic that shows up better in some species than others. If you look closely at the unopened flower you can see that the individual florets arrange themselves in two spirals, one to the right and one to the left. The flowers of Cephalaria, Knautia, Succisa and Succisella all follow a similar pattern, each with a decreasing emphasis on the large outer flowers. The often contrasting colours of each flower type and the colours of the stamens and pistil are what make theses flowers so attractive. This gives the flower its pincushion form. Within the disc, the male stamens are held close to the flowers throat whilst the female pistil projects well out. All are basically trumpet like tubes, its just that the outer ones develop more colour and have much more flamboyant petals. The flowers making up the central disc florets and those more showy outer ray florets are essentially the same. A tight dome of individual florets makes up the central disc. Each individual flower head is in fact a compound flower just like the daisies. I thought I would write a small piece on the intricate flower structure that scabious exhibit with the tight pincushion centre and flamboyant outer petals. An easily grown and rewarding plant for full sun. the foliage is generously variegated such that the stem leaves are nearly completely cream. Instead Knautia macedonica ‘Thunder and Lightning’ is quite compact and a good deal shorter at 30-45cm. This new variant on Knautia departs somewhat from the light and airy cloud of the species. Classification of the Plant Kingdom ( some of it anyway !)ĭescription Knautia macedonica ‘Thunder and Lightning’.They are designed to give you an overview of how different plants are related. Pages arranged along Taxonomic lines Each page covers one Order (the level above Family) and lists all of the Families within that Order and then the contained Genera within that.
