{"product_id":"sempervivum-ciliosum-var-borisii","title":"Sempervivum ciliosum var. borisii - Rare","description":"\u003cp\u003eSempervivum ciliosum var. borisii is a rare and highly sought-after variety from the mountain regions of Bulgaria, named in honour of Tsar Boris III of Bulgaria. It is distinguished by its dense covering of silvery-white hairs or cilia along the leaf margins, giving the compact rosettes a soft, frosted appearance that catches the light beautifully. This silvery coating is thought to reflect intense mountain sunlight and provide insulation against extreme cold, making it one of the most cold-hardy Sempervivums in existence. A true gem for collectors and alpine garden enthusiasts.\u003c\/p\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin-top: 12px;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight: bold; padding: 4px 10px 4px 0; vertical-align: top; white-space: nowrap;\"\u003e📐 Current Size\u003c\/td\u003e\n\u003ctd style=\"padding: 4px 0;\"\u003e3-5 cm across (May 2026) \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight: bold; padding: 4px 10px 4px 0; vertical-align: top; white-space: nowrap;\"\u003e☀️ Sun\u003c\/td\u003e\n\u003ctd style=\"padding: 4px 0;\"\u003eFull sun.
