Form: Half-hardy,
twining, climbing, of trailing, annual
Height: 6ft (2m) [Stems can trail 8ft
(2.5m)]
Spread:
Foliage:
Flowers: Dainty snapdragon-like flowers in
shades of red, pink, violet and blue, with speckled creamy lips, are
borne from spring and until the first frosts
Useful
for pots or hanging baskets, flowering from early summer to late winter
if protected from frost.
Sowing Instructions:
Sow from early February to mid April in a good seed compost just
covering the seed with a very thin layer of compost or vermiculite.
Germination takes 14-21 days at 65-70oF (18-20oC).
Don't exclude light, sealing in a polythene bag after sowing is helpful.
When large enough to
handle, transplant the seedlings into 3in (7.5cm) pots, and grow on in
cooler conditions, potting on as necessary. For outdoor planting,
gradually acclimatise to outdoor conditions and plant out in late spring
after all risk of frost has passed 12in (30cm) apart in a sun or shade
in a, sheltered spot and ordinary, cool moist yet well drained soil. On
acid soils, a dusting of lime is helpful before planting. Provide a
trellis, strings etc., for them to climb. They can be grown in a
greenhouse/conservatory and will need a final pot size of 7-8in
(18-20cm) and a minimum winter temperature of 41-45oF (5-7oC).

Form: Half-hardy,
non-climbing, perennial trailer
US Zones: 9 10
Height: 8in (20cm)
Spread:
Foliage:
Flowers: From early May until late autumn producing vibrant
cerise-purple antirrhinum-like flowers, clasped in lime-green bracts,

Ideal For: Hanging Baskets, Window Boxes, Patios,
and Tubs
Sowing
Instructions: Sow from early February to mid April in a good
seed compost just covering the seed with a thin layer of compost or
vermiculite. Germination takes 14-21 days at 70-75oF (20-24oC).
Seal in a polythene bag after sowing and don't exclude light.
When large enough to
handle, transplant the seedlings into 3in (7.5cm) pots, and grow on in
cooler conditions. When well rooted, plant into baskets or container,
using a good soil-less compost with some vermiculite added. Leave in a
shaded greenhouse for 2 weeks and then gradually acclimatise to outdoor
conditions for 10-15 days before moving outdoors, after all risk of
frost has passed, to a sunny, sheltered spot.
Water well and feed
once a week through the summer. To over-winter, bring indoors to a cool,
frost free place in autumn and keep just moist. For a windowsill pot
plant, grow on in a 5in (13cm) pot
