What to look for in May

Outdoor Gardens

Six different species of Cistus are flowering in Plants for a Changing Climate this month. Cistus are evergreen shrubs, native to the whole Mediterranean region, the Canary Islands and Madeira, and are an important constituent of the flora of maquis and garrigue – stony, arid, and degraded scrublands, roadsides, and woodland. They have showy flowers in white and several shades of pink, rather like single roses – hence the common name ‘rock rose’.

Each day’s flowers are borne in great abundance but last for only a few hours, scattering their silky petals on the ground. The leaves are adapted to reduce water loss in the Mediterranean sun, and some exude a fragrant, sticky gum called ladanum which is used in perfumery. Despite being native to the Mediterranean, most are reasonably hardy and thrive in our gardens when given the correct cultivation.

You can find them here at Eden flowering amidst colourful Anemone coronaria, brilliant yellow Euryops pectinatus, Fuchsia, Osteospermum, Scilla peruviana and Cytissus

Rainforest Biome

Malaysian outdoor living stimulates all the senses and our very own Malaysian home garden is no exception as it bursts with a myriad of newly planted crops. Hot, spicy chillies, aromatic coriander, aubergines and okra can be found as you wander through this intimate and luxuriant space. 

Close by, the Mysore clock vine (Thunbergia mysorensis), is once again weaving its magic over the archway with beautiful pink, trumpet-shaped flowers. The rosy periwinkle, (Catharanthus roseus), is also flowering amidst the verdant foliage of the Rainforest. This pretty plant bears masses of pink flowers with darker red centres, and is endemic to Madagascar where it’s endangered in the wild. 

Mediterranean Biome

The new, Mediterranean-style Italian kitchen garden highlights the value and diversity of heritage crops and foods – their historic and current uses and their roles in local cuisine, local industry, myth and medicine. There are flowers, herbs, fruits and vegetables all jostling for space – no planting in straight lines here. It’s a garden full of less well known varieties of vegetables, and those that have fallen from favour that have stories to tell. 

Meanwhile in Australia, Melaleuca and Callistemon are in bloom and the striking black and green kangaroo paw (Macropidia fuliginosa), continues to flower.

In South Africa, look out for the beautiful Watsonia and the purple-flowered Table Mountain Pelargonium, beyond the Pepsi pool. The bird of paradise (Strelitzia reginae), also puts in an appearance this month.

Highlights over the coming year…

What to look out for in spring
