straggly growth iits it admirably for massing 

 with other flowers, as it will thrust its heads 

 of lovely white, tube-shaped, fragrant flowers 

 between the branches of other plants and is 

 not, therefore, easily obscured. N. Sylvestris 

 is not a night bloomer, strictly speaking, as its 

 flowers are also open in the day, but it makes, 

 from the robust freedom of its growth, often 

 exceeding six feet in height, an admirable 

 center for beds of lower growing varieties, 

 and may be massed with N. affinis and brug- 

 mansias, with excellent effect. The dwarf 

 growing four o'clocks may be used for a 

 border for beds of the taller plants and in the 

 mathiola, or evening scented stock, a sweet 

 and penetrating fragrance is assured. 



Who of us have not, in childhood's days, 

 watched in vain for the opening of the cups 

 of the evening primrose — those pale yellow, 

 tantalizing things, and who of us were ever 

 able to boast that we had really seen it done? 

 What was the magic that always tempted our 

 eyes to roam at just the critical moment? 

 Only the moths and the firefly know the 

 secret of their opening. 



The night garden may be divided from the 

 garden proper by an arch over which the 

 moon flower climbs and blossoms, or a sum- 

 merhouse draped with its heart-shaped leaves 

 and snowy blossoms may give upon the garden 

 that wooes the moth and the night. It may be 

 used to clamber over the pillars of the pergola 

 where the path to the garden strays, or 

 mask a wall that screens the garden by day 

 from the too prying eye of man and leaves it 

 in sweet seclusion to the bee and bird. 



The moonflower, as indeed all the night- 

 blooming flowers, may be easily raised from 

 seed ; but as the seeds of this especial plant are 

 hard and slow to germinate, they should be 

 forwarded by soaking in hot water over night, 

 first removing a portion of the outer husk, till 

 the white show's through, and then planted 

 in small pots of earth in the house or hotbed. 

 This should be, if plants for this year's bloom- 

 ing are wanted, not later than the middle of 

 February. As soon as the plants are up and 

 growing and the small pots filled with earth, 

 they should be shifted into larger pots of 

 somewhat richer earth and encouraged to 

 make as rapid growth as possible. 



In shifting the plants from the smaller to 

 the larger pots, care must be taken not to 

 disturb the roots or break the ball of earth. 

 The best manner of transplanting is to take 

 a pot of a larger size and place a little drain- 

 age material in the bottom and a small amount 

 of earth — about what will be needed to fill in 

 the space between the ball of earth in the 

 smaller pot and this. Work this earth well up 

 around the sides of the pot and press the 

 smaller pot into it to shape it. Slip the ball 

 of earth out of the pot by tapping the pot on 

 the edge of the bench to loosen it when it may 

 be turned out on the hand and slipped into 

 place in the new pot without the least dis- 

 turbance. Moonflowers should not be plant- 

 ed out in the open ground until all danger of 

 frost is passed and the nights and ground are 

 w : arm. 



The tropical waterlilies afford some de- 

 lightful examples of night bloom and if to 

 the charm of the garden may also be added 

 that of water and moonlight on the shimmer- 

 ing lily pads the night-blooming garden will 

 be a joy indeed.
