gentle hotbeds; shading, spraying, and later on airing, 

 must be strictly attended to. Layering is practiced 

 where large old stools are at hand. The knife is not used 

 in the operation, but a twist of the stem will split the 

 inner bark lengthwise. Every other joint is thus treated, 

 pegged down, and covered with soil. It is best to leave 

 the layers undisturbed until the following spring. Many 

 of the species are often propagated by seed, and many 

 new varieties have thus been formed. The number of 

 hybrids is almost countless ; in this account are care- 

 fully recorded all those in the American trade which are 

 traceable to their origin. 



The Clematis is subject to a very serious disease, due 

 to the depredations of a nematode worm in the roots. 

 This trouble is most serious under glass and alongside 

 buildings where the ground does not freeze deep. The 

 parasite is probably distributed in the soil a<lhering to 

 pot-grown plants. It is probable that hard freezing kills 

 the parasite. There is no remedy, so far as known, for 

 affected plants. Using only soil which has been frozen is 

 to be recommended to the propagator. jf . C. Davis. 



The hybrid varieties of Clematis, commonly known as 

 the large-flowering sorts, are, when successfully grown, 

 among the most beautiful of hardy climbing plants. The 

 commercial propagation and growing of most of the 

 large-flowering varieties, however, is attended with so 

 many difficulties and disrippnintmnnts that it has never 

 been very generally attmipf,,! ),y nursiryinen or florists

 propagation of Cl'iiuiti- tu :iny L-uiisidtrable extent, and 

 it is only within the past fifteen years that Clematises 

 have been commercially grown even by this limited 

 number. Prior to that, practically all of the large-flower- 

 ing Clematis planted in this country were imported from 

 Europe, the in.ijcr ].art being supplied by Holland,

 entirely dill. r. nt fn.iii those usually found in this 

 country that the plants often failed to adapt themselves 

 to their new surroundings, and did not thrive to the ex- 

 tent that their good size and vigorous condition seemed 

 to give promise. 



The propagation of Clematis throughout Europe is 

 ustially effected by grafting pieces of well-ripened, year- 

 old wood upon roots of almost any of the more vigorous 

 growing species, Clematis Flamniula being most com- 

 monly used. In this country, on the contrary, the method 

 commonly pursued is by means of cuttings from young 

 wood, struck in sand, with gentle bottom heat, usually 

 during May or June. So far as concerns the comparative 

 vigor and desirability of

sential characteristics, — vigorous habit of growth and 

 abundance of bloom. Olfin'ilis Jurkma tii, purple, 

 originated in 1862, by Mr. (i.-cir-. .la.knian. was one of 

 the first hybrid Clematises iiitn.ilur, a, ^nnl .-till stands 

 as the most popular, and, of its .-.ilor. tin- most valuable 

 variety yet known. The new variety, Madame Edouard 

 Andr^, a deep, rich crimson, is distinct and novel, being 

 at this time the only large-flowering sort of a truly 

 crimson shade. It is of fully as vigorous habit as the 

 Jackmani, and its flowers are similarly massed, though 

 not produced in quite such profusion. Clematis Madame 

 Baron Veillard is another new and distinct variety that 

 promises to prove a valuable acquisition. It is of ex- 

 ceedingly vigorous habit, and the flowers are quite 

 freely produced, though, being more dispersed over the 

 plant, they do not make so much of a show as do varie- 

 ties whose flowers are closely massed. The flowers are 

 of very large size and of a light rose color, shaded with 

 lilac. Of white varieties, Henryl, Mrs. George Jack- 

 man and Lanuginosa Candida, all of them introduced 

 long ago, still remain about the most desirable ones 

 known. Bamona, deep sky-blue, is a variety which 

 originated on our grounds some ten years ago. " It is of 

 extra large size, often 9 to 10 inches across, of very 

 vigorous habit and free-flowering.

 Veitch is a double sort with flowers of lavendir-blue,

 India (purple), Velutine Purpurea (purple), and V'iti- 

 cella Venosa ( reddish purple ) , are all desirable varieties. 



Although they are in reality slightly less hardy than 

 the Florida and Patens types, we would recommend for 

 northern localities varieties of the Lanuginosa, Viticella 

 and Jackmani types, which produce their flowers from 

 young growing wood. Plants of these tjTies, even if 

 frozen back to the ground, will still produce a good show 

 of flowers, since, as stated, they bloom from the young 

 growing wood. Indeed, they need to be pruned back 

 considerably anyway to induce a free growth of young 

 wood. With plants of the Patens and Florida types, 

 which blossom from year-old wood, a severe freezing 

 back of the plants would destroy the crop of flowers for 

 the year.
