Macwairar – yellow hybrid tea rose – MACwairar
The Macwairar hybrid tea offers a reliably upright, bush-trained framework with 3–5 strong canes, well suited to premium container production from pharmaROSA® NEONATAL own-root material. Its high-centred, cut-rose form and large, solitary flowers support an exclusive finished-product positioning aimed at retailers and resellers focused on flower quality. The vivid lemon-yellow colour holds well from bud to full bloom, with very good retention and a refined fading pattern that underpins visually consistent batches on the bench. Own-root production provides a long-term, renewable base for nursery and wholesale programmes, giving predictable structural performance and stable stands in thematic or collection plantings, including public-realm rose gardens in cooler UK regions where winter-tolerant material is essential for dependable cycles. With appropriate protection for its disease sensitivity, growers can leverage the remontant, plentiful second flowering to programme repeat flushes, aligning Year 1 roots, Year 2 shoots and Year 3 full ornamental value for a durable, high-spec cut-flower and display-line offer.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Hybrid tea rose cultivar with registered name MACwairar, marketed as Macwairar yellow hybrid tea rose, approved American Rose Society exhibition name Aperitif; classified commercially as a hybrid tea rose type. |
| Origin and breeding |
Bred by Samuel Darragh McGredy IV in New Zealand in 1988 from ‘Solitaire’ × ‘Sunbright’; introduced by McGredy Roses International (NZ) in 1998 and Jackson & Perkins (USA) in 2001, registered in 1988. |
| Growth and structural characteristics |
Upright habit with moderately dense, matt light-green foliage and moderate prickliness; height 130–170 cm with 75–105 cm spread, well suited to bush training on 3–5 strong canes for container or bed production. |
| Flower morphology |
Large, solitary blooms with semi-double, high-centred, pointed flowers typical of cut-rose forms; 13–25 petals, remontant habit producing a plentiful second flush under suitable culture. |
| Colour data and phenology |
Pure, vivid lemon-yellow flowers (ARS MY; RHS 11B outer, 12A inner) with very good sunlight fastness, fading gradually from deep lemon to mid-yellow then pastel yellow while maintaining uniform mid-yellow tone at full bloom. |
| Fragrance and aroma |
Mild, restrained scent with a gently spicy character; fragrance present but not dominant, allowing the cultivar to focus on visual impact and stem quality in cut and display uses. |
| Hip characteristics |
Occasional spherical hips, 8–12 mm diameter, red at maturity; generally incidental to production but of note for seed or display in low-intervention plantings where hips may develop. |
| Resistance and winter hardiness |
Hardy to approximately −26 to −23 °C (RHS H7, USDA 5b, Swedish zone 4), with moderate heat tolerance requiring irrigation during drought; disease sensitivity necessitates regular protection, especially against rust and foliar diseases. |
| Horticultural recommendations |
Best used for cut flowers and high-end container production; maintenance requirement high with frequent plant protection; recommended as bush-trained release in 5–7 L premium containers, integrating structured spray and monitoring programmes. |
