Moraea Iridioides.—­These plants flower in May, and require the same treatment as Ixias.

Morina (Whorl Flower).—­An ornamental hardy perennial, which is seldom met with.  It forms rosettes of large, deep green, shiny foliage and stout spikes of rose-coloured flowers in whorls, which make it one of the most attractive of Thistles.  It likes a rich, light soil, is increased by seed sown in the autumn, also by division in August, and flowers in July.  Height, 21/2 ft.

Morisia Hypogaea.—­This is a pretty hardy perennial for rock-work.  It flowers in May, and is raised from seed sown as soon as it is ripe.  Height, 2 in.

Morna Elegans.—­Beautiful half-hardy annuals.  For early flowering sow the seed in September:  for later blooms sow in February in slight heat, pot off, affording good drainage to the plants.  They are very sensitive to cold, and should not be placed out of doors before the end of May.  Avoid over-watering, as this would prove fatal to them.  The soil should be light and sandy.  Those sown in September will bloom in the greenhouse in May; those sown in February will flower in the open in the autumn.  Height, 11/2 ft.

Morning Glory.—­See “Convolvulus.”

Morrenia Odorata.—­A good twining plant for the greenhouse, producing fragrant cream-coloured flowers in July.  It will grow in any good loamy soil, and may be increased by cuttings.  Height, 3 ft.

Moss.—­To eradicate moss from fruit-trees wash the branches with strong brine or lime water.  If it makes its appearance on the lawn, the first thing to do is to ensure a good drainage to the ground, rake the moss out, and apply nitrate of soda at the rate of 1 cwt. to the half-acre, then go over the grass with a heavy roller.  Should moss give trouble by growing on gravel paths, sprinkle the ground with salt in damp weather.

Mountain Avens.—­See “Dryas.”

Muhlenbeckia Complexa.—­A very decorative climber, hardy in nature but requiring a good amount of sunshine to make it bloom.  A well-drained, sandy soil is best for its growth, and it can be increased by cuttings of hardy shoots taken early in summer.  Height, 6 ft.

Mulberries.—­Any good soil will grow the Mulberry.  The tree is hardy, but the fruit wants plenty of sunshine to bring it to perfection.  It may be propagated by cuttings of wood one year old with a heel two years old attached.  The only pruning necessary is to keep the branches well balanced.  Autumn is the time to do this, not forgetting that the fruit is borne on the young wood.  When grown in tubs or large pots in the greenhouse the fruit attains the perfection of flavour.  In addition to the Large Black and the White (Morus Alba) the New Weeping Russian White may be recommended.

Mulching.—­See “Soil.”

Muscari.—­See “Hyacinthus.”

Muscari Botryoides.—­See “Hyacinthus.”
