Lobelia cardinalis 'Queen Victoria'
A summer spike of brilliant-red, three-lobed flowers above almost-black leaves smoulders in hot sun - use with tropical moisture lovers like cannas and hedychiums
- Position: full sun or partial shade
- Soil: deep, fertile, moist soil
- Rate of growth: average
- Flowering period: August to October
- Hardiness: fully hardy
Stunning spikes of scarlet, five-petalled flowers rise up in late summer among beautiful, beetroot-coloured foliage. This gorgeous cardinal flower brings a splash of vibrant colour to the garden just as many perennials are fading. It is excellent for filling gaps left by early-flowering perennials in a mixed or herbaceous border and suits a planting scheme based on 'hot' colours.
- Garden care: Divide large clumps of plants every second year in spring. Protect the crown of the plant during winter with a thick, dry mulch, such as straw. This moisture-loving plant can also be grown at the edges of a pond, and will tolerate water levels up to 30cm deep if potted up it into a basket with aquatic compost.
- Harmful if eaten

You can cut the stems down to just above ground level after they have died back, but immediately after you should apply a generous layer of mulch to help protect the crown.Answered on 10/2/2013 by Helen from Crocus
Tender perennials, such as pelargoniums, fuchsias, osteospermums and marguerites look great all summer, but unless they are given protection from the harsh winter weather, they will need to be replaced each spring. If you can do this, they will last for yRead full article
