How to Care for Lilies: Safety & Longevity Tips

Lilies are among the longest-lasting cut flowers you can buy — a single stem can bloom for nearly two weeks, opening bud after bud in succession. They are also, in our 38 years at TJ Flowers, the flower we most frequently have to ask careful questions about before we deliver: Do you have cats?

Before anything else in this guide, the critical warning: lilies are highly toxic to cats. Not "mildly irritating" — actually, acutely, sometimes fatally toxic. If you live with a cat, please read the safety section below in full before bringing any lily into your home. For households without cats, lilies are one of the most rewarding flowers you can own, and we'll walk you through exactly how to get the most from them.

Critical: Lilies and Cat Safety

This section first, because it matters most. Every species of true lily (genus Lilium) and every species of daylily (genus Hemerocallis) is toxic to cats. This includes:

• Asiatic lilies
• Oriental lilies (including stargazers)
• Easter lilies
• Tiger lilies
• Daylilies
• Japanese Show lilies

What makes lilies toxic to cats

Every part of the plant is toxic — petals, leaves, pollen, stems, and even the water the lilies have been sitting in. A cat who chews a leaf, licks pollen off its fur after brushing against a bloom, or drinks from the vase can develop acute kidney failure within 24–72 hours.

Warning signs in a cat

• Vomiting
• Lethargy
• Loss of appetite
• Excessive drinking or urinating (then, ominously, reduced urination)
• Pollen staining on face or paws

If you suspect exposure, contact your vet or the ASPCA Animal Poison Control Center (888-426-4435) immediately. Treatment within 18 hours of exposure dramatically improves outcomes.

Safer choices for cat households

Roses, orchids, sunflowers, snapdragons, stock, and most garden varieties are safe around cats. Our rose arrangements and orchid selection are popular choices for pet-owning clients. For a deeper dive on keeping roses happy, see our rose care guide. If you're set on lilies but have cats, consider sending them as a gift to a cat-free household instead.

Unboxing Your Lilies: First Steps

Now to care. Lilies ship with most buds closed and one or two just starting to open — that's intentional. It means you'll get the full progression of blooms over 10–14 days at home.

First hour routine

1. Unwrap carefully — lily stamens shed pollen easily.
2. Fill a clean vase with cool water and flower food.
3. Recut each stem at a 45-degree angle, removing at least one inch.
4. Strip all leaves that would sit below the waterline.
5. Place stems in the vase.

The Pollen Question: Remove It Early

This step is important for two reasons: pollen stains fabric permanently (ask anyone who's brushed a stargazer against a white shirt), and removing pollen actually extends bloom life by three to four days.

How to remove lily pollen

1. Wait until each bloom has fully opened and the stamens (the pollen-bearing tips) are clearly visible.
2. Using a tissue or folded paper towel — not your fingers — gently pinch each anther (the orange pollen-covered tip) and pull it off.
3. Each bloom has six anthers. Remove all of them.
4. Discard the tissue (pollen stains are hard to wash out).

Why this matters for bloom life: once a lily is pollinated (which happens when pollen touches the stigma in the center), the flower begins to age rapidly. Removing the anthers before they shed halts this process and keeps the bloom crisp for days longer.

If pollen stains fabric

Do not rub or wipe — that presses pollen deeper into fibers. Instead, take the garment outside and brush off loose pollen with a dry toothbrush or use a piece of tape to lift it. Then leave in direct sunlight for several hours; UV breaks down the pigments. Only then wash with cold water.

Water, Light, and Temperature

Water

Lilies are moderate drinkers — less thirsty than hydrangeas, more so than orchids. Change water every 3–4 days, recutting stems half an inch each time. Use flower food throughout. Keep water clear; cloudy water means bacteria, and lilies are particularly vulnerable to stem-end rot.

Light and temperature

• Bright, indirect light extends bloom life. Direct sun burns petals.
• Keep at room temperature or slightly cool — 60–72°F is ideal.
• In NYC apartments, stay away from radiators (winter) and AC vents (summer). Pre-war buildings in particular run very warm; move the arrangement to a cooler room like a bedroom or hallway overnight.
• No proximity to ripening fruit — ethylene gas shortens lily life dramatically.

The Succession Bloom: Getting the Full 14 Days

A well-chosen lily stem will have 4–6 buds at various stages. Each bud opens in sequence, roughly 2–3 days apart. To maximize total bloom time:

1. As each lower bloom fades, snip it off cleanly at its base (leave the stem and upper buds intact).
2. This redirects the stem's resources to the remaining buds, making them larger and more fragrant.
3. Continue until the final top bud has bloomed and faded.

Done correctly, a single lily stem can provide 10–14 days of fresh blooms.

Fragrance Management

Oriental lilies and stargazers are intensely fragrant — beautiful in a foyer, overwhelming in a small bedroom. For NYC studios and one-bedrooms:

• Place lilies in a larger room or an area with airflow.
• If the scent is too strong, removing the anthers (step above) cuts fragrance roughly in half.
• Some people are sensitive to lily scent — keep this in mind before sending a bouquet to an office or hospital.

Frequently Asked Questions

How long do cut lilies last?

10–14 days with proper care — one of the longest-lasting cut flowers commonly sold. Each bloom itself lasts 5–7 days, and a multi-bud stem extends the total display.

Are lilies safe around dogs?

Mostly yes, but with caveats. True lilies (Lilium) and daylilies cause only mild stomach upset in dogs — not the acute kidney failure seen in cats. Lily of the valley (not a true lily despite the name) is seriously toxic to dogs and should be avoided. When in doubt, keep flowers out of reach of any pet.

Why are the tips of my lily petals turning brown?

Usually a humidity or airflow issue — common in heated NYC apartments. Move away from heat sources, mist lightly if the air is dry, and trim any browning tips with small scissors if appearance matters.

Can I put lilies in the fridge?

Yes, overnight storage at 34–40°F extends bloom life. Remove any fruit from the fridge first (ethylene), cover the arrangement loosely, and limit fridge time to 10–12 hours.

What's the difference between an Asiatic and an Oriental lily?

Asiatic lilies bloom earlier, have no fragrance, and come in vivid saturated colors. Oriental lilies (including stargazers) bloom later, have strong fragrance, and tend toward pink, white, and burgundy tones. Both last equally long as cut flowers.
