The Alpine Water fern is a tremendous little fern for giving evergreen ground cover at a low level, particularly useful for front of the border or rock garden pockets. The creeping rhizome spreads the plant into a small colony resembling a patch of upright, wiggly green maggots! However Blechnum penna-marina is never troublesomely invasive as, rooting close to the surface, it is easily removed from where unwanted. New growth is particularly colourful: bronze in shade but almost bright red in a sunny position. All in all a delightful and trouble free garden plant

Delivery location

Due to the nature of the consignments, the courier's drivers are not insured to carry goods through your property. The standard delivery location is the border of your property or the entrance of a communal space. If other arrangements need to be made, please get in touch with us as soon as the order is placed.
Vouchers and small boxes can be posted through the letterbox, provided there is unrestricted access to it. 

Pot sizes

With items such as ferns, juvenile tree ferns and herbaceous plants it is difficult to give the exact size of each species when such a wide range of plants are grown so we specify standard pot sizes to give an indication of the size and/or age of the plant you are buying.

Sometimes the pot size might vary slightly from the standard or we might listed as 2-3 litre pot, depending on the growers we purchased them from. However, the sizes of the plants are similar in height and spread.

Sometimes the plants might be photographed in decorative pots. However, please bear in mind that our plants are kept in plastic nursery pots.

Plant height

For the outdoor plants, that are meant to be planted in the ground, the height of the pot is excluded from the measurement. The height is measured from the top of the pot to the tallest leaf or branch of the plant.

All plants are measured when brought to our nursery, however, due to natural factors, the actual size of the plant might change over time due to adjustments to the environment. When picking multiple plants for an order, we aim to pick matching plants.

Excellent plants. Really strong, healthy ferns with a good root system present. Within the market place they represent great value. Palm Centre's service is excellent.
