About Florist's Gloxinia

Sinningia speciosa · also called Florist's gloxinia, Brazilian gloxinia · flowering

Florist's gloxinia (Sinningia speciosa) is a tuberous Brazilian gesneriad grown for velvety leaves and large, bell-shaped flowers in jewel tones. Give bright indirect light, evenly moist soil, warmth and high humidity, then a dry winter rest. The ASPCA lists it as non-toxic to cats, dogs and horses.

Mature size: Compact: roughly 6-12 inches (15-30 cm) tall and wide, with flowers often 3+ inches (8 cm) across.

Watch for — Brown spots on leaves: Caused by water sitting on the velvety foliage, especially cold water. The marks are permanent. Always water from below or directly onto the soil and keep droplets off the leaves and crown.

How to tell florist's gloxinia needs repotting

Repotting on a calendar is less reliable than reading the plant. For florist's gloxinia, watch for these signs:

Flowering has tailed off year on year and the clump has become congested and overcrowded.
Lots of leaf and few flowers — a classic sign that florist's gloxinia bulbs or tubers need lifting and dividing.
Bulbs visibly bursting the pot or pushing each other to the surface.
It is the natural dormancy window (foliage yellowed and died back) — the only safe time to lift and split.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot florist's gloxinia

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, florist's gloxinia is lifted and divided once the clump congests and flowering drops off. Low, mounding tuberous perennial with a rosette of large, soft, velvety leaves and upright, trumpet- to bell-shaped flowers held just above the foliage. Naturally dies back to its tuber for a dormant rest after flowering..

What size pot to step florist's gloxinia up to

Pot size matters less than depth and spacing here. When you replant florist's gloxinia, set the bulbs or tubers at the correct depth (a rough guide: two to three times their own height of soil over the top) and space them so they are not touching. A wide, shallow pot suits a clump better than a tall narrow one.

The best time of year to repot florist's gloxinia

The only safe window is dormancy: wait until the foliage has yellowed and died back naturally, lift and divide then, and replant before or at the start of the next growing season. Disturbing florist's gloxinia in full growth or flower sets it back badly.

Step-by-step: repotting florist's gloxinia

Wait for dormancy. Let florist's gloxinia foliage yellow and die back completely. Lifting while it is in growth wastes the energy it is storing for next year.
Lift carefully. Loosen the soil well away from the bulbs/tubers with a fork and ease the whole clump out without spearing them.
Separate the offsets. Gently pull the clump apart into individual bulbs or tubers. Keep only firm, healthy, blemish-free ones.
Replant at the right depth. Reset them in fresh light, well-draining, peat-based mix; an african violet mix works well. at the correct depth and spacing — not touching — so each has room to bulk up.
Water in and rest. Water once to settle them, then keep on the dry side until growth resumes. Do not feed until leaves are actively growing.

Aftercare

After replanting florist's gloxinia, keep the soil barely moist — not wet — until shoots appear; bulbs and tubers rot in cold, saturated soil. Once leaves are growing strongly, resume normal watering. Hold off feeding until the plant is in active growth again.

The right soil mix for florist's gloxinia

Florist's Gloxinia wants light, well-draining, peat-based mix; an african violet mix works well.. Use about 50% sifted peat (or coir) with perlite, coarse sand and a little vermiculite for aeration and drainage. It prefers slightly acidic conditions, roughly pH 5.5-6.5. The container must drain freely, as the tuber rots in waterlogged soil. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting florist's gloxinia — frequently asked questions

How often should you repot florist's gloxinia?

Lift and divide every 3–4 years once clumps congest for florist's gloxinia. Florist's Gloxinia is lifted and divided, not "repotted". Every 3–4 years, once the foliage has died back and it is dormant, lift the clump, separate the offsets, and replant at the correct depth in light, well-draining, peat-based mix; an african violet mix works well.. Crowding, not pot size, is what reduces flowering over time.

What size pot does florist's gloxinia need?

When is the best time of year to repot florist's gloxinia?

Do you "repot" florist's gloxinia, or lift and divide it?

You lift and divide it. Florist's Gloxinia grows from bulbs or tubers, so instead of repotting you wait for dormancy, lift the congested clump, separate the healthy offsets, and replant them at the right depth and spacing. Doing this every 3–4 years restores flowering.

Should you fertilise florist's gloxinia after repotting?

Hold off feeding florist's gloxinia until it is in active growth again. Fresh soil already carries enough nutrients to get it re-established, and feeding disturbed roots too soon does more harm than good.
