Dianthus 'Blackjack'

Carnation

New modern cut-flower quality carnation plants packing the heavenly scent of antique varieties! Modern breeding work has seen the unmistakable scent of carnations all but disappear in the search for longer, cut flower-quality stems. Fortunately Carnation 'Blackjack' bucks that trend. Not only does it offer a unique colour combination, the near black blooms also bring punchy clove-like fragrance to the garden. A perfect border carnation, it also performs well in containers. Originally planned for the commercial cut flower market, you won't be disappointed by the endless supply of fresh stems either! Keep the colour and scent in the garden or use Dianthus 'Blackjack' as your very own cut flower carnation. Height and spread: 50cm (20").


Culinary note: Use the clove like tasting petals for adding to cakes, either for flavour or decorating, suitable for soups, salads and sauces too. For more details about edible flowers click here.

Pelargonium, Pelargonium 'Penevro', Ivy-leaved Geranium, Ivy-leaved Pelargonium

Although technically perennial, Pelargoniums are only half hardy and therefore normally treated as annuals in the UK. However, with care, they may be overwintered in a frost free greenhouse.
