Weight: 0.01 lbs

Cupplant - Silphium perfoliatum The large pointed leaves of the Cup Plant join its square shaped stems forming cups that catch and store rainwater so birds and butterflies often come for a drink and hummingbirds regularly visit. In the fall, goldfinches descend upon the plants to devour the seeds. The Cup Plant occurs naturally in moist environments but does very well when planted in the garden. SEED GERMINATION INFO Cold, moist stratification. Mix seed with moist but not wet, sterile growing medium. Place mixture in a labeled, sealed plastic bag and store in refridgerator for six to eight weeks. Note: Some seed may germinate in the storage bag if moist stratified too long. If sprouting occurs, plant immediately. Another method is to sow seed outdoors in late autumn so that they may overwinter. Approx. 1,400 seeds per oz. - 25 seeds per pack Colour : Yellow Blooms : July to Sept. Light : Full sun to Part shade Height : 3' - 10' Soil : Sand to Clay Water : Medium to Moist
