No. 4. Rosa moschàta, musk-scented, or white cluster, is an esteemed rose both for profusion of flower and agreeableness in fragrance. It is not of so rapid growth as the three previous, and may be kept as a bush; though it will grow to a considerable height if protected by a wall or close fence, being tacked thereto. Where kept as a bush, in very severe winters, it is the better of a slight covering, and is the latest flowering rose in the garden. The flowers are frequently on the same bush single, semi-double, and double, but mostly semi-double.
No. 5. Rosa moschàta supérba, or superb white cluster. This in habit and appearance is the same as No. 4, only the roses are double, and never vary; which makes it a very superior rose. It is highly esteemed and scarce.
No. 6. Rosa Aralie Noisettià. This has been called by some Purple Noisettià, (which is a very different rose, and not generally known.) In growth it is similar to No. 4, and could be kept in the same manner. The flowers are of a dark pink colour, very prolific, but not so large as No. 2.
These are all what are termed with us ever-blooming roses, being in flower from May until the buds are destroyed by frost. They should be pruned about the first of this month. The young wood is most productive of bloom; where the branches are too crowded, cut out the oldest wood as close to the ground as is practicable, and any of the dead branches. The shoots when tied to the trellis, arbour, wall, or fence, should be about six inches clear. The branches when made fast to their support ought to be in direct lines, which must at all times be strictly observed. It is very unsightly to see shoots trained crooked, or over each other, and, unsightly or unscientifical as it may be, it is too prevalent in every garden.
No. 7. R. Bourbòn is a double rose of brilliant red colour, petals large, stiff, and neatly set; the flower about the size of a common Provins rose, and finely scented; grows freely. The wood is strong, and undoubtedly it is the finest climbing rose that has come under our observation, and is highly admired.
No. 8. R. Boursault. This rose is much thought of in Europe. It is of a purple colour (and once called Purpurea), has a little fragrance, flower nearly the size of No. 7; wood more slender, and of very rapid growth, and capable of covering a large space. When in flower it is very showy. The old wood is of a purple colour. There is a white variety of it.
No. 9. R. Lisle, is of a light pink colour, about the shape and size of No. 8, grows freely, and flowers abundantly. This and No. 8. are the hardiest climbing roses that we know.
No. 10. R. microphylla. This rose is unique in every character, resembling No. 21. more than any other. The foliage is very small and neat, and the calyx thick and bristly. The flowers are produced at the extremity of the young shoots in twos or threes, according to the strength of the plant; they are large and double; the exterior petals large and full; those of the interior are very short and thick set; the colour in the centre is dark, shading lighter towards the exterior; the spines are in pairs on each side of the compound leaves. It is perfectly hardy, and greatly esteemed, and not so subject to be attacked by insects as other roses.
No. 11. R. Franklinia, or Cluster-tea, generally flowers well in May and June, but during the remainder of the season the heat appears to be too strong for it, the buds dropping off before expansion. The flower bud is larger than that of the Tea-rose; the petals large but loose, colour light blush.
No. 12. R. Bánksiæ, or Lady Banks' rose, is a free growing kind, and has a lucid green foliage; flowers small white clusters with pink centre, very double, and sweet scented; in bloom during May. From what we have seen of it, the spring months appear too changeable for perfecting all its bloom, many falling off from the chilliness of the nights. The plant naturally is an evergreen, but in our city is deciduous; grows best in sandy soil, and should be protected by mats during winter.
