Doris Tysterman – pharmaROSA® NEONATAL hybrid tea rose propagation material
Orange blooms, upright habit and dense foliage make Doris Tysterman a focused option where flower quality and form must underpin professional ranges, particularly for premium container production and exclusive finished product lines. As tray-grown, 3–6‑month‑old pharmaROSA® NEONATAL own‑root material, it supports predictable scheduling into 5–7 L premium containers and can be integrated into nursery propagation beds or container grids that supply retail and reseller partners at scale. Its high‑centred bud form and semi‑double structure provide exhibition‑style, solitary flowers suitable for cut‑flower and specimen roles in thematic rose gardens and curated collections. With medium self‑cleaning and medium disease resistance, the variety suits operators planning for moderate maintenance, aligning with UK nursery workflows where cold‑tolerant, reliably hardy roses must withstand winters similar to Scotland and North England, with good wind and frost tolerance over time. Own‑root structure offers long lifespan, regenerative capacity and low replacement in wholesale beds, naturally progressing from strong root establishment in year one, framework and shoot build‑up in year two, to full ornamental value and stable flowering expression in year three.

| Growth and structural characteristics |
Upright plants reach about 85–115 cm in height with a 70–95 cm spread, carrying dense, glossy bronze‑green foliage and moderate prickliness, forming a bush with 3–5 strong framework canes. |
| Flower morphology |
Semi‑double, medium‑sized flowers with approximately 13–25 petals are produced mainly solitary, with high‑centred, pointed buds; the variety is repeat‑flowering with an abundant second flush under suitable culture. |
| Colour data and phenology |
Colour is bright orange overall, with deep coppery‑orange buds, radiant orange opening with copper edging, then softer peachy orange tones that lighten in strong sun and remain richer in cooler weather. |
| Fragrance and aroma |
Fragrance is a mild, delicately sweet rose scent, noticeable but not overpowering, supporting use in close‑view plantings and cut‑flower situations where a subtle aromatic presence is preferred. |
| Hip characteristics |
Produces moderate numbers of ovoid hips, around 10–14 mm in diameter, coloured orange‑red, which may contribute modest seasonal interest and reflect successful pollination where flowers are left uncut. |
| Resistance and winter hardiness |
Hardy to approximately -26–-23 °C (RHS H7, Swedish zone 4, USDA 5b) with medium resistance to powdery mildew, black spot and rust, and moderate tolerance of heat and drought when adequately watered. |
| Horticultural recommendations |
Recommended for borders, specimen planting and cut‑flower use, with medium maintenance and occasional pest control; advised release form is bush‑trained premium containers of 5–7 L for exclusive finished product lines. |
