A fungal attack causes an outbreak of spots on the leaves. The dark marks are often surrounded by a pinkish-purple ring.
This fungal problem results in rounded spots on the leaves. Although it's unsightly, leaf spot is only a significant problem on poorly growing or unhealthy plants, which might end up dropping a substantial number of leaves.
Promptly remove and destroy all infected leaves, both on the plant and on the ground. Don't put them on the compost heap. Also improve the growing conditions - add a mulch of well-rotted compost, and regularly feed and water. Keep deadheading.

within 2 days the leaves of my 2 very large plants have turned black,shrivelled and drooped. They have been healthy for the past 12-15 years. The leaves are that shrivelled they look dead. Any ideas what this may be.
