Best of the bunch
●● Bacopa
This effective trailing perennial, often grown as an annual in this country, combines well with almost any colour scheme, its tiny white flowers draped over window boxes or spilling out of containers and cascading over hanging baskets. You can also grow mauve varieties and it spreads quite effectively in containers so is great as a fill-in.
It will do well in sun or light shade in multi-purpose compost, but keep it well watered throughout the summer months, trim and feed it occasionally to keep it going. Good varieties include B. ‘Snowflake’ and B. ‘Snowtopia’.
