The only half-hardy variety that need be referred to is Sutton’s Pot Myosotis, which is a delightful subject for flowering indoors at Christmas time; and as Forget-me-nots are everywhere welcome, the practice of growing plants in pots is rapidly increasing.  Seed should be sown in a cold frame in June, and the seedlings can be potted on as required, taking care from the commencement to avoid crowding as a precaution against mildew, to which the plants are very liable.  The strain referred to produces fine free-growing specimen plants, and a batch should always be in reserve for cutting.  For table decoration in winter Forget-me-nots are very telling.

All the hardy varieties may be sown from May to July for a brilliant display in the following spring.  The seed should be put into a prepared seed-bed under the shelter of a wall or hedge; and in autumn the plants must be transferred to blooming quarters at the earliest opportunity.

Myosotis make an extremely effective groundwork for spring bulbs, for which purpose =M. dissitiflora= is the most valuable.

==Nemesia STRUMOSA Suttoni==

==Half-hardy annual==

This beautiful South African annual is remarkable for its floriferous character, long duration of bloom, and diversity of colour.  Since we introduced it to this country in 1888 it has attained great popularity as a pot plant for table decoration, and some of the most resplendent bedding effects in public parks and gardens have been secured with this flower.

For an early show of bloom sow in pots or pans in March under glass, using a compost consisting largely of good fibrous loam, with the addition of a small proportion of wood ashes.  No more heat than necessary should be used, and when the seedlings are large enough to handle prick them off and gradually harden for planting out in May.  Other sowings may be made in May and June, and at this period of the year the seed germinates most quickly in boxes placed in a cool shady spot out of doors.  In early summer seed may also be sown in the open border, and by thinning to a distance of six or eight inches sturdy plants will be secured, which will remain in bloom until quite late in autumn.

For winter and early spring flowering in pots seed should be sown in August or September.  There must be no attempt at forcing, or attenuated worthless plants will result.  A further sowing may be made in January for blooming in the later spring months.

Like the seed of Verbena, Furze, and some other subjects, the germination of Nemesia under artificial conditions is somewhat capricious, but no difficulty will be experienced with open-air sowings.

==Tobacco.  Half-hardy annual==

The delicious fragrance of the Tobacco plant, especially during the morning and evening, has made it a great favourite in the greenhouse and conservatory, as well as in beds and borders near frequented paths.
