{"product_id":"r-fastigiatum","title":"R. fastigiatum","description":"\u003cp\u003eR. fastigiatum with it small stature and tiny leaves is often sold as R. impeditum. We were introduced to the real impeditum a few years ago, but lost it. Now we grow R. fastigitum in its place. Both are small growers with blue\/purple flowers.  This species is super hardy, to -15 deg. F. Sharp drainage is very important for this small species to thrive. Adding gravel to the planting mix is a good idea. Flowering occurs in April to May. This plant will only be 12-18 inches high in 10 years \u003c\/p\u003e","brand":"Log Cabin Nursery","offers":[{"title":"1 gal size","offer_id":47160735858941,"sku":null,"price":35.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1342\/7035\/files\/fastigiatum.jpg?v=1769466868","url":"https:\/\/singtree.com\/products\/r-fastigiatum","provider":"Singing Tree Gardens Nursery","version":"1.0","type":"link"}
