Clematis Indivisa.
This New Zealand variety of the Virgin's Bower does not appear to be sufficiently known nor is it cultivated to such an extent as its merits deserve.  For a cool house from which the frost is just excluded it is a most suitable climbing plant, being a fitting companion for such better-known subjects as the Lapagerias.  It can be adapted to various purposes to suit each respective case.  For instance, if a large break of bare wall in either a greenhouse or conservatory has to be covered, and that as speedily as possible, then this Clematis is well suited as one of the plants for the purpose.  It is well adapted also for training over wire arches of an ornamental character, also for running up the rafters or columns in large houses.  In whatever position it is grown, the young shoots should have a fair amount of freedom.  When covering a wall, for instance, as soon as the main shoots have reached their proper limits, then let the lateral growths hang down as a drapery; this will check over-vigorous shoots from gaining an ascendancy.  Upon arches the same plan should most decidedly be carried out, and again when training up rafters.  Not only is the growth itself rendered much more ornamental, but the appearance when in flower is greatly enhanced.  When trained closely, a large number of the blossoms must be hidden or so crowded together, as to spoil the effect as well as the lasting properties of the flowers by the accumulation of moisture.  Close training is also a greater encouragement to insect pests with the greater difficulty of reaching them in the process of extermination.  What pruning is necessary should be done immediately the plant is out of bloom and never during its period of growth; this latter plan means a proportionate decrease in the following crop of flowers.  If anything at such times is really found necessary in this way, it should merely be a thinning process where the shoots are too thick, removing those that are the least likely to produce flowers later on.  Insects, on the whole, are not troublesome, green-fly being the most likely to attack the points of the young shoots and thus cripple the tender foliage.  The flowering season is from April to May, when a beautiful effect is produced for a long time by reason of the freedom, the succession, and the lasting properties of the blossoms.  This Clematis cannot in any sense be considered a difficult plant to cultivate; it is of good constitution, and not over-particular as to the soil into which it is planted.  I would, however, choose this as good as possible with a view to lasting properties.  Fibrous loam with some well-decomposed leaf soil would suit it well, only using peat when the latter fails to be of good quality.  Planting out is preferable to either pots or boxes, for the greater the freedom the roots have the better will be the ultimate results.  Whilst in flower and during growth the supply of water should be liberal, but if a late growth in the autumn is apparent, then withdraw the water as a check to the same, such wood not having any chance to become well ripened.  Although this Clematis is seen at its best as a climber, it does not follow that it is not adapted to pot culture.  Only at the last Crystal Palace spring show there was an excellent illustration of this method in the beautifully flowered examples in quite small pots.  These little plants bore their blossoms in profusion, causing a large amount of attraction both by their pleasing creamy white colour and their simplicity.  For decorative uses, therefore, in pots it is likewise to be recommended.  In the most favoured parts of the country it will, with ordinary precautions, without doubt resist our English winters if upon walls.  It must not be confounded with another kind known by the varietal name of C. indivisa lobata, which differs slightly in its foliage, but more so in its shyness of flowering, being sometimes disappointing in this respect as compared with the type, of which an excellent illustration is now given showing one of its many uses.  —Plantsman.

Clematis Indivisa. Willd. — Annales de Gand, 1842. 61.
Cette espèce à fleurs blanches est inférieure et est moins recherchée que le Clematis indivisa lobata Hook.
Le Clematis indivisa, Willd., est originaire de la Nouvelle-Zélande; il a été découvert et décrit déjà, par Forster, vers 1798; puis retrouvé et rapporté plus récemment en Europe par le rév. William Colenso, en 1843 ; ce missionnaire, zélé botaniste, en envoya des graines au jardin botanique de Kew (Angleterre).
