The first bridge we planted was the Rose Garden Bridge, and our goal was to design something to give some life to a gray stone structure. Though color and blooms were the most important consideration, I asked if we could find plants that might have some degree of heat and drought tolerance, and there had to be several trailing elements as well. And another thing, not often considred when designing planters, they had to look good when viewed from below as tour boats go under this bridge. Here is what ended up in the planters:
Caberet Deep Blue Mini-Petunias (Calibrachoa x Cabaret™ Deep Blue)
Superbells® Double Lavender Mini Petunias (Calibrachoa x Superbells® Double Lavender)
Red Sensation False Dracena (Cordyline australis 'Red Sensation')
Bride's Cascade Mandevilla (Mandevilla 'Bride's Cascade')
Graffiti Lavender Pentas (Pentas lanceolata 'Graffiti Lavender')
Variegated Mexican Mint (Plectranthus amboinicus 'Variegatus')
Angelina Stonecrop (Sedum rupestre 'Angelina')
Gay’s Delight Coleus (Solenostemon scutellarioides ‘Gay’s Delight)
Purple Heart (Tradescantia pallida)
Aeonium arboreum atropurpureum 'Zwartkop'
Faucaria tigrina variegate
Portulaca grandiflora ‘Happy Hour Mix’
Portulaca oleracea ‘Rio Scarlet’
Sedum rupestre 'Angelina'
