If you're never sure what colour mixes look great in baskets and containers, or are uncertain about which varieties can be grown together these Trixi Romance Plugs are perfect for you. Each single plug contains 3 separate complementary varieties grown together of petunia, lobelia and bacopa, in soft pastel hues of pinks and purples. The result is an instant high-quality and colourful display in the perfect colour combination. We would recommend using 1 to 3 plugs per 30cm hanging basket or container
