In summer the salt marshes of Poole Harbour begin to show some colour other than the dark green that usually abounds. The lovely lavender blue of the common sea-lavender (Limonium vulgare) comes out and forms large tracts of blue on the marshes. This becomes especially evident from the double-decker hide at Arne.
Not a lavender at all, the sea-lavender is related to the pink thrift we see on the cliffs in early summer. The sea-lavender flowers in July and August, especially along the south and east coast where mudflats abound.
