- Sow seeds indoors between Feb-Apr or direct sow outdoors after danger of frost has passed.

- For bushier growth, pinch back young plants.

Zinnia ‘Oklahoma Mix’ is a popular blend that produces masses of fully double blooms in a wide range of bright colours on long, sturdy stems. It flowers continuously throughout the summer and is less susceptible to powdery mildew than other varieties. It’s been awarded the RHS Award of Garden Merit and is an excellent choice for cut flowers as well as adding colour to borders and beds.
