A relatively compact alpine species with deeply cut, blue-green foliage and orange-yellow, and occasionally blue flowers, from July to September. Its native range is widespread, but mainly in the European mountains, such as the Alps and the Carpathians, and the northern parts of Asia but like many aconitum species, it has great variability, due to isolation and hybridisation. ...

This grand and imposing plant has stout stems which hold very late, August-September, spikes of rich violet-blue hooded flowers above rich green divided foliage. These are very valuable late season flowers when most else has gone. ... Learn More

This is the rarely-offered, very latest form of any of the "Monkshood" plants to flower here at Plant World. It's a cross between A. carmichaelii and A. carmichaelii var wilsonii and the long stems produce buds in August and September with the deepest inky blue flowers opening still later. These magnificent spikes of extraordinarily large flowers are only damaged by the first frosts in late October and November. ... Learn More

This quite unique herbaceous twining plant will climb to at least ten feet high, and bears from mid-summer to late autumn, long hanging clusters of ten or more large flowers. In addition to having attractive shining green foliage all season long, this selected form has intensely deep blue flowers. Very few good fertile seeds collected. ... Learn More

This rare and luscious parchment white form of Aconitum septentrionale is a superb variety with an erect bushy habit bearing clusters of ivory white hooded flowers on branching stems, with deeply fingered dark green glossy leaves which appear in early spring. It grows best in fertile, well-drained soil but should not be allowed to dry out if possible. Few seeds available. ... Learn More

Primrose-yellow, darker-anthered "monkshood" flowers open on short stems on this rare gem from the mountain slopes and forest margins of China, Korea and Eastern Russia. Very doubtfully in cultivation, it is a far superior plant to its relative, Aconitum lycoctonum, being shorter and more compact in stature, as well as having flowers which are outward-facing rather than pendent. ...

This virtually unknown, choice, and relatively dwarf species comes from the Altai Mountains of Siberia, where it grows at an altitude of over 7,000 ft. Making a large hardy tuber, it has dark green foliage, bearing in summer short stubby spikes of yellow-cream, monkshood blooms, each an inch or so across. ... Learn More

Green-lipped, palest yellow flowers open in early summer on this rarely-seen monkshood flower. A cousin to the more common Blue Monkshood, this species is not commonly seen in gardens, where it will form an upright clump of deeply-cut green leaves preferring a site that will not dry out. It also makes an outstanding cut flower. Like all monkshoods, all parts of this plant are poisonous. ... Learn More

Tall stems hold dense pyramids of narrow, hooded, ivory-green flowers, which are crowded up the stem. Dark green foliage resembles that of a delphinium, to which it related, and they are less cut than other species. This plant is a superb treasure for part shade, although it is happy in almost any aspect. ... Learn More

This is an unusual colour variant on the normal creamy-white form of Aconitum lycoctonum that bears strong spikes of purple-grey flowers shaded with cream at the mouth and dusky violet on the spur. As such it makes quite a change from the usual run-of-the-mill varieties. It is a local and regional Carpathian endemic from the nemoral belt of the mountains and taller hills. ... Learn More

Collected originally on our 2004 seed expedition to the Russian island of Sakhalin, ("Land of the Giants") this unusually large, and very lovely plant bears substantial rosettes of elegant ferny leaves from which arise tall, strong stems bearing whorls of sizeable, deepest blue "Monkshood" flowers. ...

We are offering a selection of a large number of different aconitums varying in colour from white and yellows up to pale lavender and deepest blue. All of them are hardy herbaceous plants, and habits vary from compact to bushy, with heights also covering a good variable range. Grow some and see if you can identify them, as we have collected too little seed to offer them individually. ... Learn More

An imposing specimen, forming an upright clump of deeply-cut green leaves, bearing tall, showy, strong, branching spikes of outward-facing, pale silvery-blue flowers. These are delicately-pencilled with deep blue in mid-summer, the effect being somewhat similar to delphinium, making it excellent as a cut flower. RHS AGM winner ... Learn More

Long-lived clumps produce very dense sprays of pale sulphur yellow hooded flowers in spring and early summer, above attractive, bright green shiny foliage. If dead-headed, flowering will continue into the autumn. ... Learn More
