Dieffenbachia (dumb cane) has large leaves splashed with cream and green and grows fast in ordinary rooms. Its sap is irritating, so it is not a choice for homes with pets or toddlers who chew plants.

Is a dieffenbachia right for you?

Similar plants to consider: Monstera, Pothos, Snake Plant, ZZ Plant.
Size and age buying guide
| Size | What you usually get | Why choose it |
|---|---|---|
| Tabletop / shelf | Usually a 4-6 in nursery pot. | Cheapest way in; expect a long wait to reach a large size. |
| Medium | Usually a 6-8 in pot, for a desk or plant stand. | A fuller plant now, still easy to ship and place. |
| Large / floor | Usually a 10 in or bigger pot; check the listed height. | Instant impact; costs more and ships in a large box, so check delivery terms. |
Younger or older plant? A younger, smaller plant costs less and settles in easily; an older, larger plant gives you the look straight away but costs more to buy and ship. With a moderate growth rate and a mature size of 2-5 ft, buy close to the size you want.
Sizes and what you will receive
Online shops sell plants by nursery pot diameter: about 4 in (small, shelf), 6 in (desk or table), 8-10 in (small floor plant) and 12 in and up (floor statement). Height varies a lot within one pot size, so read the listed height too. A mature dieffenbachia can reach 2-5 ft and growth is moderate, so a smaller plant will take time to fill out; buy closer to the size you want.

Prices
We do not quote prices until we have checked them. They change with pot size, season and sales. To compare fairly, compare the same pot size and check whether a decorative pot and shipping are included.
Shipping and seasonal risks
Tropical plants like this one suffer below about 50°F (10°C). In winter, order from a shop that adds heat packs or holds shipments in freezing weather, and bring the box inside as soon as it arrives. Summer heat in a delivery truck can also damage plants, so avoid long weekends in transit.
Your first week after delivery
- Unbox right away and photograph any damage; most guarantees need photos within a set window.
- Water only if the soil is dry; many plants arrive already moist.
- Give it medium to bright indirect light, but avoid harsh direct sun for a few days.
- Keep it away from other plants for one to two weeks in case of pests.
- Wait two to four weeks before repotting. Full care guide: Dieffenbachia care.
