Description of the plant:
In a world of sea hollies TTiny Jackpot is exactly what its name says. It is tiny and as great as a jackpot you’ve just won. This dwarf sea holly makes short, extremely well-branched, and compact plants producing prickly flower-heads decorated with narrow bracts at the bottom. They are extremely colourful and exotic once they have matured to their typical colour. They come out in late June atop some 30 cm tall stems and gain the typical steel blue shade only after about a month but remain blue over a long period without fading, even when the flower-heads have dried completely. These plants are ideal for drying and using in various decorations in autumn or winter. Cut them off when they show the best colour and hang them upside down in a dark, warm place.
Sea holly needs free draining soil and full sun. It will thrive in poor, sandy loam, at the edge of a sunny perennial border or a rockery, and will look great in a small container on a patio. Fertilizing is not necessary. Very hardy to about -45 °C (USDA zone 2).
