These daisies come in all sorts of colours, these in particular, started off as a cream in colour and now have clearly changed to a mauve or pink in colour.
I would suggest that if you buy a yellow osteopermum daisy, they would look lovely against a white rose, as they would enhance the colour of the rose and bring I to the for.
The other colours include a deep orange that also looks nice against th yellow, and they do spread to enhance the borders and patio areas
You don’t have to replace these daisies either, as thy do come back every year, they are a joy to plat in and watch grow throughout the season, they seem to flourish in extreme heat and extreme cold.
I would strongly recommend these as they also need little watering and draught conditions.
