Just bought this for the first time, in a hanging basket. I have other African daisies in the ground. I liked it's bloom time thru fall and it can take our heat.

It's a little hardier than zone 10a, but ours has overcome -3C, looks a little scruffy, but now it's fairly mild, is throwing up more flowers. This one will surely flower all year round if given the chance. If it survives the winter it will be interesting.. despite frost not being too prevalent here, the moist ground is usually a problem, however this Osteospermum has dealt admirably with that, with only minor frost damage. The neutral is for the fact the leaves can look scruffy in winter if frost occurs.

Finally died at -4C (25F) last year (hardiness between -2C and -3C, 29F and 28F)
