About Baboon Flower

Babiana stricta · also called Baboon flower, Blue freesia · flowering

Babiana stricta is a cormous perennial from the Cape region of South Africa, producing fragrant, vividly coloured funnel-shaped flowers in violet, purple, blue, pink, or yellow on pleated, lance-shaped foliage in spring. In the UK and colder climates it is grown as a conservatory or cool greenhouse plant, with corms planted in autumn and allowed to dry off after flowering. The most important care rule is to provide a frost-free but cool winter rest with dry corms — it tolerates only very light frost at best. No confirmed ASPCA toxicity listing exists; treat with caution around pets.

Growth habit: Upright, cormous perennial with pleated, lance-shaped foliage and clustered flower spikes.

What fertiliser baboon flower actually wants — and why

Baboon Flower is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.

A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for baboon flower: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed baboon flower, and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For baboon flower:

Apply a weak, balanced liquid fertiliser every three weeks from shoot emergence until the flower buds show colour; do not feed during dormancy. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.

The dormant-season rule matters more than the exact interval: skip feeding entirely when baboon flower is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for baboon flower

Half strength is the safe default for baboon flower — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

Feeding always goes onto already-damp soil, never dry roots — water baboon flower first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the baboon flower watering schedule.

Signs you are over-feeding baboon flower

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for baboon flower:

Flushing and leaching the salts

Flush the pot of baboon flower with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.

Organic vs synthetic feeds for baboon flower

Organic options

A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.

Synthetic / liquid feeds

A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What strength of feed for baboon flower?

Half strength is the safe default for baboon flower — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

What does over-feeding baboon flower look like?

Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding baboon flower year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.

Should I flush the soil of baboon flower?

Flush the pot of baboon flower with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
