Lupinus 'The Governor' (The Governor lupin) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Full sun is ideal in cool climates; in hot regions light afternoon shade prolongs the bloom. At least 6 hours of direct sun produces the strongest, most upright flower spikes. If your only bright window faces south, that's perfect for lupinus 'the governor' — same window any aroid would fry on.

Watering

Watering lupinus 'the governor': every 5-7 days; keep soil consistently moist, never waterlogged. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Lupins dislike both drought and soggy roots. Water deeply at the base in dry spells, especially during bud and bloom; mulch helps keep the root run cool and evenly moist.

Soil and pot

Lupinus 'The Governor' grows best in moist, well-drained, slightly acidic soil. Prefers neutral to acid loam or sand at pH 5.5-7.0; chalky, alkaline ground causes chlorosis. As a legume it fixes nitrogen, so avoid rich feeding. Sharp drainage prevents crown rot. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Lupinus 'The Governor' sits happiest at around Ambient outdoor humidity and -29 to 24°C (-20 to 75°F). A hardy border perennial indifferent to air humidity, though it performs best where summers are cool and not excessively muggy. Good airflow reduces mildew. If you keep the room above year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed lupinus 'the governor' sparingly. Feed sparingly. As a nitrogen-fixing legume it needs no nitrogen feed; a low-nitrogen, potassium-rich fertiliser in spring supports bloom. Excess nitrogen yields leafy growth and weak, floppy spikes. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on lupinus 'the governor' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Lupin aphid — Large grey aphids (Macrosiphum albifrons) infest spikes and weaken plants. Inspect early, dislodge with water or treat promptly; heavy infestations can collapse flower stems.
• Powdery mildew — Foliage greys and curls in dry, crowded conditions after flowering. Cut spent spikes, water at the base, and ensure good spacing for air movement.
• Crown rot in wet soil — Waterlogged or heavy clay rots the crown. Plant in free-draining ground, avoid winter wet, and never let the base sit in standing water.
• Chlorosis on alkaline soil — Yellowing between leaf veins signals lime-induced iron deficiency. Lupins need neutral-to-acid soil; amend chalky ground or grow in raised beds with ericaceous-leaning soil.

Propagation

Named Russell cultivars do not come true from seed, so propagate from basal cuttings taken in spring with a sliver of crown; root in gritty compost. Division is unreliable due to the deep taproot. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Lupinus 'The Governor' is toxic to pets. Toxic to cats and dogs. Lupinus contains quinolizidine alkaloids (lupinine, sparteine, anagyrine and others), most concentrated in the seeds and pods; the ASPCA and Pet Poison Helpline flag lupines/bluebonnets as toxic, causing salivation, GI upset, incoordination, tremors and, in large doses, breathing difficulty. Keep pets away from seedpods. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
