C. stellata can be used where tall plants are r<: quired. The most popular types are strains of C. multiflora nana, which are dwarf and compact.
Sow in April for November and December flowering, or in June for a January and February, and July for late spring flowering. Sow thinly in or trays at a temperature of 13°C. Seed is very small and needs only to be barely covered.
J.I. Seed, or peat/sand mixes may be used.
When thehave germinated and plants have two pairs of rough they should be potted off into 75mm, . J.I.P.l. may be used, or a mixture of 2 parts sandy loam, 1 part peat, and 1 part grit, or a loamless mix. A sharply drained compost is essential for Cinerarias.
When the young plants have filled their pots, they should be potted on into 125mm pots, using J.I.P.2 compost or loamless equivalent. Any sucker type growths should be removed, andcan be commenced using dried blood and sulphate of potash, in equal parts, or proprietary liquid feeds. Aim at a temperature of 13 – 15°C.
Plants being raised in the summer months can be transferred to cold frames. Some light shading is necessary, also adequate ventilation. Before cold weather starts the plants should be taken out of the frames and placed in a cool glasshouse with a night temperature of 8 -10°C.
Although close attention tois needed, over- must be avoided as will be damaged and plants will flag (as if dry).
Brief details ofof some of the commonly grown plants are as follows:-
C. comosum variegatum. This produces small(from the flowering spikes) which can be inserted as . Also C. capense variegatum – very similar with the variegation the reverse of C. comosum variegatum. Established plants can be divided in March – April.
decora is one of the most popular house plant subjects. Propagation is by bud cuttings, or ends of shoots can be used as cuttings, but this gives less material.
Propagation is by cuttings 100 – 150mm long which need bottom heat and a temperature of 20 – 23°C for best rooting results. Rooted cuttings are moved on in 75mm, and later 125mm pots in J.I.P.I. or peat and sand composts.
Several varieties are grown as house plants and H. Helix Chicago and its variegated form, H. canadensis are popular. Propagation is by leaf bud cuttings which are prepared bya into pieces, each with a leaf and small portion of above and below the bud. Cuttings are inserted in a sandy compost, or half sand and half peat, in trays in a propagating frame and potted up into 75mm pots in J.I.P.I. when rooted. Variegated varieties are slower to . Usually 3 or 4 plants are potted together to make up the plant as it is sold.
S. trifasciata. This is another popular subject, although slow growing. The green leaf variety can be propagated by. The variegated variety must be propagated by suckers, otherwise it reverts to green. A temperature of 18°C is needed in the stages and 15°C later.
T. fluminensis variegata is generally grown and sold in 75mm, or 90mm pots. Cuttings root readily and 3 or 4 are inserted around the edges of a pot and are grown on in the same pots.
