G. maderense is a robust but short-lived evergreen perennial, with attractively dissected leaves to 20cm in length and large panicles of purplish-pink flowers 4cm across, with darker centres
it grows up to 50cm tall and wide and have masses of pink flowers in summer (ours were adored by carder bees)
like a warm sheltered spot against a wall or in a cool glasshouse
Plants are first year seedlings in 7cm pot small but grow on to flower within 12 months, they are fast growing starting only small but being fully grown and in flower in a matter of months. These don't look much when small but they grow so quickly you will be surprised how they go from such little plants to full flower large plants in a single season. It's also normal for these to be shallow rooted.
Upon arrival unpack and water place in a cool semi shady spot to allow to recover from shipping. After a day or two these can be planted out. Dig a hole the size of the pot and fill with water. Sprinkle a handful of slow release food granules into the hole (this is optional but will give the plants an added boost and can be purchased with your order) soak the plant pot and remove the whole plant and its soil in one place directly into the hole back firm and firm in well to ensure their are no air pockets. Water in. Should the weather be hot during planting further watering may be necessary. Otherwise simply enjoy and trim back old flowers head once they have gone over.
