In most cases, many of the seed labelled as “Mustard and Cress” – the kind that grows on damp tissue is basically made up of two plant types – Cress (Lepidium sativum) and White Mustard (Brassica hirta), and this is fine to add as a small part of a tortoise’s varied diet.
In the UK, the small punnets of plants that are sold as “salad cress” in supermarkets are almost never Cress, but Oilseed Rape (Brassica napus) with tiny teeny bits of Cress included, and this is also fine as a small part of the diet.
Cress flowers are typically white, but can also be found in pink, and Oilseed Rape has yellow flowers.
