Apricot Bubble Gum gladiolus (Gladiolus × hortulanus ‘Apricot Bubble Gum’)
Gladiolus × hortulanus ‘Apricot Bubble Gum’ is a tender cormous gladiolus reaching 100 to 120 cm. Green sword-shaped leaves accompany upright spikes of apricot, pink, and coral funnel-shaped flowers with paler markings. Bloom occurs from summer into early summer. Plant the ten Van Noort corms in early spring, 10–15 cm deep and 10 to 15 cm apart, in full sun and freely drained soil. The RHS rates it protection hors gel, without an automatic equivalent Canadian zone. Use it in borders, gravel gardens, wildflower meadows, and cut-flower plantings. Allow foliage to yellow naturally after bloom. In colder climates, test a protected site or use containers rather than assuming winter survival.

Reproducible seedsYes
Apricot Bubble Gum gladiolus produces long summer spikes filled with large ruffled flowers in apricot, pink, and coral shades. Florets open gradually from the bottom upward, extending the colour display and making it easy to cut stems at the right stage. Narrow, upright, sword-shaped leaves form a green clump at the base. This horticultural cultivar in the genus Gladiolus, family Iridaceae, reaches 100 to 120 cm tall. The eight Van Noort corms create a warm vertical group in sunny borders, cutting gardens, and large containers while supplying luminous stems for bouquets. Closely blended shades remain cheerful without losing their refined, softly layered character.
Plant corms in spring after the last frost once the soil has warmed. Choose full sun, shelter from strong winds, and fertile, loose, freely drained soil. Set each corm pointed end upward about 10 cm deep and space them 10 to 15 cm apart. Water after planting, then maintain even moisture during growth without waterlogging the ground. Staggered plantings every two weeks extend the harvest of flower spikes. Stake discreetly in exposed locations. In containers, use a heavy, deep pot with several open drainage holes to support tall stems during summer rain and wind. Avoid high-nitrogen fertilizer, which promotes leaves instead of sturdy flower spikes.
Flowering generally extends from July through September. Cut spikes when the two lowest florets begin to show colour, leaving several leaves on the plant to feed the corm. After flowering, allow foliage to yellow, then lift corms before hard frost. Dry and clean them before storing in a cool, dry, dark, frost-free place until spring. Combine Apricot Bubble Gum with burgundy dahlias, cream cosmos, purple sages, peach zinnias, and delicate ornamental grasses. All parts are ornamental and must not be eaten; keep stored corms away from children and pets. Inspect them during storage and discard any that become soft, mouldy, or badly damaged.

Propagation
Corms and separation of cormlets during dormancy
Growing method
Plant the corms in early spring in a warm, sheltered position with full sun. Loosen soil to at least 20 cm and incorporate fine gravel where drainage is slow. Set each corm 10–15 cm deep with the point upward and about 10 cm between plants. Arrange all ten in irregular clusters or two staggered rows so the slender stems support one another visually. Water after planting when soil is dry, then maintain moderate moisture during rooting and active growth without saturating the ground. Mature compost is sufficient; avoid high-nitrogen feeding that encourages weak stems. Add discreet support only in windy positions. Remove faded spikes above the leaves but allow all foliage to yellow. In a compatible protection hors gel site, leave corms in drained ground; elsewhere, test a small group or keep part of the batch in protected containers. Check emerging shoots after heavy rain and gently loosen any crusted surface soil. Label the group because foliage disappears during dormancy. Permanent placement reduces damage to cormlets and encourages more regular flowering over time. Keep vigorous roots and dense groundcovers away from the planting pocket so the corms receive sun, airflow, and adequate moisture without competition.

Watering
After planting, water to settle the soil, then wait for shoots before increasing irrigation. During active growth and flowering, provide approximately 2.5 cm (1 in) of water weekly when rain is absent. Water at soil level in the morning and let the surface drain. Reduce moisture gradually after bloom so corms mature before dormancy. Consistent moisture supports even spikes. Containers may need more frequent checks during hot, windy weather.
Soil type
Choose light, freely drained soil in full sun. Loam, sand, or chalk at any pH is suitable when excess water drains quickly. Avoid cold saturated clay, especially during dormancy. In a borderline climate, the base of a south- or west-facing wall creates a warmer sheltered microclimate and reduces winter moisture around the corms. Add fine gravel where necessary to improve soil structure and protect dormant corms from prolonged winter wetness.
Fertilization
Incorporate mature compost before planting. When shoots reach 10 to 15 cm (4 to 6 in), apply balanced slow-release fertilizer or a half-strength liquid feed. Repeat once as buds begin forming. Avoid excess nitrogen, which promotes foliage and weak stems at the expense of flowers and the corm’s stored energy. Stop feeding after bloom so foliage can mature naturally and corms can enter dormancy with firm, well-ripened tissues.
Moisture
Maintain moderate, even moisture through establishment, active growth, and flowering without leaving corms in saturated soil. Rapid drainage is essential for winter hardiness, especially in a borderline protection hors gel site. Reduce irrigation as foliage yellows. Light mulch conserves summer moisture, but keep it away from emerging shoots to preserve airflow and prevent crown rot after prolonged rain or repeated winter thaws in Quebec gardens.
Seasonal care
In early spring, inspect corms and discard those that are soft, badly shrivelled, or spotted. Prepare a full-sun site where water drains quickly, then plant 10–15 cm deep and 10 to 15 cm apart. Mark the group so shoots are not disturbed. During growth, weed by hand, water when the surface dries, and keep mulch light. Mature compost or a low dose of balanced fertilizer at emergence is sufficient. Watch for thrips, aphids, and slugs; remove badly affected tissue and avoid wetting foliage in the evening. Support only stems exposed to wind. For bouquets, cut a spike as the first flowers open while retaining as many leaves as possible. After bloom, remove faded spikes, reduce water gradually, and allow foliage to yellow completely. In a compatible protection hors gel site, clear dead leaves and leave corms in drained ground. In colder climates, divide the batch: test several corms under dry protection and store containers frost-free. Separate cormlets during dormancy if the colony becomes crowded, clean tools, and never replant diseased corms. During winter, avoid piling wet material over the planting area. Check stored containers monthly and remove any soft corm immediately. In spring, return containers gradually to brighter light and resume watering only when growth begins. Refresh drainage channels after snowmelt, mark surviving outdoor clumps, and compare their performance with the protected group before deciding how much of the next batch to leave in the ground.

Recommended pot size
35 to 100 to 120 cm (14 to 16 in) wide and at least 10 cm (12 in) deep for 8 corms
For eight corms, choose a heavy container at least 40 cm wide and 35 cm deep with several drainage holes. Blend quality potting mix with mature compost and about one-quarter pumice, coarse perlite, or fine gravel. Set corms 10–12 cm deep and 8–10 to 15 cm apart, then water if the mix is dry. Place the pot in full sun sheltered from prevailing wind, and insert a support ring before stems lengthen when needed. During growth, water when the upper 3 cm dries and feed lightly at emergence and again as buds form. Retain every leaf after flowering. As foliage yellows, reduce and then stop watering. In a compatible protection hors gel climate, protect the pot from excessive rain and freeze-thaw cycles. In colder regions, move the container into a cool, dark, frost-free space. The following spring, replace part of the mix, separate cormlets, and replant only firm healthy corms. Check drainage holes after every heavy rain and empty the saucer promptly. Label the pot with the botanical name and planting date. A thin gravel surface layer stabilizes the stems without retaining excessive moisture around shoots. Keep the container away from roof runoff and rotate it weekly so all spikes receive balanced light. Inspect corms before replanting and discard any showing softness, mould, or sunken lesions.

Bloom period
From summer into early summer, upright spikes carry numerous apricot, pink, and coral funnel-shaped flowers. Each bloom is about 5 cm wide and shows paler markings on the tepals. Green sword-shaped leaves rise almost as high as the stems and strengthen the vertical silhouette. Cut several spikes as the first buds open, or leave them to animate a sunny border, gravel garden, or naturalistic meadow planting.
Garden associations
Companion plants & uses
Companion plants
Choose dahlias, compact cannas, salvias, verbenas, cosmos, zinnias, and fine grasses that share a preference for sun, warmth, and draining soil. Purple or bronze foliage echoes the dark flower throat, while blue blooms provide a cool contrast. Avoid bog plants and dense groundcovers that trap moisture around corms or complicate cormlet division. Yarrows and bearded irises extend the early-summer display around the spikes. Leave open soil around each cluster so lifting tools can enter without damaging neighbouring crowns, and maintain clear airflow during humid weather.
Garden use
Plant all 8 corms as a group in a sunny border, warm-toned garden, colour garden, or large container. Their vertical outline fits between broader perennials and extends bloom into late summer. Spikes are excellent for bouquets and continue opening buds in a vase. Position another group near a patio to enjoy the evening colour while keeping the toxic plant beyond the reach of pets. In colder regions, start corms in pots to ensure flowering before frost. Their colour is most rewarding where people pass during late afternoon and evening.
Frequently asked questions
Frequently asked questions
When should Apricot Bubble Gum corms be planted in Quebec?
Set each corm 8 to 10 cm (3 to 4 in) deep, with the small point or bud facing upward and the flatter base downward. Leave approximately 10 to 15 cm (4 to 6 in) between units and cluster all 10 for a visible effect. If orientation is difficult to recognize, place the corm on its side; the shoot will turn upward naturally. Wait until soil is warm and frost danger has passed. In heavy ground, add fine gravel or plant on a slight mound. Water after planting, then only moderately until leaves appear to reduce the risk of rot. Mark the group clearly after planting because emergence may be later than nearby annuals.
How deeply and how far apart should they be planted?
The RHS rates this gladiolus protection hors gel and describes it as a tender type that can remain in the ground in a sunny, freely drained position. That rating belongs to the British system and does not convert directly to a Canadian zone. In many cold Quebec regions, winter survival therefore remains uncertain, especially in heavy or wet soil. To reduce risk, plant deeply beside a warm wall, apply dry winter protection, or grow several corms in containers that can be stored frost-free. You may also leave a small group outdoors as a local trial. Lift the corms if you want to preserve the entire batch without accepting this climatic uncertainty.
How can summer flowering be extended?
After flowering, remove faded spikes but let leaves yellow so reserves return to the corm. In a sunny, freely drained site compatible with protection hors gel, clear dead foliage and leave corms in the ground. In a colder climate or wet soil, lift them after yellowing, dry them briefly, and store them in a paper bag or ventilated box in a cool frost-free place. Inspect them during winter and remove any soft or mouldy piece. Separate cormlets without injuring their base and label the batch clearly before spring replanting. Never seal damp corms in plastic or expose them to heated household air.
Is Apricot Bubble Gum suitable for bouquets?
Provide at least six hours of sun, fertile soil without excess nitrogen, and consistent moisture while stems elongate. In a windy site, install a support ring early, before spikes bend. Harvest when the first bud shows colour or begins opening. Work in the morning with a clean tool and leave several leaves on the plant so the corm retains vigour. Recut the base under water, remove only leaves that would be submerged, and place the stem in a clean vase. Change water every two days; upper buds generally continue opening and releasing colour. Keep the arrangement away from direct heat and ripening fruit.
How should the corms be overwintered in Quebec?
Every part of Gladiolus × hortulanus ‘Apricot Bubble Gum’ is grown as an ornamental and must not be eaten. The RHS also warns of harm to pets if ingested. Corms present particular concern, but leaves and flowers are not intended for consumption. Keep packages, stored corms, and planting debris beyond the reach of children and animals. Wear gloves if handling irritates your skin. If ingestion is suspected and drooling, vomiting, diarrhea, weakness, or abdominal pain develops, promptly contact a veterinarian or poison centre and provide the name Gladiolus × hortulanus ‘Apricot Bubble Gum’. Do not induce vomiting or offer treatment unless a qualified professional gives specific instructions.

Supporting wildlife
Star-shaped flowers may attract daytime butterflies and some long-tongued pollinators, while evening colour signals blooms to insects active near dusk. This contribution is complementary within a diverse garden. Avoid insecticides, retain several uncut spikes, and grow nearby nectar plants with more accessible flowers to support a broader range of visitors.
