The bulbs are of easy culture. After blooming, and the foliage fully grown, they should be allowed to rest for several months, then start into growth by watering sparingly until the flower stalks appear, when a more liberal supply should be given. Usually two successions of bloom can thus be obtained. The bulb should be planted so as to leave the upper portion uncovered.
HOYA CARNOSA, OR WAX PLANT.
This plant is a native of tropical Asia, where it is partially parasitical, its roots penetrating the bark of the trees which support it. It was introduced into England in 1802. There are several species, but only one is generally cultivated. Hoya Carnosa has thick waxy leaves, and bears umbels of beautiful flesh-colored flowers which are very wax-like in appearance. It is an excellent plant for house culture as it stands the extremes of heat and cold better than most plants, and is not easily injured by neglect. It can be trained to climb on trellis-work to almost any height, and when in bloom, which continues for half the year, it is a very interesting plant.
There are several varieties of Hoya, but one only is generally cultivated. Silver Variegated Foliage is said to be very handsome but is of slow growth and difficult to propagate. Imperialis is a new variety with beautiful foliage and scarlet flowers. Cunningham has light green leaves, deeper colored flowers than the Carnosa and is a rapid grower.
They succeed best in peat, with some fibrous soil and sand. They must have perfect drainage, and require a period of rest. Hoya Carnosa is easily propagated from cuttings. A very good method is to wrap a cutting in moss, keeping it moist until the roots are well started.
AUGUST is the month when we rest from our labor in gardening, and abandon ourselves to the full enjoyment of the varied blossoms which so abundantly meet our eye. Now we can best determine what changes may be required in the arrangement of our plants next year, in order to give the most pleasing effect. A tall plant may have been inadvertently set out in the midst of those of low growth, and we see now how awkward it looks. Short-lived annuals may have occupied a conspicuous place, and on their departure left an unseemly vacancy. A bed may have been filled with a class of plants that are not free bloomers, and so there has been little beside leaves, while another bed has been brilliant during all the summer months with flowers. Annuals of a new kind, high-priced novelties, have been tested; are they any better than our old favorites? If we cannot indulge in many sorts, what do we find the most satisfactory? Twenty-five cents per packet seemed very expensive for Heddewigii Pinks, but Crimson Belle and Eastern Queen are of such superior size and rare beauty that the investment is not regretted, and then we know that they will bloom in greater perfection next year, and that the seed saved this autumn and sown in early spring, will increase the stock. Twenty-five cents for a paper of Candytuft seed looks extravagant, but no one who invests in Tom Thumb would regret it. It is so dwarf, so compact and bushy, such a long continued bloomer, so admirable for edging a bed, that it is really almost an essential. Then it will sow itself, and the seedlings will be up as soon as the frost is out of the ground, and plants from self-sown seed are so much more thrifty and early than those one sows in the spring, that this is a great gain.
