Is a cast iron plant right for you?

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 cast iron plant can reach 2-3 ft and growth is slow, so a smaller plant will take time to fill out; buy closer to the size you want.
What to check when buying: a healthy cast iron plant
- Firm, evenly colored leaves with no mushy stems at the soil line.
- Soil that is not sour-smelling or waterlogged when it arrives.
- No webbing, sticky residue or tiny moving insects under the leaves.
- Roots, if you peek, that are pale and firm rather than brown and soft.
Problems to know about before buying:
- Brown patches: Sunburn.
- Yellow leaves: Overwatering.
- Slow growth: Normal for this plant.
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We do not quote prices until we have checked them.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 low 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: Cast Iron Plant care.
