Red Lilies: Varieties and Growing Guide

Red lilies overview

Red lilies include hundreds of named varieties across several lily divisions. Asiatic hybrids offer the widest selection of true reds, blooming in June in Zones 3–9. Oriental-Trumpet hybrids extend the red season into late summer with added fragrance. All red lilies need full sun, well-drained soil, and foliage left standing until it yellows after bloom.

Red is one of the most sought-after colors in summer bulb gardens, and true lilies (Lilium species) deliver it reliably across most of the US. The challenge is that “red lily” covers a wide range of flower forms, heights, bloom times, and cultural requirements depending on which division the variety belongs to. Choosing the right type for your zone and timing gets you bold red color precisely when you need it.

Types of red lilies by division

The American Lily Society organizes lilies into 9 divisions based on parentage and flower form. Most red-flowering lilies fall into four divisions:

Division 1 — Asiatic hybrids

Asiatic hybrids are the easiest red lilies to grow and the most widely available in US garden centers.

Bloom time: June to early July
Height: 2–4 feet
Fragrance: None to very slight
USDA Zones: 3–9
Flower form: Upward-facing, outward-facing, or slightly pendant; clean, bold colors without the complex markings of Orientals

Asiatics are bred for color intensity and cold hardiness. Red Asiatics range from bright cherry-red to deep burgundy to tomato orange-red. They multiply by bulb offsets and establish quickly in their first season.

Reliable red Asiatic varieties:

• ‘Brunello’ — deep orange-red; upward-facing; widely available; reliable Zone 3–9
• ‘Red Matrix’ — pure, vivid red with slightly recurved petals; mid-June bloom
• ‘Royal Sunset’ — rich crimson-red; vigorous and multiplies readily
• ‘Lollipop’ — white with bold red center blotch; bi-color; Zone 3–9
• ‘Grand Cru’ — golden yellow with red center; not a pure red but striking and very popular

Division 6 — Trumpet and Aurelian hybrids

Trumpet lilies include some red and deep burgundy cultivars, though true-red Trumpets are less common than in Asiatics.

Bloom time: Midsummer, July
Height: 4–6 feet, sometimes taller
Fragrance: Strong, sweet
USDA Zones: 4–9

The fragrance of Trumpets is the strongest of any lily division. For gardeners who want both red color and fragrance, Trumpets are the option — though the selection of deep reds is smaller than in Asiatics.

Division 7 — Oriental hybrids

Oriental hybrids produce large, outward-facing or reflexed flowers in July and August, often heavily fragrant. Many Orientals have pink, burgundy, or red-streaked forms rather than solid red.

Bloom time: Late summer, July–August
Height: 3–5 feet
Fragrance: Very strong
USDA Zones: 4–8

‘Stargazer’ is the best-known Oriental with red coloring — technically crimson-pink with white margins, but striking in the garden. For deeper red in the Oriental class, look for ‘Tom Pouce’ (rose-red) and ‘Acapulco’ (deep magenta-pink).

Division 8 — OT hybrids (Orienpet)

Orienpet hybrids (Oriental × Trumpet crosses) combine the large flowers and fragrance of Orientals with the tall, vigorous habit of Trumpets. They bloom after Asiatics, extending the lily season into late summer.

Bloom time: Late July through August
Height: 5–8 feet
Fragrance: Moderate to strong
USDA Zones: 4–9

OT reds are some of the most visually dramatic plants available for US summer gardens. ‘Satisfaction’ (deep rose-red), ‘Red Alert,’ and ‘Shocking’ are popular OT varieties with strong red coloring.

Planting red lily bulbs

When to plant

Fall planting (preferred): Plant in October–November after temperatures cool below 50°F at night. Fall-planted bulbs establish roots before the ground freezes and produce more flowers in their first season than spring-planted bulbs.

Spring planting: Plant as soon as the ground can be worked in March–April. Spring-planted bulbs bloom reliably the same season but may produce slightly fewer flowers in year one.

Planting depth and spacing

Plant lily bulbs with the pointed tip facing up, at a depth of 2–3 times the bulb diameter:

Most garden-center red lily bulbs are medium to large, so 4–6 inches deep is standard. If you’re unsure which end is up, plant the bulb on its side — stems find their way up naturally.

Drainage is the single most critical factor. Lily bulbs rot in standing water. In clay-heavy soil, amend the bed with coarse grit or perlite before planting, or build a raised bed.

Sun and soil for red lilies

Sun: Red lilies need 6–8 hours of direct sun per day. In Zones 8–9, afternoon shade after 3 p.m. can help extend bloom and prevent color fading on hot days, but morning sun is essential.

Soil: Loamy, well-drained soil with a pH of 6.0–6.5. Amend with compost before planting to improve drainage in clay or moisture retention in sandy soil.

Soil preparation:

1. Loosen soil 12 inches deep in the planting area
2. Work in 2–3 inches of compost
3. In heavy clay: add coarse grit or perlite at a ratio of 1 part grit to 4 parts soil
4. Do not add fresh manure — it promotes fungal rot in lily bulbs

For pairing red lilies with other warm-season performers, see full sun perennials for companion and timing ideas.

Watering and fertilizing

Watering schedule:

• At planting: water thoroughly to settle soil around bulbs
• Spring through bloom: water when the top inch of soil dries; aim for consistent moisture, not saturation
• After bloom: reduce watering gradually as foliage begins to yellow
• Avoid overhead watering — wet foliage in humid conditions promotes Botrytis (gray mold)

Fertilizing:

• Apply a balanced granular fertilizer (10-10-10) when shoots emerge in spring
• Switch to a low-nitrogen formula (5-10-10) as buds form — this supports flower development without pushing excess leaf growth
• Stop fertilizing when foliage begins to yellow; the bulb is going dormant

After red lilies bloom

What you do after flowering directly determines whether your red lilies return as well the following year.

Deadhead spent flowers: Once red petals drop, remove the spent flower head and any forming seed pod. Seed production pulls energy from the bulb. Cut or snap off at the base of the flower, leaving the full stem intact.

Do not cut the stem: The green stem and all leaves must remain standing until they turn yellow and come free with no resistance — typically 6–10 weeks after bloom. Every week the foliage stands, it’s manufacturing food for the bulb to store for next season.

Cutting early is the most common red lily mistake. Gardeners often pull the stem as soon as flowers drop because spent red lily stems can look unattractive. But a stem cut while still green starves the bulb. Plants treated this way bloom poorly or not at all the following year.

Mark each stem with a stake or bamboo cane after deadheading so you remember what’s there as the foliage yellows and becomes less visible.

Red lily beetles: the main pest

The red lily beetle (Lilioceris lilii) is the most damaging pest to all true lilies in the eastern US, including red-flowered varieties. Adults are bright red, about ½ inch long, and appear in early spring when lily shoots emerge.

Identifying red lily beetles:

• Vivid scarlet or red-orange on the back, black undersides and legs
• Drop to the ground when disturbed, landing black-side-up to camouflage
• Larvae cover themselves in dark brown excrement for camouflage — unsightly but identifiable

Damage: Red lily beetles eat leaves, stems, and flower buds. A moderate infestation can defoliate a plant within 1–2 weeks, preventing it from storing energy for the following year.

Control:

1. Hand-picking (most effective for small gardens): Inspect plants weekly from early spring. Pick adults off and drop them in soapy water. Hold a container under the plant when picking — they drop fast when touched.
2. Check undersides of leaves: Larvae feed primarily on the undersides of leaves. Remove larvae by hand or wash off with a hose.
3. Spinosad spray: For heavy infestations, spinosad is an organic option effective on larvae. Apply in the morning when bees are less active.
4. Neem oil: Provides some control but degrades within 3–5 days; requires frequent reapplication.

Red lily beetles are established in the Northeast, spreading westward. Check your state’s cooperative extension to determine if they are present in your area.

Extending red lily color through the season

Plant a combination of divisions to stretch the red color window from early June through August:

In a Zone 5–7 garden, this combination gives approximately 8–10 weeks of red lily color from a single planting effort. The Asiatics and OTs don’t compete — each finishes before the next one opens.

Red lilies by US region

Northern gardens (Zones 3–4): Asiatic reds are the practical choice. They are reliably cold-hardy without supplemental protection. OT hybrids can succeed with 3–4 inches of mulch applied in November.

Mid-Atlantic, Southeast, Midwest (Zones 5–7): Full selection is available. Asiatics for June, Orientals for July fragrance, and OTs for late summer. This is the easiest region to grow all red lily types.

Gulf Coast and Southeast (Zones 8–9): Asiatics tolerate Zone 9 in well-drained soil with afternoon shade. Oriental reds struggle in high heat — use OT hybrids instead, which tolerate heat better than pure Orientals.

Dividing red lily clumps

Red lily clumps become crowded after 3–5 years, producing more stems but smaller flowers. Divide when stems are noticeably thinner than in previous years.

When: Fall, after foliage has completely yellowed and died back.

How:

1. Dig the clump carefully, going 8–10 inches deep to avoid cutting bulbs
2. Separate bulb offsets (small attached bulblets) from the parent bulb
3. Replant the main bulbs immediately at correct depth
4. Offsets take 1–3 years to reach blooming size

Dividing also gives you extra bulbs to move to new garden spots or share.

Common problems with red lilies

Flowers fading to orange or pink: Some red Asiatics, especially ‘Brunello,’ shift toward orange in very hot summers. This is genetic, not a disease. Choose varieties with stable red pigment if color accuracy matters — ‘Red Matrix’ holds color better in heat.

Few flowers after the first year: Almost always caused by cutting the green stem too early. Leave foliage until fully yellowed.

No flowers at all: Check sun exposure (6+ hours required), drainage, and whether bulbs may have been disturbed by digging or vole activity.

Yellowing leaves before bloom: Can indicate overwatering, root rot from poor drainage, or Fusarium (basal rot). Dig a suspicious bulb — healthy tissue is white and firm; rotted tissue is brown and soft. Remove affected parts, treat cut surfaces with fungicide dust, and replant in improved drainage.

According to the American Lily Society, Asiatic hybrids represent the largest category of named lily cultivars worldwide, and red is among the most frequently developed color groups — meaning gardeners have extensive selection among red varieties at every price point and size.
