Although Cymbalaria plants are half hardy perennials, these ivies are normally grown as half hardy annuals by gardeners.
They are low growing and love to grow in walls and rock crevices.

If you are planting members of the Cymbalaria genus such as Kenilworth Ivy and Ivy Leaved Toadflax from seed outdoors, then they should be sown on the soil surface after the last frost of spring.
They like to grow in sunny areas, but benefit greatly from receiving shade in very hot areas.
Cymbalaria like to grow in moist soil that has a somewhat alkaline pH.
Seedlings of Kenilworth Ivy, and other Cymbalaria species, can be started early by growing from seed indoors first.
They should be started off about 10 weeks before you plant them out, following the last frost of spring.
They normally take about two to four weeks to germinate in the light, at a temperature of 15 to 18 degrees Celsius (59 to 64°F).
Once the Cymbalaria seedlings are ready, they should be transplanted outside with a spacing of about 15 cm (6 inches).
These ivies take very little looking after. They should be watered regularly, and cut back and dead headed before any chance of setting seed, to help prevent them from taking over the garden.
