Puccinia thaliae is the causal agent of canna rust, a fungal disease of Canna. Symptoms include yellow to tan spots on the plant's leaves and stems. Initial disease symptoms will result in scattered sori (clustered sporangia), eventually covering the entirety of the leaf with coalescing postulates.
The berries and leaves of several species are mildly toxic to humans, dogs, cats, livestock, rabbits, and tortoises, containing terpenoid glycosides which can cause extreme irritation to the hands and mouth upon contact and digestive distress if ingested; children and small animals are particularly susceptible.

The solution: You can remove old, yellow peace lily leaves with scissors or by pinching them off the plant with your fingers. This improves the look of your peace lily and redirects the plant’s ...
Common names include arum lily for Z. aethiopica, calla and calla lily for Z. elliottiana and Z. rehmannii. However, members of this genus are not true lilies [ 4 ] (which belong to the family Liliaceae ), and the genera Arum and Calla , although related, are distinct from Zantedeschia , despite visual similarities.
It grows to 0.6–1 m (2.0–3.3 ft) tall, with large clumps of broad, arrow shaped dark green leaves up to 45 cm (18 in) long. The inflorescences are large and are produced in spring, summer and autumn, with a pure white spathe up to 25 cm (9.8 in) and a yellow spadix up to 90 mm (3 + 1 ⁄ 2 in) long. [3]
The flowers are borne on a stem that arises from a bulb, generally in the spring or early summer. Flowers can be white, yellow, pink, purple, bluish, or streaked. The insides of the petals are often very 'hairy'. These hairs, along with the nectaries, are often used in distinguishing species from each other. [5] Species [2] [10] [11] [12] [13]
Zantedeschia albomaculata, commonly called the spotted calla lily [2] (although Calla is a genus unto itself) or the white spotted arum, is a species of flowering plant in the arum family, Araceae. [3]
They are also susceptible to certain plant viruses, some of which are Canna-specific, which may result in spotted or streaked leaves, in a mild form, but can finally result in stunted growth and twisted and distorted blooms and foliage. [22] The flowers are sometimes affected by a grey, fuzzy mold called botrytis. Under humid conditions, it is ...
