Beautiful yet Noxious .. Tamarisk

A follow-up to Monday's post showing a gorgeous Tamarisk holding center stage at London's

Chelsea Physic Garden. As gardening/blogging compatriot, Helen, aka Toronto Gardens recently pointed out, Tamarix ramosissima is considered to be an invasive plant.

I have vivid memories of seeing a beauty such as the one pictured here in a private garden in Provence a few years ago. Yet, as responsible stewards of our own bits of the earth, we must respect the fact that while we might be swayed to plant this tree, it would be a mistake to do so.

Perhaps you'd like to visit another London garden with nary a Tamarisk in sight!

For your pleasure ... a 1.5 acre rooftop landscape cultivated in the very heart of London's Kensington District!

LONDON Calling .. Gardens Galore in the Weeks Ahead

So much to share: Here, a few sights/sites to revisit.

I've returned from the U.K. with stories to tell and garden gossip. After experiencing two weeks of cold weather, the sun appeared, blazing among the aisles of London's Chelsea Physic Garden; preening with Paeonia and poppies.

A scene-stealer... the brilliant Tamarisk.

Physician, entrepreneur, plant collector: Sir Hans Sloane stands watch over the Physic Garden's amazing flora. Imagine! I returned today just as the Chelsea Flower Show was about to kick off. And though I've attended this fabulous show in previous years, I had other plans to occupy my days on this sojourn.

Along Portobello Road, cascading golden panicles of Laburnum trees draped the sidewalks.

Look for garden touring from London to Wales, continuing in the weeks ahead here on

Jet lag notwithstanding.

Solitary Survivor .. Dendrobium Orchid

Hundreds of species and cultivars grow in Alice's garden ... but there is only one orchid:

Dendrobium x delicatum 'Extra Fine'

is blooming rather late this year. A single stem sends out flowers, unlike previous seasons, when sprays emerged from multiple stems. A dear friend passed this plant along, a savvy plantsman and native San Franciscan with impressive expertise in the sphere of orchid cultivation. I've managed to keep the plant alive, although a more tender specimen - Masdevallia coccinea 'Leywoods' did not survive. I'm appalled to report that I failed to provide winter protection for the tender Masdevallia orchid and it perished.

The Dendrobium receives a bit of coddling during the rainy season, when it's placed outside the french doors on the back porch. There, it avoids the worst of my micro-climate's winter frosts that drape the floor of the garden, and the onslaught of drenching rainfall, resulting in soggy conditions. Only .. one .. orchid.
