CASTA DIVA® – white hybrid tea rose - Barni
With CASTA DIVA® You bring a piece of opera-style elegance into your own Irish garden: a pure snow‑white hybrid tea rose that shines best in a sunny, well‑drained spot, even when Your soil tends towards heavy clay. Its buds are tall and refined, opening into very full, classic blooms that look at home in both cottage-style and modern front gardens. The uniform, bushy habit makes it easy to fit into smaller borders and ornamental beds, while the dense, glossy foliage gives the plant a finished, decorative look even between flushes. CASTA DIVA® is grown for You as a 6–12 month, own‑root plant in a 2‑litre pot, so it arrives already well rooted and ready to settle in. In year one it concentrates on establishing roots, in year two it builds up strong shoots, and from year three onwards it shows its full ornamental value with reliable, repeated flowering. The large, solitary blooms are ideal for cutting, giving You exhibition‑style stems for the vase straight from Your garden.

Information about the videos
The video series is not a “seasonal showcase”, but makes the essence of pharmaROSA® own-root production tangible: how the plant is built, what the root system is like and how the shoots renew themselves. The footage was therefore taken at different times, showing plants at different stages of development, so mixed leaf coverage or differing growth stages may appear in the videos. This is not a “sample” of the batch delivered, but an illustration of how the technology works. The current condition of the rose available to order — typical of the given period and similar to what you can expect to receive in the parcel — is shown at the top of the product page.
