Description
  • RHS Award of Garden Merit
  • The palm tree geranium
Geranium maderense is a magnificent tender perennial. The Madeira Cranesbill is the largest of the Geranium species, and certainly one of the most impressive, reaching a height of 1.5m (4',9"). Although perennial, it often acts as a biennial, producing pretty magenta pink blooms in its second year. But you won't mind the wait - it will give you time to appreciate the exotic-looking, dissected, evergreen foliage that radiates from a stout central trunk. This spectacular RHS AGM species will need some winter protection so it is best grown in the conservatory or a large patio container which can be moved to a frost free position in winter. Height: 150cm (59"). Spread: 100cm (39").

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Pot up geranium plants and grow them on in warm frost-free conditions. When all risk of frost has passed, gradually acclimatise geraniums to outdoor conditions over a period of 7 to 10 days before transplanting them into their final positions in containers or sheltered borders. Plant geraniums in a sunny or semi-shaded position, in any moist, well drained soil.
More Info
Feed and water geranium plants regularly, particularly during hot, dry periods. In autumn, before the first frosts, move containers of Geranium madarense to a bright, frost free position for the winter. Border grown plants must be lifted and repotted if they are to be kept for the following year. During the winter months, take care not to over water, keeping the compost moist but not wet.
