DIAMOND GRAY – light brown hybrid tea rose – Teranishi
Imagine a sheltered coastal veranda where sunlight glances off shingle and pale timber, and the unusual light brown blooms of DIAMOND GRAY echo driftwood and wet sand. This hybrid tea gives you generous, repeat flowering with a high‑centred, cut‑rose form, yet remains reassuringly manageable in an average family garden. Its own‑root habit supports a long‑lived, stable shape that copes well with blustery weather and helps the plant stay securely anchored even in exposed, breezy positions near the sea. In the first year it concentrates on roots, in the second on stronger shoots, and by the third it shows its full ornamental value with a calm, seaside ambience. With mid‑green, slightly glossy foliage, moderate fragrance and pollinator‑friendly, semi‑double flowers, it brings quiet elegance to small borders, gravel gardens and larger containers of at least 40–50 litres. Its good heat tolerance and reliable remontant habit give months of interest with minimal fuss, ideal if you want to enjoy the refreshment of tea outdoors rather than be tied to heavy pruning. Over time, this coastal-coloured rose becomes a characterful focal point, rewarding light, regular care with a uniquely mocha display that works beautifully with silvery grasses and sea‑inspired planting. Choose DIAMOND GRAY if you appreciate subtle tones, reliable structure and a relaxed, seaside‑garden feel without complicated gardening routines.

Bred by Teranishi Kikuo at Itami Rose Nursery, Japan; breeding year 2003, introduced 2004, with parentage not recorded, representing a distinctive mocha-toned hybrid tea from Japanese selection. |
| Growth and structural characteristics |
Spreading bush reaching 80–120 cm in height and width, with moderately dense, mid-green, slightly glossy foliage and moderate prickliness; weak self-cleaning so spent blooms benefit from occasional deadheading. |

Semi-double, high-centred, pointed buds in the classic hybrid tea style, produced in clusters on long stems; large flowers (approximately 7–10 cm), freely remontant with an abundant second flush in season. |
| Colour data and phenology |
Light mocha to pale beige-brown with a silvery-grey veil; buds sandy-brown, opening to taupe-brown then fading towards straw; good colour retention, though strong sun accelerates lightening of petal edges. |

Fragrance is mild and restrained, adding a gentle background scent rather than dominating seating areas; suitable where subtlety is preferred or where strong perfume could be overpowering in small spaces. |

Produces moderate quantities of ellipsoidal hips, approximately 12–18 mm in diameter, ripening to an orange-red colour and adding quiet late-season interest if spent flowers are not removed. |

| Horticultural recommendations |
Best in sunny positions with well-drained soil; plant 60–70 cm apart for hedging or groups, 110 cm as a specimen; medium maintenance, needing occasional pest control and deadheading to tidy weak self-cleaning. |
