  • Violet and lime green dusts (EdAble Art)
  • Amethyst dust (Cake&Cake)
  • 100g white and green gumpaste
  • Semolina

1. Lightly colour a small amount of white edible gumpaste by mixing in plum and violet dusts. Make a small shape as shown out of a small sausage. 

2. Press it into the mould trying not to reach the edges. Flex the mould and release.

3. Frill the edges of the flower with a toothpick.

4. Slide a very small ball of light green paste down the 28 gauge wire. Tape five micro stamens using 1/4 width of white floral tape.

5. Dust the stamens and the stigma lime green. Colour some semolina lemon yellow. With a very thin paintbrush, spread a little edible glue on the anthers and dip them in the semolina. Let it dry completely before assembling the flower.

6. Add the stigma and the stamens to the flower and let it dry upside down. Finally, dust the centre of the petals first with plum, then violet and then with amethyst.

7. Roll out a small amount of light green paste and cut the calyx using the mould. Soften the calyx edges with a ball tool. Dust the calyx mixing foliage green and autumn gold dusts.

8. Brush a little edible glue at the base of the wild petunia and attach the calyx. Make eight wild petunias in total.

9. Make a sausage shape with the light green paste. Roll over the paste with a small rolling pin and on a Celboard. Cut two small leaves with the cutter. Insert a white 28 gauge floral wire. Put the leaves on a CelPad and roll their edges with the ball tool.

10. Repeat step 9 for three more, bigger leaves.

11. When the leaves are dry, dust them by mixing foliage green and autumn gold, then their edges with burgundy. Glaze them too.

12. Cut a 20 gauge wire into two parts and twist half width pale green floral tape around the two wires.

13. With half width pale green floral tape, assemble the leaves and petunias around the two 20 gauge wires. Dust the floral tape with foliage green and plum.

Top tip! Dust your wild petunias when they're not completely dry and always remove the excess dust from your brushes on a piece of absorbent paper. You'll avoid spoiling your flowers with too much colour.
