Wood sorrels can be annuals or perennials that have anywhere from three to ten leaflets. Due to their similar appearance, these plants are often mistakenly referred to as clover. Several cultivars are grown as container plants, while others are used in ornamental gardens. Foliage color ranges from light green to dark purple.
Species of Wood sorrels
Volcanic sorrel derives its common name from the area where it was first officially collected — near the Irazu Volcano in Costa Rica. While it grows naturally in montane forests, it is also a favorite of gardeners, especially as a filler for container planting. Its stems are semi-succulent so it can withstand semi-dry conditions better than other plants.
Flower language is "I will never throw you away" "Glittering heart".
Wood sorrels 'Cottage Pink'
Aptly named, wood sorrels 'Cottage Pink' has bright pink flowers that are attractive to pollinators, as well as lime green leaves. This cultivar has sterile seeds, meaning it does not pose a threat of becoming invasive. As such, it is used in both gardens and containers.
Wood sorrels 'Rosea'

Wood sorrels 'Molten Lava'
Wood sorrels 'Molten Lava' is a shamrock or oxalis variant, which has a range of appealing autumnal hues to its leaves. It is a perennial typically grown as an annual, and it blooms from late spring to mid-summer, providing delightful color and fine, dense texture to the garden.

Barrelier's woodsorrel (Oxalis barrelieri) is a hermaphrodite, part male, and part female. And so with the help of butterflies and other insects it attracts, it can self-propagate.

When the pale pink-sorrel flowers are open, the petals flare outwards, unlike the wood sorrel. It is native to South Africa and is grown as an ornamental plant worldwide. This plant's heart-shaped green leaves are edible; however, they should not be consumed in excessive numbers due to their high oxalic acid concentration.
The specific epithet in the scientific name of mountain wood-sorrel (Oxalis montana) is “montana,” which means “mountain.” That’s because it’s a shade-loving species that thrives best at higher elevations.

This perennial forms full mounds of heart-shaped leaves that grow in the shape of a cross. It blooms bright pink flowers through summer and fall, and is a good choice for containers and rock gardens.
