little to be done, this consisting principally of removing 

 and burning at once any leaf at all infested, and spraying 

 the remainder once a week for about three weeks with 

 Bordeaux mixture, which is a stronger remedy than 

 sulphur.

Hunnemannia fumarisefolia (the Mexican Poppy). — 



A graceful and beautiful flower, which should be seen 

 more frequently than at present. It is really a half-hardy 

 biennial plant, and is readily increased by seeds, which 

 may be sown in autumn when ripe, and as they often 

 remain dormant for some time, the soil must not be 

 thrown away under the belief that the seed has failed. 

 Select a very warm spot for this Poppywort, where the 

 soil is light, otherwise it will not succeed. The flowers 

 are very charming, clear yellow in colour, and the foliage 

 is pretty too. 



Hyacinth, The. — The garden Hyacinth of the present 

 day has for its progenitor Hyacinthus orientalis, a native 

 of Syria. The propagation of this bulb is now almost 

 entirely left to the Dutch growers, whose deep, sandy soil 

 is eminently adapted for its culture. New varieties are

raised from seed, and named kinds perpetuated by offsets. 

 The culture of the Hyacinth is exceedingly simple, as the 

 bulbs arrive in England containing the undeveloped 

 llower spike, which pushes up w hen the bulb is started 

 into growth. Hyacinth bulbs are often thrown awayafter 

 blooming in pots ; but if these are carefully knocked out, 

 without disturbing the soil, and the balls lowered into a 

 hole in the earth in a spare border, the soil being 

 subsequently made firm and a good watering given, they 

 will give pleasure for many a year, although the 

 spikes may not be as massive as on the first occasion of 

 their blooming. An out-of-the-way border filled in this 

 manner with some hundreds of discarded bulbs presents 

 a charming spring picture, and furnishes the house with 

 countless scented flower sprays. 



For pot culture single bulbs should be used in preference 

 to a greater number, as these seldom are at their best 

 simultaneously. They should be potted in three parts 

 fibrous loam and one part well-rotted manure, with a 

 sufficient admixture of silver sand to keep the compost 

 open. When potted they are best placed in a cold frame 

 and covered with a layer, din. to 6in. deep, of cocoa-nut 



fibre, being removed, when they start into growth, to a 

 light shelf in a cool house, and being placed, later on, if 

 it is desired to hasten their flowering, in a warmer 

 structure. 



The early Roman Hyacinth is particularly useful where 

 white flowers are required in the depth of winter. When 

 grown for cutting it is usually planted in boxes, but, 

 subjected to the same treatment as recommended for the 

 Dutch Hyacinths, it makes a pretty winter pot-plant. The 

 bulbs being smaller, three instead of one should be placed 

 in each pot. 



Of single Hyacinths the following named varieties 

 are good : White, alba maxima, Avalanche, Blancheur 

 a Merveille, La Grandesse, LTnnocence, Mont Blanc ; 

 blush white, Cloche, magnifique, Elfrida, Grandeur a 

 Merveille, Leviathan, Lord Shaftesbury, Mammoth ; 

 dark blue, Anna Bolena, General Havelock, King of 

 the Blacks, King of the Blues, Marie, William the First ; 

 light blue and porcelain, Amy, Czar Peter, Grand Lilas, 

 La Peyrouse, Queen of the Blues, Regulus ; red and 

 pink, Cavaignac, Circe, Cosmos, King of the Reds, La 

 Belle, Vuurbaak ; yellow, Anna Carolina, Bird of 

 Paradise, Grand Vedette, John Stuart Mill, King of the 

 Yellows, Obelisk. 



I )l double Hyacinths, the appended selection is com- 

 posed of handsome varieties : White, La Tour dAuvergne, 

 Grand Vainqueur, Prince of Waterloo, La Vestale, Lord 

 Derby, Princess Alice; blush white, La Virginite, Duchess 

 oi Bedford, Jenny Lind, Groot Voorst, Anna Maria, 

 Madame de Stael ; dark blue, Charles Dickens, Garrick, 

 Laurens Koster, Lord Wellington, Prince of Saxe- 

 Weimar, Bride of Lammermoor ; light blue and porcelain, 

 Bloksberg, Mignonnede Dryfhouts, Van Speyk, Magnifi- 

 cent, Delicata, Duke of Norfolk ; red and pink, Princess 

 Louise, Bouquet Tendre, Regina Victoria, Duke of 

 Albany, Marie de Medicis, Empress of India ; yellow, 

 Bouquet d'Orange, Goethe, William III., Croesus, Jaune 

 Supreme, Ophir. 



It is as well when ordering bulbs to specify the colour 

 required as well as the name, as often two differently 

 coloured varieties are advertised under the same name. 

 Thus, in taking up the catalogue of a noted bulb firm, one 

 finds that a double dark blue Hyacinth is named Charles 

 Dickens, and that the same title is applied to a single red 

 variety. Again there is a double blush Lord Wellington 

 as well as the double blue referred to in the preceding 

 list, while Princess Louise is advertised as a double 

 white as well as a double red, and this by first-class 

 firms. 



The only wild Hyacinth worthy of notice is H. amethys- 

 tinus, a native of the Pyrenees, which bears graceful 

 spikes of sky-blue bells. 

 Iberis.-- -The perennial Candytufts are of much beauty and 

 interest, forming dense green cushions pleasant to look 

 upon in winter, and smothered with white flowers in 

 summer. They should be planted so as to hang over 

 ledges or old walls, and here, the position being warm 

 and the soil light, the plants are more likely to weather 

 winter trials. The Iberises are not very hardy, being 

 extremely susceptible to damp. I. gibraltarica is 

 happier in a greenhouse or frame than on the open rock 

 garden. Indoors it will produce its white and lilac 

 flowers throughout the winter, and there is a variety of it 

 named hybrida which is worth growing. It grows about 

 lit. in height, and has bright green leaves, which are 

 almost hidden in the flowering season with very large 

 clusters of white or lilac blossom. When not grown in 

 the greenhouse the only position in which it may be 

 t usted is a warm, sunny nook where the soil is light 

 and moisture will run off" quickly. Damp, or anything 

 approaching stagnation, at the root is fatal. I. Printi 

 reminds one of I. gibraltarica, but is happily hardier, 

 and bears its pure white flowers in early summer. Plant 

 in an easterly position and in light soil. I. saxatilis is 

 quite dwarf, and has deep green leaves and pure white 

 flowers, and of this there is a very charming variety 

 named correaefolia, which may be planted as an edging 

 to walks. I. semperflorcns bears its sweetly-scented
