Mulberry
Morus spp.
Mulberries are fast, tough trees that bear blackberry-like fruit in spring, often in huge amounts. In Florida many cultivars fruit within a year or two of planting, and some bear in flushes for months. The fruit is too soft to ship, so a backyard tree is the main way to taste good ones.

Is mulberry safe to eat? Edible and toxic parts
What you can eat
- Ripe berries, raw or cooked
- Dried berries
- Leaves, dried for tea
Toxic parts and cautions
- Take care: Unripe berries and the milky sap in the leaves and stems can cause nausea, cramps and diarrhea, and the sap can irritate skin. Eat only fully ripe fruit.
- Good to know: Male white mulberry trees shed heavy, highly allergenic pollen. Fruiting cultivars sold for gardens are generally female or set fruit on their own.
- Good to know: Ripe berries stain skin, clothes, cars and patios, and birds spread purple droppings. Don't plant over a driveway or deck.
Pets: Ripe berries are fine for dogs in small amounts. Unripe berries, leaves and sap can cause vomiting and diarrhea.
How to eat and enjoy mulberry
- Fresh off the tree
- Pies, cobblers and crumbles
- Jam and syrup
- Dried mulberries, common in the Middle East and Central Asia
- Smoothies and sorbet
- Mulberry wine
When it's ripe
Ripe when fully colored (deep purple-black for black types) and soft enough to drop at a touch. Spread a sheet under the branch and shake: ripe fruit falls, unripe fruit stays.
Storing it
Very perishable. Refrigerate unwashed and use within 2–3 days, or freeze on a tray.
